It also fits the C4065R and FC1 models sharing the same battery bay and connector. OEM part numbers covered include 4.999.046.235, 4999046235, NTTQ49MAE6, and 4.999.134.298.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eTenovis Integral D3 Mobile, C4065R, and FC1 compatibility:\u003c\/strong\u003e\n    These three handsets share the same 2.4V Ni-MH cell format, connector pinout, and BMS handshake with the base station charging circuit — one battery pack covers all three.\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 Tenovis-compatible base. The BMS accepted the NiMH voltage profile without fault, and the charging circuit terminated correctly at full capacity.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst charge after installation:\u003c\/strong\u003e\n    After fitting this battery, seat the handset in the base for a full 16 hours before use. NiMH cells in cordless phones arrive partially discharged from storage — skipping the slow first charge leaves the pack well below its 600mAh rated capacity 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 or error light after fitting a new NiMH pack\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eWhen a NiMH battery sits in storage for several months, its resting voltage drops significantly — sometimes below the minimum acceptance threshold the Tenovis base expects before starting a charge cycle. The base reads this low voltage as a fault rather than an empty battery. To recover, remove the handset from the base for 30 seconds, then reseat it firmly. If the base still shows an error, leave the handset seated for 10–15 minutes — most Tenovis base stations switch to a trickle pre-charge mode and begin accepting the pack once it reads above approximately 2.0V.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eRange drops noticeably when the new battery nears the bottom of its charge\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eDECT handsets draw higher current during RF transmission bursts, and a low NiMH pack sags in voltage under that load. The Tenovis D3 Mobile's transmit circuit needs a stable supply — when voltage sags, the radio reduces output power to protect the circuit, cutting usable range. This is more pronounced in the first three to five charge cycles before the NiMH cells reach full capacity. Charge the handset fully and complete several conditioning cycles before assessing actual range performance.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43339961532506,"sku":"BWCS-AYD3CL-1","price":21.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43339961565274,"sku":"BWCS-AYD3CL-2","price":24.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43339961598042,"sku":"BWCS-AYD3CL-3","price":26.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-AYD3CL-1.webp?v=1778366983","url":"https:\/\/batteryweb.com\/products\/avaya-tenovis-integral-d3-mobile-replacement-battery-24v-600mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
