| Business Description and Accounting Policies [Text Block] | 1. BASIS OF PRESENTATION The accompanying unaudited Consolidated Financial Statements of Ultralife Corporation (the “Company”) and its subsidiaries have been prepared in accordance with generally accepted accounting principles in the United States of America (“GAAP”) for interim financial information and with the instructions to Rule 8 -03 of Regulation S-X. Accordingly, they do not include all of the information and footnotes for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring accruals and adjustments) considered necessary for a fair presentation of the Consolidated Financial Statements have been included. Results for interim periods should not be considered indicative of results to be expected for a full year. Reference should be made to the Consolidated Financial Statements and related notes thereto contained in our Form 10 -K for the year ended December 31, 2018. The December 31, 2018 consolidated balance sheet data referenced herein was derived from audited financial statements, but does not include all disclosures required by GAAP.Certain items previously reported in specific financial statement captions have been reclassified to conform to the current presentation. 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.Recently Adopted Accounting Guidance Leases Effective January 1, 2019, the Company adopted Accounting Standards Update 2016 -02 – Leases (Topic 842 ). Adoption of the new standard did not materially impact the prior year consolidated statements of operations and cash flows. The prior year consolidated balance sheet has been revised for the effects of the new standard. The effects to our consolidated balance sheet as of December 31, 2018 are presented below.The Company adopted the new standard applying the modified retrospective approach. The Company measured and recognized leases upon adoption which had commenced as of the beginning or during the prior year. The package of practical expedients permitted under the transition guidance of the new standard was elected which allowed us to carry forward the historical lease classification and determination of whether an arrangement is or contains a lease on existing leases. The use-of-hindsight transition practical expedient was applied to determine the lease term for existing leases, which resulted in the lengthening of the lease term at commencement for one of our operating facilities.At contract inception, the Company determines whether the arrangement is or contains a lease and determines the lease classification. The lease term is determined based on the noncancellable term of the lease adjusted to the extent optional renewal terms and termination rights are reasonably certain. Lease expense is recognized evenly over the lease term. Variable lease payments are recognized as period costs. The present value of remaining lease payments are recognized as a liability on the balance sheet with a corresponding right-of-use asset adjusted for prepaid or accrued lease payments. The Company uses its incremental borrowing rate for the discount rate, unless the interest rate implicit in the lease contract is readily determinable. The Company has adopted the practical expedients to not separate non-lease components from lease components and to not present short-term leases on the balance sheet.The impact on the consolidated balance sheet as of December 31, 2018 is shown below.Impact to Previously Reported Results Consolidated Balance Sheet as of December 31, 2018:
See Note 9 for further disclosure regarding lease accounting.Recent Accounting Guidance Not Yet AdoptedThere 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 2018 Annual Report on Form 10 -K. |

| Subsequent Events [Text Block] | 2. SUBSEQUENT EVENTSAcquisition of Southwest Electronic Energy Corporation On May 1, 2019, Ultralife Corporation completed the acquisition of 100% of the issued and outstanding shares of Southwest Electronic Energy Corporation (“SWE”) for an aggregate purchase price of $25.0 million in cash, net of cash acquired and subject to customary post-closing working capital adjustments.SWE is a leading independent designer and manufacturer of high-performance smart battery systems and battery packs to customer specifications using lithium cells. SWE serves a variety of industrial markets, including oil & gas, remote monitoring, process control and marine, which demand uncompromised safety, service, reliability and quality. The Company acquired SWE as a bolt-on acquisition to further support our strategy of commercial revenue diversification by providing entry to the oil and gas exploration and production, and subsea electrification markets, which are currently unserved by Ultralife. Another key benefit includes obtaining a highly valuable technical team of battery pack and charger system engineers and technicians to add to our new product development-based revenue growth initiatives in our commercial end-markets particularly asset tracking, smart metering and other industrial applications. The SWE acquisition was completed pursuant to a Stock Purchase Agreement dated May 1, 2019 ( the “Stock Purchase Agreement”) by and among Ultralife, SWE, Southwest Electronic Energy Medical Research Institute, a Texas non-profit (the “Seller”), and Claude Leonard Benckenstein, an individual (the “Shareholder”).The aggregate purchase price for the SWE Acquisition was funded by the Company through a combination of cash on hand and borrowings under the Credit Facilities (see Note 3 ).The Stock Purchase Agreement contains customary terms and conditions including representations, warranties and indemnification provisions. A portion of the consideration paid to the Seller will be held in escrow for post-closing adjustments and indemnification purposes. The acquisition of SWE will be accounted for as a business combination, and accordingly, the assets acquired and liabilities assumed will be recognized at fair value as of the acquisition date. The operating results and cash flows of SWE will be included in the consolidated financial statements from the date of acquisition in the Company's Battery & Energy Products segment. Due to the timing of the acquisition, the initial accounting is not yet complete. The Company is in the process of preparing the preliminary estimate of the fair value of assets acquired and liabilities assumed and the associated adjustments for supplemental pro forma revenue and earnings information.First Amendment Agreement On May 1, 2019, in connection with the SWE acquisition, the Company entered into the First Amendment Agreement with KeyBank National Association. See Note 3 for further information. |

| Debt Disclosure [Text Block] | 3. CREDIT FACILITY On May 1, 2019, Ultralife, SWE, and CLB, INC., a Texas corporation and wholly owned subsidiary of SWE (“CLB”), as borrowers, entered into the First Amendment Agreement (the “First Amendment Agreement”) with KeyBank National Association (“KeyBank” or the “Bank”), as lender and administrative agent, to amend the Credit and Security Agreement by and among Ultralife and KeyBank dated May 31, 2017 ( the “Credit Agreement”, and together with the First Amendment Agreement, the “Amended Credit Agreement”).The Amended Credit Agreement, among other things, provides for a five -year, $8.0 million senior secured term loan (the “Term Loan Facility”) and extends the term of the $30.0 million senior secured revolving credit facility (the “Revolving Credit Facility”, and together with the Term Loan Facility, the “Credit Facilities”) through May 31, 2022. Up to six months prior to May 31, 2022, the Revolving Credit Facility may be increased to $50.0 million with the Bank’s concurrence.Upon closing of the SWE Acquisition on May 1, 2019, the Company drew down the full amount of the Term Loan Facility and $6.8 million under the Revolving Credit Facility. The remaining availability under the Revolving Credit Facility is subject to certain borrowing base limits based on receivables and inventories.The Company is required to repay the borrowings under the Term Loan Facility in sixty (60 ) equal consecutive monthly payments commencing on May 31, 2019, in arrears, together with applicable interest. All unpaid principal and accrued and unpaid interest with respect to the Term Loan Facility is due and payable in full on April 30, 2024. All unpaid principal and accrued and unpaid interest with respect to the Revolving Credit Facility is due and payable in full on May 31, 2022. The Company may voluntarily prepay principal amounts outstanding at any time subject to certain restrictions.In addition to the customary affirmative and negative covenants, the Company must maintain a consolidated fixed charge coverage ratio of equal to or greater than 1.15 to 1.0, and a consolidated senior leverage ratio of equal to or less than 2.5 to 1.0, each as defined in the Amended Credit Agreement.Borrowings under the Credit Facilities are secured by substantially all the assets of the Company. Interest will accrue on outstanding indebtedness under the Credit Facilities at the Base Rate or the Overnight LIBOR Rate, as selected by the Company, plus the applicable margin. The Base Rate is the higher of (a) the Prime Rate, (b) the Federal Funds Effective Rate plus 50 basis points, and (c) the Overnight LIBOR Rate plus one hundred basis points. The applicable margin ranges from zero to negative 50 basis points for the Base Rate and from 185 to 215 basis points for the Overnight LIBOR Rate and are determined based on the Company’s senior leverage ratio.The Company must pay a fee of 0.1% to 0.2% based on the average daily unused availability under the Revolving Credit Facility.Payments must be made by the Company to the extent borrowings exceed the maximum amount then permitted to be drawn on the Credit Facilities and from the proceeds of certain transactions. Upon the occurrence of an event of default, the outstanding obligations may be accelerated and the Bank will have other customary remedies including resort to the security interest the Company provided to the Bank. |

| Earnings Per Share [Text Block] | 5. EARNINGS PER SHARE Basic earnings per share (“EPS”) is computed by dividing earnings attributable to the Company’s common shareholders 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 March 31, 2019, 1,052,410 stock options and 11,666 restricted stock awards were included in the calculation of Diluted EPS as such securities are dilutive. Inclusion of these securities resulted in 484,843 additional shares in the calculation of fully diluted earnings per share. For the comparable three -month period ended April 1, 2018, 1,324,753 stock options and 17,500 restricted stock awards were included in the calculation of Diluted EPS resulting in 498,109 additional shares in the calculation of fully diluted earnings per share. There were 448,250 and 214,000 outstanding stock options for the three -month periods ended March 31, 2019 and April 1, 2018, respectively, which were not included in EPS as the effect would be anti-dilutive. |

| Income Tax Disclosure [Text Block] | 8. INCOME TAXES Our effective tax rate for the three months ended March 31, 2019 and April 1, 2018 was 8% and 3%, respectively. The increase in our effective tax rate for the current quarter compared to the prior quarter was primarily due to the reversal of the valuation allowance on our U.S. deferred tax assets as of December 31, 2018. Our effective tax rate for the three months ended March 31, 2019 was lower than the U.S. federal statutory rate primarily due to tax benefits relating to the exercise of stock options during the period.As of March 31, 2019, we have domestic net operating losses (“NOL”) carryforwards of $63,388, which expire 2019 thru 2035, and domestic tax credits of $1,817, which expire 2028 thru 2037, available to reduce future taxable income. Management has concluded it is more likely than not that these domestic NOL and credit carryforwards will be fully utilized.As of March 31, 2019, for certain past operations in the U.K., we continue to report a valuation allowance for NOL carryforwards of approximately $10,000, nearly all of which can be carried forward indefinitely. Utilization of the net operating losses may be limited due to the change in the past U.K. operation and cannot currently be used to reduce taxable income at our other U.K. subsidiary, Accutronics Ltd.As of March 31, 2019, we have not recognized a valuation allowance against our other foreign deferred tax assets, as realization is considered to be more likely than not. As of March 31, 2019, the Company maintains its assertion that all foreign earnings will be indefinitely reinvested in those operations.There were no March 31, 2019 and December 31, 2018. 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 2000 through 2018 remain subject to examination by the Internal Revenue Service (“IRS”) due to our net operating loss carryforwards. Our U.S. tax matters for the years 2000 through 2018 remain subject to examination by various state and local tax jurisdictions due to our net operating loss carryforwards. Our tax matters for the years 2010 through 2018 remain subject to examination by the respective foreign tax jurisdiction authorities. |

| New Accounting Pronouncements, Policy [Policy Text Block] | Recently Adopted Accounting Guidance Leases Effective January 1, 2019, the Company adopted Accounting Standards Update 2016 -02 – Leases (Topic 842 ). Adoption of the new standard did not materially impact the prior year consolidated statements of operations and cash flows. The prior year consolidated balance sheet has been revised for the effects of the new standard. The effects to our consolidated balance sheet as of December 31, 2018 are presented below.The Company adopted the new standard applying the modified retrospective approach. The Company measured and recognized leases upon adoption which had commenced as of the beginning or during the prior year. The package of practical expedients permitted under the transition guidance of the new standard was elected which allowed us to carry forward the historical lease classification and determination of whether an arrangement is or contains a lease on existing leases. The use-of-hindsight transition practical expedient was applied to determine the lease term for existing leases, which resulted in the lengthening of the lease term at commencement for one of our operating facilities.At contract inception, the Company determines whether the arrangement is or contains a lease and determines the lease classification. The lease term is determined based on the noncancellable term of the lease adjusted to the extent optional renewal terms and termination rights are reasonably certain. Lease expense is recognized evenly over the lease term. Variable lease payments are recognized as period costs. The present value of remaining lease payments are recognized as a liability on the balance sheet with a corresponding right-of-use asset adjusted for prepaid or accrued lease payments. The Company uses its incremental borrowing rate for the discount rate, unless the interest rate implicit in the lease contract is readily determinable. The Company has adopted the practical expedients to not separate non-lease components from lease components and to not present short-term leases on the balance sheet.The impact on the consolidated balance sheet as of December 31, 2018 is shown below.Impact to Previously Reported Results Consolidated Balance Sheet as of December 31, 2018:
See Note 9 for further disclosure regarding lease accounting.Recent Accounting Guidance Not Yet AdoptedThere 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 2018 Annual Report on Form 10 -K. |
