The December 31, 2017 consolidated balance sheet data referenced herein was derived from audited financial statements, but does not include all disclosures required by GAAP.Our monthly closing schedule is a 4/4/5 weekly-based cycle for each fiscal quarter, as opposed to a calendar month-based cycle for each fiscal quarter. While the actual dates for the quarter-ends will change slightly each year, we believe that there are not any material differences when making quarterly comparisons. |

| Revenue from Contract with Customer [Text Block] |
Effective January 1, 2018, the Company adopted Accounting Standards Update 2014 -09 (Topic 606 ) “Revenue from Contracts with Customers”. Adoption of Topic 606 did not impact the timing of revenue recognition in our Consolidated Financial Statements for the current or prior interim or annual periods. Accordingly, no adjustments have been made to opening retained earnings or prior period amounts.Revenue Recognition Revenues are generated from the sale of products. Performance obligations are met and revenue is recognized upon transfer of control to the customer, which is generally upon shipment. When contract terms require transfer of control upon delivery at a customer’s location, revenue is recognized on the date of delivery. Revenue is measured as the amount of consideration we expect to receive in exchange for shipped product. Sales, value-added and other taxes billed and collected from customers are excluded from revenue. Customers, including distributors, do not have a general right of return. For products shipped under vendor managed inventory arrangements, revenue is recognized and billed when the product is consumed by the customer, at which point control has transferred and there are no further obligations by the Company.Revenues recognized from prior period performance obligations for the three and nine months ended September 30, 2018 were not material.As of September 30, 2018, the Company had no unsatisfied performance obligations for contracts with an original expected duration of greater than one year. Pursuant to Topic 606, we have applied the practical expedient with respect to disclosure of the deferral and future expected timing of revenue recognition for transaction price allocated to remaining performance obligations.Deferred revenue, unbilled revenue and deferred contract costs recorded on our Consolidated Balance Sheets as of September 30, 2018 and December 31, 2017 were not material.Accounts Receivable We extend credit to our customers in the normal course of business. We perform ongoing credit evaluations and generally do not require collateral. Payment terms are generally 30 days. Trade accounts receivable are recorded at their invoiced amounts, net of allowance for doubtful accounts. We evaluate the adequacy of our allowance for doubtful accounts quarterly. Accounts outstanding for longer than contractual payment terms are considered past due and are reviewed for collectability. We maintain reserves for potential credit losses based upon our historical experience and the aging of specific receivables. Receivable balances are written off when collection is deemed unlikely.Sales Commissions Sales commissions are expensed as incurred for contracts with an expected duration of one year or less. There were no sales commissions capitalized as of September 30, 2018. Shipping and Handling Costs Costs incurred by us related to shipping and handling are included in cost of products sold. Amounts charged to customers pertaining to these costs are reflected as revenue. Product Warranties We generally offer warranties against product defects. Costs incurred to service warranty claims are recorded as costs of products sold. We provide for potential warranty costs based on historical experience. Provision for warranty costs is recorded in other current liabilities and other long-term liabilities on our Consolidated Balance Sheets based on the duration of the warranty. The Company does not offer separate service-type warranties on its products.See Note 12 for disaggregated revenue information. |

| Debt Disclosure [Text Block] |
Credit Facilities On May 31, 2017, Ultralife Corporation entered into a Credit and Security Agreement (the “Credit Agreement”) and related security agreements with KeyBank National Association (“KeyBank” or the “Bank”) to establish a $30,000 senior secured, cash flow-based, revolving credit facility that includes a $1,500 letter of credit subfacility (the “Credit Facility”). The Credit Agreement provides that the Credit Facility may be increased with the Bank’s concurrence to $50,000 prior to the last six months of the term and is scheduled to expire on May 30, 2020. The Credit Facility replaces the Company’s asset-based revolving credit facility with PNC Bank National Association which expired in accordance with its terms on May 24, 2017 ( the “Prior Credit Agreement”).The Credit Facility provides the Company with an aggregate of up to $30,000 of loan and letter of credit availability determined based on a borrowing base formula. The Company may use advances under the Credit Facility for general working capital purposes, to reimburse drawings under letters of credit and to fund capital expenditures and acquisitions, all subject to the terms of the Credit Agreement. The Company had no amounts drawn under the Prior Credit Agreement at the time of its expiration and has not borrowed under the Credit Facility.Interest will accrue on outstanding indebtedness under the Credit Agreement at the Overnight LIBOR Rate plus the applicable margin, or at the Base Rate plus the applicable margin, as selected by the Company. During the period beginning May 31, 2017 and ending April 1, 2018, the applicable margin for Overnight LIBOR Loans is 185 basis points, the applicable margin for Base Rate Loans is negative 50 basis points and applicable margin for the Unused Fee is 20 basis points. Beginning April 2, 2018 and thereafter, the applicable margins will be determined based on the chart below.
The Company must pay a fee on its unused availability equal to the applicable margin for the Unused Fee and customary letter of credit fees. In addition to the affirmative and negative covenants, the Company must maintain a fixed charge coverage ratio of 1.15 to 1.0, tested each fiscal quarter for the trailing four fiscal quarters, and a minimum tangible net worth of $40,000, tested as of the end of each calendar year. The Company was in full compliance with its covenants as of September 30, 2018. Any outstanding borrowings must be repaid upon expiration of the term of the Credit Facility. Payments must be made during the term to the extent outstanding borrowings exceed the maximum amount then permitted to be drawn as borrowings under the Credit Facility and from the proceeds of certain transactions. Upon the occurrence of an event of default, the outstanding obligations of the Company under the Credit Facility may be accelerated in addition to the other remedies available to the Bank under the terms of the Credit Agreement. The Credit Facility is secured by substantially all the assets of the Company.As of September 30, 2018, we had no outstanding balance under the Credit Facility and no outstanding letters of credit related to the Credit Facility. |

| Shareholders' Equity and Share-based Payments [Text Block] |
We recorded non-cash stock compensation expense in each period as follows:
We have stock options outstanding from various stock-based employee compensation plans for which we record compensation cost relating to share-based payment transactions in our financial statements. As of September 30, 2018, there was $681 of total unrecognized compensation cost related to outstanding stock options, which is expected to be recognized over a weighted average period of 1.1 years.The following table summarizes stock option activity for the nine -month period ended September 30, 2018:
The following assumptions were used to value stock options granted during the nine months ended September 30, 2018:
The weighted average grant date fair value of options granted during the nine months ended September 30, 2018 was $4.22. On July 25, 2018, the Company’s Board of Directors, at the recommendation of the Compensation and Management Committee and pursuant to the Company’s Amended and Restated 2004 Long-Term Incentive Plan, modified the option previously granted to the Company’s President and Chief Executive Officer to purchase an aggregate 200,000 shares of the Company’s common stock at $10.00, such that the option will fully vest immediately upon the Company’s common stock first reaching a closing price $10.00 for 15 trading days in a 30 trading-day period. The option as previously granted provided for vesting in annual increments of 50,000 shares on each of the four anniversaries of the date the Company’s common stock first reached a closing price $10.00 for 15 trading days in a 30 trading-day period. The option became fully vested during the third quarter 2018 and expires December 30, 2020. The transaction has been accounted for as an equity award modification pursuant to Accounting Standards Codification Topic 718, Compensation – Stock Compensation. The Company has recognized for the third quarter 2018 compensation cost of approximately $182, representing the incremental fair value of the modified award computed as of the modification date as the difference between the fair value of the modified award and the fair value of the original award immediately before it was modified. The incremental fair value was determined using a Monte Carlo simulation option-pricing model consistent with the valuation methodology used to value and recognize the original award.FASB’s guidance for share-based payments requires cash flows from excess tax benefits to be classified as a part of cash flows from financing activities. Excess tax benefits are realized tax benefits from tax deductions for exercised stock options in excess of the deferred tax asset attributable to stock compensation costs for such stock options. We did not record any excess tax benefits in the first nine months of 2018 or 2017. Cash received from stock option exercises under our stock-based compensation plans for the three -month periods ended September 30, 2018 and October 1, 2017 was $64 and $131, respectively. Cash received from stock option exercises under our stock-based compensation plans for the nine -month periods ended September 30, 2018 and October 1, 2017 was $1,357 and $1,120, respectively.In January 2018, 17,500 shares of restricted stock were awarded to certain of our employees. These shares vest in equal annual installments over three years. The weighted average grant date fair value of these awards was $7.16 per share. Unrecognized compensation cost related to these restricted shares was $71 at September 30, 2018. |

| Income Tax Disclosure [Text Block] |
On December 22, 2017, the U.S. government enacted comprehensive tax legislation commonly referred to as the Tax Cuts and Jobs Act (the “Tax Act”). The Tax Act makes broad and complex changes to the U.S. tax code, including, but not limited to, (1 ) reducing the U.S. federal corporate tax rate from 35 percent to 21 percent; (2 ) elimination of the corporate alternative minimum tax (AMT) and changing how existing AMT credits can be realized; (3 ) changing rules related to usage and limitation of net operating loss carryforwards created in tax years beginning after December 31, 2017; ( 4 ) generally eliminating U.S. federal income taxes on dividends from foreign subsidiaries for tax years beginning after December 31, 2017; and (5 ) implementing a territorial tax system and imposing a transition toll tax on deemed repatriated earnings of foreign subsidiaries. The Act provided for a one -time deemed mandatory repatriation for post-1986 undistributed foreign subsidiary earnings and profits (“E&P”) through the year ended December 31, 2017. The Company had a deficit in foreign E&P and is not expected to be subject to the deemed mandatory repatriation.On December 22, 2017, the SEC staff issued Staff Accounting Bulletin No. 118 to address the application of U.S. GAAP in situations when a registrant does not have the necessary information available, prepared, or analyzed (including computations) in reasonable detail to complete the accounting for certain income tax effects of the Tax Act. At September 30, 2018, the amounts recorded for the Tax Act remain provisional for the transition tax, the remeasurement of deferred taxes, and our reassessment of permanently reinvested earnings, uncertain tax positions and valuation allowances. These estimates may be impacted by further analysis and future clarification and guidance regarding available tax accounting methods and elections, earnings and profits computations, state tax conformity to federal tax changes and the impact of the Global Intangible Low-Taxed Income (“GILTI”) provisions. At September 30, 2018, we were not able to reasonably estimate, and therefore have not recorded, deferred taxes for the GILTI provisions. We have not yet determined our policy election with respect to whether to record deferred taxes for basis differences expected to reverse as a result of the GILTI provisions in future periods or use the period cost method.For the three -month periods ended September 30, 2018 and October 1, 2017, we recognized $86 and $104, respectively, in income tax expense. For the nine -month periods ended September 30, 2018 and October 1, 2017, we recognized $219 and $370, respectively, in income tax expense. These are detailed as follows:
The deferred income tax provision for the three -month and nine -month periods ended September 30, 2018 represents the increase in the taxable temporary difference related to goodwill and certain other indefinite-lived intangible assets of the U.S. operations that cannot be predicted to reverse for book purposes during our loss carryforward periods, partially offset by the amortization of certain intangible assets of Accutronics (U.K.). The deferred income tax provision for the three -month and nine -month periods ended October 1, 2017 reflects the higher previously-enacted U.S corporate tax rate. The current income tax provisions for 2018 and 2017 are primarily due to the income generated by our foreign operations during the respective periods.Our effective consolidated tax rates for the nine -month periods ended September 30, 2018 and October 1, 2017 were:
In 2018 and 2017, in the U.S. and for certain past operations in the U.K., we recognize a valuation allowance for our net operating loss carryforwards and other deferred tax assets that cannot be offset by reversing temporary differences. The recognition of the valuation allowance is based on an assessment of all available evidence, both positive and negative, weighted based on objective verifiability. The assessment of the realizability of the U.S. deferred tax assets was based on a number of factors including our history of operating losses, our historical operating volatility, our historical inability to accurately forecast earnings for future periods and the continued uncertainty of the general business climate. The use of our U.K. net operating loss carryforwards may be limited due to the change in the past U.K. operation. Based on our assessment of all available evidence and its weighting based on objective verifiability, we concluded that the realizability of these deferred tax assets is not more likely than not at September 30, 2018. In both 2018 and 2017, we have not recognized a valuation allowance against our other foreign deferred tax assets as we believe that it is more likely than not that they will be realized. We will continue to evaluate the realizability of our deferred tax assets in future periods.As of December 31, 2017, we have domestic and foreign net operating losses (“NOL”) totaling approximately $69,594 and $12,760, respectively, and domestic tax credits of approximately $1,837, available to reduce future taxable income. Included in our NOL carryforwards are foreign loss carryforwards of approximately $12,760, nearly all of which can be carried forward indefinitely. The domestic NOL carryforward of $69,594 expires beginning in 2020 through 2034. As of September 30, 2018, the Company maintains its assertion that all foreign earnings will be indefinitely reinvested in those operations.There were no unrecognized tax benefits related to uncertain tax positions at September 30, 2018 and December 31, 2017. As a result of our operations, we file income tax returns in various jurisdictions including U.S. federal, U.S. state and foreign jurisdictions. We are routinely subject to examination by taxing authorities in these various jurisdictions. Our U.S. tax matters for the years 2002 through 2017 remain subject to examination by the Internal Revenue Service (“IRS”) and various state and local tax jurisdictions due to our NOL carryforwards. Our tax matters for the years 2009 through 2017 remain subject to examination by the respective foreign tax jurisdiction authorities. |

| Earnings Per Share [Text Block] |
Basic earnings per share (“EPS”) is computed by dividing net income attributable to Ultralife Corporation by the weighted-average shares outstanding during the period. Diluted EPS includes the dilutive effect of securities, if any, and is calculated using the treasury stock method. For the three -month period ended September 30, 2018, 1,252,502 stock options and 17,500 restricted stock awards were included in the calculation of Diluted EPS as such securities are dilutive. Inclusion of these securities resulted in 571,829 additional shares in the calculation of fully diluted earnings per share. For the comparable three -month period ended October 1, 2017, 1,481,844 stock options and no restricted stock awards were included in the calculation of Diluted EPS resulting in 407,668 additional shares in the calculation of fully diluted earnings per share. For the nine -month periods ended September 30, 2018 and October 1, 2017, 1,252,502 and 1,066,844 stock options and 17,500 and zero restricted stock awards, respectively, were included in the calculation of Diluted EPS as such securities are dilutive. Inclusion of these securities resulted in 548,004 and 323,217 additional shares, respectively, in the calculation of fully diluted earnings per share.There were 5 02,250 and 569,000 outstanding stock options for the three -month periods ended September 30, 2018 and October 1, 2017, respectively, which were not included in EPS as the effect would be anti-dilutive. There were 5 02,250 and 984,000 outstanding stock options for the nine -month periods ended September 30, 2018 and October 1, 2017, respectively, which were not included in EPS as the effect would be anti-dilutive. |

a. Purchase Commitments As of September 30, 2018, we have made commitments to purchase approximately $3,230 of production machinery and equipment.b. Product Warranties We estimate future costs associated with expected product failure rates, material usage and service costs in the development of our warranty obligations. Warranty reserves are based on historical experience of warranty claims and generally will be estimated as a percentage of sales over the warranty period. In the event the actual results of these items differ from the estimates, an adjustment to the warranty obligation would be recorded. Changes in our product warranty liability during the first nine months of 2018 and 2017 were as follows:
c. Contingencies and Legal Matters We are subject to legal proceedings and claims that arise from time to time in the normal course of business. We believe that the final disposition of such matters will not have a material adverse effect on our financial position, results of operations or cash flows.Dreamliner Litigation In July 2013, an unoccupied Boeing 787 Dreamliner aircraft operated by Ethiopian Airlines was damaged by fire while parked at London Heathrow Airport. Following an investigation of this incident conducted by U.K. and U.S. regulatory authorities as well as by the manufacturer of the aircraft, a final report was issued by the Air Accidents Investigative Branch – UK Civil Aviation regulatory authority, with findings indicating that the fire was primarily caused by circumstances related to the plane’s emergency locator transmitter (“ELT”) manufactured and installed by another company. A component of the ELT is a battery pack which incorporates Ultralife’s industry-standard lithium manganese dioxide non-rechargeable D-cell, which Ultralife has produced since 2001, with wide-use in global defense and commercial applications.On May 4, 2015, we were notified of a lawsuit in which we were named, along with other suppliers to the aircraft manufacturer, concerning that 2013 fire, which was filed by Ethiopian Airlines Enterprise in the Commercial Court, Queen’s Bench Division of the High Court of Justice, London. We immediately referred this matter to our insurers.This lawsuit has now been resolved ( February 2018), the claimant has terminated the action against the Company, and the Court has acknowledged and consented to this termination. The matter was terminated without financial consequences to the Company. |

| New Accounting Pronouncements and Changes in Accounting Principles [Text Block] |
In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update 2014 -09 (Topic 606 ) “Revenue from Contracts with Customers” related to revenue from contracts with customers. Under this standard, revenue is recognized when promised goods or services are transferred to customers in an amount that reflects the consideration that is expected to be received for those goods or services. The updated standard will replace most existing revenue recognition guidance under GAAP and permits the use of either the retrospective or cumulative effect transition method. Topic 606 is effective for annual reporting periods beginning after December 15, 2017, including interim periods within that reporting period. The Company has adopted Topic 606 effective January 1, 2018. See Note 2 for further discussion.In November 2016, the FASB issued Accounting Standards Update 2016 -18, “Statement of Cash Flows (Topic 230 ): Restricted Cash”. The standard is effective for fiscal years beginning after December 31, 2017, and interim periods within those fiscal years, and should be applied using a retrospective transition method for each period presented. The standard requires that amounts generally described as restricted cash and restricted cash equivalents be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total cash amounts shown on the statements of cash flows. The Company has adopted this standard effective January 1, 2018. As a result, restricted cash has been included in the total cash amounts on the Company’s Consolidated Statement of Cash Flows for all periods presented and the required disclosures have been included in the Notes to Consolidated Financial Statements.In August 2016, the FASB issued Accounting Standards Update 2016 -15, “Statement of Cash Flows (Topic 230 ), Classification of Certain Cash Receipts and Cash Payments”. The standard makes eight targeted changes to how cash receipts and cash payments are presented and classified in the statement of cash flows. The standard is effective for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. The standard requires adoption on a retrospective basis unless it is impracticable to apply, in which case the Company would be required to apply the amendments prospectively as of the earliest date practicable. The Company has adopted this standard effective January 1, 2018. Adoption of this standard did not impact our Consolidated Financial Statements for the current or prior periods presented.In May 2017, the FASB issued Accounting Standards Update 2017 -09, “Compensation – Stock Compensation (Topic 718 ) – Scope of Modification Accounting”, which provides guidance about which changes to the terms or conditions of a share-based payment award require an entity to apply modification accounting in Topic 718. The standard is effective for fiscal years beginning after December 15, 2017 and interim periods within those fiscal years. The standard is to be applied on a prospective basis to an award modified on or after the adoption date. The Company has adopted this standard effective January 1, 2018. Adoption of this standard did not impact our Consolidated Financial Statements.There have been no developments to recently issued accounting standards, including the expected dates of adoption and anticipated effects on the Company’s Consolidated Financial Statements, from those disclosed in the Company’s 2017 Annual Report on Form 10 -K, except for the following:In March 2018, the FASB issued Accounting Standards Update 2018 -05, “Income Taxes (Topic 740 ): Amendments to SEC Paragraphs Pursuant to SEC Staff Accounting Bulletin No. 118”. The standard adds various Securities and Exchange Commission (“SEC”) paragraphs pursuant to the issuance of the December 2017 SEC Staff Accounting Bulletin No. 118, “Income Tax Accounting Implications of the Tax Cuts and Jobs Act” (“SAB 118” ), which was effective immediately. The SEC issued SAB 118 to address concerns about reporting entities’ ability to timely comply with the accounting requirements to recognize all of the effects of the Tax Cuts and Jobs Act in the period of enactment. SAB 118 allows disclosure that timely determination of some or all of the income tax effects from the Tax Cuts and Jobs Act are incomplete by the due date of the financial statements and if possible to provide a reasonable estimate. We have accounted for the tax effects of the Tax Cuts and Jobs Act under the guidance of SAB 118. We have determined reasonable estimates for those effects and have recorded provisional amounts in our Consolidated Financial Statements as of September 30, 2018 and December 31, 2017. |
