It matches the original voltage, capacity, and connector to restore normal handset operation. Cross-references include OEM part numbers A0548446, BPN100, NTTQ69BA, and NTTQ4050.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003ePolycom 8002 and NetLink h340 compatibility:\u003c\/strong\u003e\n    These handsets share the same 3.6V single-cell NiMH architecture, connector pinout, and BMS handshake with the base station. One pack covers the full range of affected models without modification.\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 the 8002 platform. The BMS accepted the cell voltage on first insertion, and the base station registered an active charge state without error flags across all test units.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-charge protocol for NiMH cordless packs:\u003c\/strong\u003e\n    After installing, seat the handset in the base and leave it for a full 16 hours before first use. NiMH cells in standby storage arrive partially discharged — a slow initial charge is what allows them to reach their rated 700mAh capacity. Skipping this step is the single most common cause of short talk time on new replacements.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eRange dropping off after installing a new NiMH pack\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Polycom 8002 transmitter draws a short current spike when maintaining DECT signal at range. A NiMH cell that hasn't completed its first full conditioning cycle has higher internal resistance than a broken-in pack. That resistance causes voltage to sag under the RF load, which the handset interprets as low battery and reduces transmit power. Run three to five full charge-discharge cycles and the internal resistance drops — range returns to normal.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBase station shows no charge activity or error light after swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNiMH packs stored before shipping can sit below 3.0V. Some Polycom base stations check for a minimum voltage before opening the charge circuit — if the cell arrives too low, the base reads it as a fault and refuses to charge. Remove the handset, wait 30 seconds, and re-seat it firmly so the contacts reset. If the base still shows no activity, use a USB NiMH trickle charger to bring the cell above 3.2V, then return it to the base — the charge circuit will accept it from that point.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43339924176986,"sku":"BWCS-BPE110CL-1","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43339924209754,"sku":"BWCS-BPE110CL-2","price":27.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43339924242522,"sku":"BWCS-BPE110CL-3","price":29.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-BPE110CL-1.webp?v=1778366982","url":"https:\/\/batteryweb.com\/products\/polycom-8002-replacement-battery-36v-700mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
