It replaces OEM part numbers BT-1009, BT-1009A, 700503110, and BT-1024. Drop this into the handset battery compartment and the handset is ready to charge from the base station.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eAP680BHP-AV, 3920, and DECT D160 compatibility:\u003c\/strong\u003e\n    All three models share the same 2.4V two-cell NiMH pack footprint, connector pinout, and BMS handshake — one battery covers the full range without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack on the AP680BHP-AV base station. The BMS accepted charge on the first dock, temperature stayed within normal range across the full charge cycle, and the handset registered talk-ready status without any error indication.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-charge protocol for NiMH cordless packs:\u003c\/strong\u003e\n    After installing, place the handset in the base cradle and leave it undisturbed for a full 16 hours before first use. NiMH cells at storage voltage will not reach rated 850mAh capacity on a quick top-up — the slow first charge is what sets the cell plates correctly.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eRange drop after a battery swap on the AP680BHP-AV\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eRF transmit power in DECT handsets draws directly from the battery voltage rail. A NiMH pack that shipped at storage charge — typically 2.0–2.1V — cannot sustain the voltage the transmitter needs under RF load. The handset stays connected at close range but drops out progressively further from the base. A full 16-hour base charge restores the pack to its operating voltage band and the range returns to normal.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBase station shows no charge light after installing a new battery\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eAvaya base stations use delta-V detection to confirm a NiMH pack is accepting charge — if the resting voltage is too low from extended storage, the charger circuit does not see a valid response and shows no charge activity. Remove the handset, wait 30 seconds, then re-seat it firmly so both charge contacts close fully. If the light still does not appear, check that the battery terminals are clean and the pack is pushed flush — a partially seated battery breaks contact intermittently.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43340102959194,"sku":"BWCS-P105CL-1","price":21.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43340102991962,"sku":"BWCS-P105CL-2","price":24.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43340103024730,"sku":"BWCS-P105CL-3","price":26.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-P105CL_1.webp?v=1778367188","url":"https:\/\/batteryweb.com\/products\/avaya-ap680bhp-av-replacement-battery-24v-850mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
