It replaces OEM part numbers BT-905 and YBT3N600MAH. Use it when the original pack no longer holds a charge or the base station shows a charging fault.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eMPH-6928 series handset fit:\u003c\/strong\u003e\n    These models share the same 3.6V NiMH cell configuration, connector orientation, and BMS handshake with the base station. Swapping to a mismatched voltage or chemistry will trip a charging error at the dock.\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 the MPH-6928 handset. The BMS accepted the charge sequence from the base without fault, and cell voltage held within spec across five full cycles.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-charge conditioning on 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 reach rated 1200mAh capacity only after this slow initial charge — skipping it will leave the pack well short of full capacity 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\"\u003eBase station charging error light on a new NiMH pack\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA new NiMH battery that has been in storage can sit below the voltage threshold the base station uses to confirm a valid pack is present. When the base sees a voltage too low, it flags an error instead of starting the charge cycle. The fix is to briefly power the handset on — this draws enough current to nudge the cell voltage up. Once the resting voltage clears the acceptance window, seat it back in the base and the charge sequence will start normally.\u003c\/p\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 leave storage in a partially discharged state, and fresh packs rarely deliver full rated capacity on the first cycle. Most MPH-series handsets need three to five full charge-discharge cycles before the cells condition to 1200mAh. Run the handset until it drops to low-battery, return it to the base for a complete charge, and repeat. By cycle five, talk time should match the rated capacity.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43340076843098,"sku":"BWCS-P401CL-1","price":22.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43340076875866,"sku":"BWCS-P401CL-2","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43340076908634,"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\/memorex-mph-6928-replacement-battery-36v-1200mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
