It replaces OEM part numbers GES-PCH01 and 3N270AA. The voltage, cell format, and connector match the original battery exactly.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eCAS and 23616 series compatibility:\u003c\/strong\u003e\n    These handsets share a common 3.6V single-row NiMH bay with identical connector pitch and polarity. The base station charges at a fixed trickle rate matched to this cell size, so swapping to a different voltage or chemistry will cause charge errors.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through the base station charge circuit and confirmed the BMS accepted charge without triggering an error light. Discharge curves stayed flat through normal handset draw.\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 cordless phone batteries need a slow initial charge to reach rated capacity — skipping this leaves cells partially formed and talk time noticeably shorter.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eRange dropping mid-call after a new NiMH pack is installed\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eDECT handsets ramp transmit power to maintain link quality. When a NiMH pack hasn't been through conditioning cycles, its internal resistance is higher than a fully formed cell. Under RF transmit load, voltage sags — the handset pulls back power to protect the circuit, and range shrinks. This is not a faulty battery. Run three to five full charge-and-use cycles through the base station, and internal resistance drops to spec. Range stabilises once the cells are properly conditioned.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBase station charge light not activating with the new battery seated\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNiMH batteries lose charge during storage, and some Sanyo base stations use a voltage-sensing circuit that won't initiate a charge cycle if the pack reads below roughly 3.0V. The base sees a low-voltage pack as a fault condition rather than a depleted cell. To reset this, hold the handset in the cradle for 30 minutes — the base trickles a small current that brings voltage up to the acceptance threshold. Once the pack reaches that threshold, the charge indicator activates and the full cycle begins normally.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43340110626906,"sku":"BWCS-P302CL-1","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43340110659674,"sku":"BWCS-P302CL-2","price":28.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43340110692442,"sku":"BWCS-P302CL-3","price":31.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-P302CL_1.webp?v=1778367188","url":"https:\/\/batteryweb.com\/products\/sanyo-23616-replacement-battery-36v-600mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
