It fits the handset compartment directly and restores talk and standby capability when the original cell has degraded. Voltage and capacity match the OEM spec so the base station charges it without modification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eWhy these models share one battery:\u003c\/strong\u003e\n    The 100935, 26936GE2, 29445, and 59519 all run the same 3.6V single-cell NiMH architecture with an identical footprint — 50.79 × 42.40 × 14.23mm. The base station charging circuit targets the same voltage window across this handset family, so one cell covers all of them.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through charge and discharge on NiMH-compatible test equipment. The BMS accepted charge current without tripping, and terminal voltage tracked correctly through the full discharge curve without premature cutoff.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-charge protocol for NiMH cordless handsets:\u003c\/strong\u003e\n    After installing, seat the handset in the base and leave it for a full 16 hours before use. NiMH cordless batteries arrive partially discharged from storage and need a slow first charge to reach rated capacity — cutting this short is the single most common reason a new battery underperforms from day one.\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 battery swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNiMH cells that haven't completed conditioning cycles show a steeper voltage sag under RF transmit load. The DECT radio in these RCA handsets draws a short high-current burst every transmission frame, and a partially conditioned cell can't hold voltage through that spike. When voltage sags below the transmit threshold, the handset either drops range or cuts out entirely. Run three to five full charge-discharge cycles and the cell's internal resistance drops enough to sustain transmit voltage.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBase station shows no-charge or error light with the new battery installed\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA NiMH battery that has sat in storage will arrive at a low resting voltage — sometimes low enough that the base station's charge controller doesn't recognise it as a valid cell. The base reads the voltage, sees it outside its acceptance window, and flags an error instead of starting a charge cycle. Remove the handset, wait 30 seconds, and reseat it firmly so the contacts are fully engaged. If the error persists, the cell voltage may need a brief external boost charge to 3.2V before the base accepts it.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43340080185434,"sku":"BWCS-P501CL-1","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43340080218202,"sku":"BWCS-P501CL-2","price":29.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43340080250970,"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\/rca-100935-replacement-battery-36v-700mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
