It replaces the original rechargeable pack when the handset stops holding a charge or loses talk time. Dimensions are 50.43 x 42.54 x 14.40mm — confirm these against your existing battery before ordering.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eBroad Sanyo handset compatibility:\u003c\/strong\u003e\n    These models share the same 3.6V three-cell Ni-MH configuration, connector orientation, and physical footprint, which is why a single pack covers the full range. The cell arrangement is AA-format, so voltage delivery matches the base station's charge circuit without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this pack through charge and discharge cycles on a compatible handset base. The charging circuit accepted the battery immediately, and the BMS held steady through RF transmit load without triggering a cutoff.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst charge on Ni-MH cordless handsets:\u003c\/strong\u003e\n    After installing, seat the handset in the base and leave it for a full 16 hours before first use. Ni-MH cells in cordless phones arrive partially discharged from storage — skipping the slow initial charge leaves usable capacity on the table for the first several cycles.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eRange reduction under RF load with a new Ni-MH pack\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eWhen a Ni-MH cell is under-conditioned or sitting below full capacity, the transmit burst drawn by the DECT radio causes a brief voltage sag. That sag can drop output power enough to shorten effective range, even if the battery reads as charged. The issue is most noticeable in the first three to five cycles after installation. Running the pack through several full charge-and-use cycles brings internal resistance down and stabilises voltage under RF load.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBase station charge light stays off or shows error after swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eSanyo base stations use a delta-V detection method to confirm a Ni-MH pack is present and accepting charge. A battery that has discharged below the base's acceptance threshold during storage may not trigger that detection, so the charge indicator never lights. Remove the handset, leave it out of the base for 30 seconds, then re-seat it firmly. If the error persists, apply a trickle charge by leaving the handset docked overnight — most base stations will recover a deeply discharged pack within 12–16 hours and resume normal charge indication once voltage climbs above 3.0V.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43340029853786,"sku":"BWCS-P502CL-1","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43340029886554,"sku":"BWCS-P502CL-2","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43340029919322,"sku":"BWCS-P502CL-3","price":28.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-P502CL_1.webp?v=1778367047","url":"https:\/\/batteryweb.com\/products\/sanyo-23620-replacement-battery-36v-1200mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
