When the stock battery stops holding a charge, this is the direct swap that restores the handset to working order. Dimensions are 45.60 x 31.30 x 10.60mm — confirm against the original before fitting.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003e2141CLL handset fit:\u003c\/strong\u003e\n    The 2141CLL runs a 3.6V NiMH cell in the handset bay. This battery matches that voltage rail and physical footprint, so the contacts seat correctly and the handset charges normally in the base station.\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 NiMH-capable test rig. The cell voltage climbed steadily to 3.6V under a controlled charge rate, and the pack held capacity without abnormal heat or voltage drop.\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 for a full 16-hour charge before first use. NiMH cells in cordless phones need that slow initial charge to reach rated capacity — skipping it leaves the battery at 60–70% of its 700mAh potential for the first several uses.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBase station charge light staying off after fitting the new pack\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eA NiMH battery that has sat in storage for months can drop to a resting voltage low enough that some base stations refuse to initiate a charge cycle. The base station's charge controller expects a minimum cell voltage before it switches on current flow. If the light stays off, place the handset in the base for 30 minutes anyway — some controllers will trip on once the pack absorbs a trickle. If the light still does not come on, check the base contacts are clean and the handset is fully seated with no gap at the top of the cradle.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eRange drops noticeably when the handset moves away from the base\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eDECT handsets draw more current during transmission than during standby. If the NiMH pack is not fully conditioned, its internal resistance is higher than normal, and voltage sags under the RF transmit load. That voltage sag reduces transmit power, which the handset reads as a weak signal — cutting range before the battery is actually flat. Run three full charge-discharge cycles and the internal resistance will fall. After cycle three, measure open-circuit voltage after a full charge — it should sit at or above 3.9V before dropping to the 3.6V nominal under load.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43339963334746,"sku":"BWCS-CPJ464CL-1","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43339963367514,"sku":"BWCS-CPJ464CL-2","price":29.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43339963400282,"sku":"BWCS-CPJ464CL-3","price":31.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-CPJ464CL-1.webp?v=1777949695","url":"https:\/\/batteryweb.com\/products\/american-2141cll-replacement-battery-36v-700mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
