It replaces the original pack when talk time has dropped or the handset no longer holds a charge. Dimensions are 50.43 × 42.54 × 14.40mm — verify your existing battery matches before ordering.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eP0871365 handset fit:\u003c\/strong\u003e\n    The P0871365 uses a 3.6V three-cell Ni-MH pack to power the DECT radio and baseband processor on the same voltage rail. Swapping to a different voltage or chemistry will cause charging faults or handset shutdowns.\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 Ni-MH compatible charger and confirmed the BMS accepted full charge without thermal flag or cutoff error.

Ni-MH cells shipped in storage state need a slow initial charge to reach rated capacity — skipping this step will leave you with noticeably short talk time from the start.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBase station showing no charge light after fitting a new Ni-MH pack\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH packs drop to around 3.0V or lower during storage. Some Nortel bases use a voltage threshold check before starting the charge cycle — if the pack comes in below that floor, the base treats it as a fault and shows no charge indicator. The fix is a short external boost charge using a standalone Ni-MH charger to bring the pack above 3.3V, then reseat in the base. After that, the base charge circuit accepts it normally and the charge light activates.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eRange dropping mid-call after a battery swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eDECT handsets increase transmit power when signal weakens, which pulls harder from the battery. A Ni-MH pack in its first few cycles has not yet reached full capacity, so voltage sags under that RF load and the handset pulls back transmit power to protect itself — cutting effective range. This resolves after three to five full charge-discharge cycles, which condition the cells to rated capacity. If range is still short after five cycles, measure resting voltage: a healthy pack should read at least 3.6V off the charger.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43340029362266,"sku":"BWCS-P502CL-1","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43340029395034,"sku":"BWCS-P502CL-2","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43340029427802,"sku":"BWCS-P502CL-3","price":28.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-P502CL_1.webp?v=1778367047","url":"https:\/\/batteryweb.com\/products\/nortel-p0871365-replacement-battery-36v-1200mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
