It matches OEM part numbers A0548446, BPN100, NTTQ69BA, NTTQ4050, and PTE110. The cell fits directly into the handset battery compartment with no modification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003e3616, 3620, and NetLink h340 compatibility:\u003c\/strong\u003e\n    All three handsets run the same 3.6V single-cell NiMH rail with an identical footprint and connector orientation. One battery part number covers the full group because the BMS thresholds and charge termination voltage are shared across the platform.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack in a 3616 handset and confirmed the base station accepted charge initiation without a fault light. The BMS reached full termination voltage cleanly across five consecutive cycles.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-charge protocol for NiMH handsets:\u003c\/strong\u003e\n    After installing, seat the handset in the base and leave it for a full 16 hours before taking the first call. NiMH cells shipped from storage need a slow initial charge to align all cells to rated capacity — skipping this shortens effective talk time from the first use.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eRange dropping on the 3616 after a battery swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe 3616 DECT radio draws a short burst of higher current every time it transmits to the base. A NiMH cell that hasn't completed conditioning cycles shows a voltage sag under that RF transmit load. When the cell voltage dips below the radio's minimum threshold, the handset reduces transmit power or drops frames. Running three to five full charge-discharge cycles brings internal resistance down and eliminates the sag.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eHandset not pairing with the base after battery replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eRemoving the battery completely cuts power to the handset's DECT registration memory on some firmware versions. When power returns, the handset boots without stored pairing data and the base ignores its subscription request. To re-pair, hold the handset's Find\/Page button on the base for five seconds until the base enters registration mode, then follow the on-screen prompt on the handset. Once re-registered, pairing is stored in non-volatile memory and survives future battery swaps.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43339924078682,"sku":"BWCS-BPE110CL-1","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43339924111450,"sku":"BWCS-BPE110CL-2","price":27.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43339924144218,"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\/avaya-3616-replacement-battery-36v-700mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
