It replaces OEM part numbers B25030001 and BTY00017. The DB Cox3 is a mobile POS device used by merchants in field and counter environments where battery condition directly affects transaction continuity.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eDB Cox3 platform fit:\u003c\/strong\u003e\n    The DB Cox3 uses a fixed 3.7V Li-Polymer cell with a specific connector and BMS handshake tied to the terminal's power management controller. This replacement matches that voltage rail and connector, so the terminal's charge IC recognises the cell correctly on first boot.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through full charge and discharge cycles on the DB Cox3 platform. The BMS accepted the handshake without fault codes, and the charge IC moved from bulk to top-off mode at the correct threshold.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst deployment cycle:\u003c\/strong\u003e\n    After installing this battery, complete at least one full transaction cycle — including a receipt print — before deploying in a live environment. The terminal maps cell capacity during normal operation and needs one complete power cycle to calibrate the charge indicator correctly.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eTerminal not completing PCI boot sequence after battery swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe DB Cox3 runs a PCI security boot check on startup that draws a short burst of current. If the new cell hasn't completed a full charge cycle, the BMS may flag the draw as an anomaly and hold the boot process. This is a BMS initialisation issue, not a fault with the battery or terminal. Charge the battery to 100% with the terminal off, then power on and allow the full boot sequence to complete before use.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eTerminal rebooting mid-transaction during receipt printing\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe receipt printer in the DB Cox3 creates a brief high-current spike that older or degraded cells can't sustain without triggering BMS overcurrent protection — causing an unexpected reboot. A new cell at full charge handles this spike without tripping the cutoff. If reboots persist after fitting a fresh battery, check that the cell is fully charged before the first transaction; voltage below 3.6V under printer load is enough to trip the protection circuit.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43415933714522,"sku":"BWCS-INC300SL-1","price":31.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43415933747290,"sku":"BWCS-INC300SL-2","price":36.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43415933780058,"sku":"BWCS-INC300SL-3","price":39.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-INC300SL-1.webp?v=1779758086","url":"https:\/\/batteryweb.com\/products\/ingenico-db-cox3-replacement-battery-37v-1800mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
