It replaces OEM part number ZQ-12 directly. Capacity is 2600mAh (37.44Wh), matching the original cell specification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eWPD-0080 series compatibility:\u003c\/strong\u003e\n    These models share the same 14.4V power rail, connector footprint, and BMS handshake protocol, which is why one cell covers the full platform. Swapping between compatible models in this lineup does not require firmware changes or recalibration.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through charge-discharge on the WPD-0080 platform and confirmed the BMS accepted the cell without throwing a fault code. Charge IC reached full termination voltage, and the self-test passed cleanly after the first full cycle.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-installation self-test protocol:\u003c\/strong\u003e\n    After fitting this battery, let the device complete its full power-on self-test without interruption. Medical devices in this class run a BMS verification routine at startup — cutting power mid-sequence flags a battery fault that sticks until the next clean reboot, not because the cell is faulty.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the WPD-0080 reports low battery immediately after a confirmed full charge\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe WPD-0080's BMS stores a capacity baseline calibrated to the original OEM cell chemistry. A new replacement cell hasn't yet completed a learn cycle, so the BMS measures state-of-charge against a reference it hasn't updated. The device reads the new cell as partially depleted even when the charge IC shows full termination. One complete charge-discharge cycle lets the BMS recalibrate and clears the false low-battery alarm. Until that cycle runs, the alarm is a calibration artefact, not a fault with the battery.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eDevice will not power on after replacement cell sat in storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion cells self-discharge during storage, and if the pack voltage drops below the BMS recovery threshold — typically around 10V for a 14.4V nominal cell — the BMS enters lockout to prevent damage. The device appears completely dead, but the cell is recoverable. Connect the battery to the device charger and leave it for at least 30 minutes before attempting to power on. Most BMS circuits begin a low-current pre-charge recovery below 10.8V and return to normal charge mode once the pack climbs back above that threshold.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381365178458,"sku":"BWCS-ZRW835MD-1","price":76.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381365211226,"sku":"BWCS-ZRW835MD-2","price":90.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381365243994,"sku":"BWCS-ZRW835MD-3","price":101.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-ZRW835MD_1.webp?v=1778900304","url":"https:\/\/batteryweb.com\/products\/zoncare-wpd-0080-replacement-battery-144v-2600mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
