It replaces a dead or degraded handset battery that no longer holds a charge. Slot it into the handset battery compartment and return the phone to service.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eCompatible handset models:\u003c\/strong\u003e\n    These models share the same 3.6V three-cell NiMH pack format, connector pin-out, and physical footprint. The base station charges at a fixed trickle rate matched to this voltage and chemistry, so swapping chemistry or voltage would break the charge cycle.\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 DECT handset platform. The BMS accepted charge from the base station cradle without error, and voltage held within the expected window across the full discharge curve.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-install charge requirement:\u003c\/strong\u003e\n    After installing, seat the handset in the base for a full 16-hour charge before first use. NiMH cordless phone batteries shipped in a partial state of charge need that slow first cycle to reach rated capacity — skipping it means the first few calls drain the pack faster than expected.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eTalk time shorter than original battery after replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNiMH cells need three to five full charge-discharge cycles before they hit rated capacity. A new pack out of the box will underperform compared to a broken-in original. Each full cycle conditions the cell chemistry and raises the usable capacity incrementally. By cycle five, the pack should be delivering close to the rated 700mAh.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBase station showing no charge light after new pack installed\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNiMH batteries stored in a warehouse can drop to a voltage level that some base stations treat as a fault condition rather than a depleted pack. The base expects to see a voltage above roughly 3.0V before it begins the charge cycle. If the charge indicator stays off, remove the handset, wait 30 seconds, and re-seat it firmly — this resets the charge detection circuit. If the light still does not come on, check that the battery contacts in the handset are clean and making full contact.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43340081365082,"sku":"BWCS-P501CL-1","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43340081397850,"sku":"BWCS-P501CL-2","price":29.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43340081430618,"sku":"BWCS-P501CL-3","price":32.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-P501CL-1.webp?v=1778367047","url":"https:\/\/batteryweb.com\/products\/sanyo-23621-replacement-battery-36v-700mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
