It restores wireless operation to handsets that no longer hold a charge. Capacity is 850mAh (3.06Wh), matching the original specification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eGP85AAALH3BXZ platform fit:\u003c\/strong\u003e\n    These cordless handsets share a matched voltage rail and connector format tied to the 3.6V three-cell AAA Ni-MH configuration. The base station charger circuit expects this chemistry and voltage window — swapping to a different chemistry type will cause charging errors or cell damage.\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 DECT handset base. The BMS accepted the cell without triggering error states, and charge current tapered correctly at full capacity across three consecutive cycles.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst charge after installation:\u003c\/strong\u003e\n    Place the handset in the base for a full 16 hours before first use. Ni-MH cells in cordless phones arrive from storage at reduced charge. The slow overnight charge lets the base station's trickle circuit bring each cell to rated voltage evenly before active use.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eTalk time shorter than the original battery after replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH cells do not deliver full rated capacity on the first charge cycle. The electrochemical structure needs three to five full charge-discharge cycles before it reaches 850mAh. If talk time feels short after day one, that is expected behaviour — not a fault. Run the handset until the low-battery indicator triggers, return it to the base for a full 16-hour charge, and repeat for up to five cycles.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBase station showing no-charge or error light after new battery installed\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA Ni-MH pack shipped from storage can sit below 3.0V total — low enough that some DECT base circuits reject the charge handshake. The base reads the voltage, flags it as a fault, and stops pushing current. Remove the handset, leave it out for 30 seconds, then re-seat it firmly in the base cradle. If the error persists, check that the gold contacts on the battery and handset are clean and making full contact — oxidation on those pads breaks the circuit before voltage even registers.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43340110331994,"sku":"BWCS-P104CL-1","price":22.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43340110364762,"sku":"BWCS-P104CL-2","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43340110397530,"sku":"BWCS-P104CL-3","price":27.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-P104CL-1.webp?v=1778367188","url":"https:\/\/batteryweb.com\/products\/gp-gp85aaalh3bxz-replacement-battery-36v-850mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
