Capacity is 1800mAh (21.6Wh), matching the original cell specification. The pack uses the same Ni-MH chemistry as the factory unit to maintain BMS compatibility across all listed models.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003e686-6015 series compatibility:\u003c\/strong\u003e\n    These models share a common 12V power rail, connector format, and BMS handshake protocol. The charge controller on each device expects Ni-MH cell behaviour — specifically the delta-V termination signal — so substituting a different chemistry causes incorrect charge cutoff and false fault codes.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through charge and discharge on a 12V Ni-MH-compatible charge platform. The BMS accepted the cell, delta-V termination fired at the correct point, and no fault flags were raised across three consecutive cycles.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePower-on self-test after installation:\u003c\/strong\u003e\n    After fitting this battery, let the device complete its full startup self-test without interruption. Medical devices in this class run a BMS verification routine at boot. Interrupting it — even briefly cutting power — triggers a false battery fault that persists until the next clean reboot.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCharge indicator not reaching 100% on first charge with this battery\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe charge IC in these JCPenney medical devices applies a conservative current limit when it detects a new or unfamiliar cell. On first charge, the controller may stop short of a full 100% indication and report a partial fill. This is the delta-V detection algorithm being cautious, not a faulty pack. Run one complete charge-discharge cycle and the charge controller recalibrates its endpoint. After that first cycle, the indicator should reach full charge consistently.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eDevice shuts off mid-use in the first week after battery swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNew Ni-MH cells deliver their full rated capacity only after the first 5–10 charge-discharge cycles. Before that break-in period, the BMS may read the cell voltage as dropping below the low-voltage cutoff threshold under load — even though the pack is not actually depleted. The device interprets this voltage sag as a critical battery condition and shuts down as a safety measure. Complete several full charge-discharge cycles under normal use, and the sag should reduce to a level the BMS no longer flags. If shutdown continues past cycle 10, check that the terminal voltage under load stays above 10.8V.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381467381850,"sku":"BWCS-CBP308MD-1","price":105.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381467414618,"sku":"BWCS-CBP308MD-2","price":121.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381467447386,"sku":"BWCS-CBP308MD-3","price":133.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-CBP308MD_1.webp?v=1778901051","url":"https:\/\/batteryweb.com\/products\/jcpenney-686-6015-replacement-battery-12v-1800mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
