It slots into the handset battery compartment and powers both RF transmission and standby. Capacity is rated at 4.32Wh, matching the original specification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eMPH-series handset compatibility:\u003c\/strong\u003e\n    These Bell South handsets share a common 3.6V NiMH cell format, the same connector orientation, and a matching BMS handshake threshold — which is why one battery covers the full MPH lineup without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack on the MPH6928 platform and confirmed the base station accepted the charge circuit without error. The BMS held voltage above the 3.2V low-cutoff under sustained RF load across multiple discharge cycles.\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 and leave it for a full 16 hours before first use. NiMH cells in cordless phones need a slow initial charge to reach rated capacity — a short first charge will leave you with noticeably less talk time from cycle one.\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\"\u003eNiMH cells ship in a partial state of discharge and need three to five full charge-discharge cycles before they reach rated capacity. On cycle one, you may see significantly less talk time than expected — this is normal cell behaviour, not a fault. Run the handset down until it signals low battery, return it to the base for a full charge, and repeat. By cycle four or five, capacity stabilises at the rated 1200mAh.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBase station showing no charge or error light after fitting new pack\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA NiMH battery stored for several months can drop to a voltage level the base station interprets as a fault rather than a depleted cell. The base's charge controller checks for a minimum acceptance voltage before it starts the charge cycle. If the indicator stays red or unlit, remove the handset, wait 30 seconds, and reseat it firmly — this resets the charge controller's detection routine. If the error persists, the cell voltage has dropped below recovery threshold; try a trickle charge using a compatible external NiMH charger at 0.1C until the pack reads above 3.0V, then return it to the base.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43340076744794,"sku":"BWCS-P401CL-1","price":22.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43340076777562,"sku":"BWCS-P401CL-2","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43340076810330,"sku":"BWCS-P401CL-3","price":27.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-P401CL-1.webp?v=1778367047","url":"https:\/\/batteryweb.com\/products\/bell-south-mph6928-replacement-battery-36v-1200mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
