It fits the CV31 directly and matches OEM part numbers 1021AB01, VE33-8020-A0, and 213-042-001. Capacity is 12.4Wh — identical to the original specification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eThor CV31 vehicle terminal fit:\u003c\/strong\u003e\n    The CV31 uses a dedicated internal battery with a specific BMS handshake tied to its power management controller. This cell matches the voltage rail and connector profile the terminal expects, so the BMS initialises correctly on first insertion.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this battery through charge and discharge cycles on the CV31 platform. The BMS accepted the cell without error flags, voltage held stable under the terminal's boot sequence draw, and the protection circuit responded correctly to both charge cutoff and low-voltage events.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eHot-swap charge requirement on the CV31:\u003c\/strong\u003e\n    The CV31 draws peak current during boot — up to 10 seconds of sustained load. If you are using this cell as a hot-swap bridge during ignition cycles, charge it fully before installation. A partially charged cell may drop below the terminal's minimum boot voltage mid-sequence and fail to bridge the gap.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the Thor CV31 loses data during vehicle ignition start\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eWhen the vehicle cranks, the main supply voltage dips — sometimes to near zero for 2–4 seconds. The CV31 relies on its internal battery to bridge that gap and keep the terminal alive. If the internal battery is degraded or below roughly 3.4V, it cannot supply enough current to sustain the terminal through the ignition transient. The result is a cold boot, which wipes volatile memory and any unsaved session data. Replacing a degraded cell with a fully charged 3350mAh unit eliminates the drop-out.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eThor CV31 not booting when disconnected from vehicle power\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe CV31 requires a minimum battery voltage — typically above 3.2V — to initiate its boot sequence. A deeply discharged or end-of-life cell may sit below this threshold and show no response when the terminal is powered on without the vehicle supply connected. Reconnect the terminal to vehicle power for at least 30 minutes to bring the cell above the boot voltage floor, then attempt startup. If the cell still won't hold above 3.2V under load, replacement is the correct fix — not further charging.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43428090118234,"sku":"BWCS-ICV311BX-1","price":32.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43428090151002,"sku":"BWCS-ICV311BX-2","price":37.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43428090183770,"sku":"BWCS-ICV311BX-3","price":41.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-ICV311BX-1.webp?v=1779934037","url":"https:\/\/batteryweb.com\/products\/intermec-thor-cv31-replacement-battery-37v-3350mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
