It replaces the original rechargeable cell that powers the handset between charges. No OEM part number exists for this pack — it matches by voltage, capacity, connector, and physical footprint.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003e18560 and GESPC910 compatibility:\u003c\/strong\u003e\n    Both handsets run on the same 3.6V single-cell Ni-MH rail and share an identical connector pinout and cell housing. One battery pack covers both models.\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 Ni-MH compatible charger. The BMS accepted current correctly and voltage held steady at 3.6V nominal under simulated talk load.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-charge protocol for Ni-MH cordless packs:\u003c\/strong\u003e\n    After installing, seat the handset in the base and leave it for a full 16 hours before the first use. Ni-MH cells fresh from storage are partially discharged — skipping the slow first charge will cap the pack below 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\"\u003eTalk time shorter than the original battery after replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH cells need three to five full charge-discharge cycles to reach rated capacity. A new pack installed and used immediately will underperform — the crystalline structure in the cells hasn't fully formed yet. Run the handset down to the low-battery beep, then return it to the base for a full charge. Repeat this three times and talk time will step up noticeably each cycle.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBase station shows no charge light or error after swapping the battery\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eSanyo cordless bases use a voltage threshold to detect a handset battery — if the pack voltage sits too low after storage, the base won't initiate a charge cycle. A Ni-MH pack can drop to around 3.0V or below in storage. Connect the handset to a standalone Ni-MH charger first to bring the pack above 3.2V, then seat it back in the base — the base should recognise the pack and begin charging normally.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43339941707866,"sku":"BWCS-BP901CL-1","price":27.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43339941740634,"sku":"BWCS-BP901CL-2","price":31.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43339941773402,"sku":"BWCS-BP901CL-3","price":34.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-BP901CL_1.webp?v=1778366983","url":"https:\/\/batteryweb.com\/products\/sanyo-18560-replacement-battery-36v-1500mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
