It fits both the KXFG2451 and KX-FG2451 handset variants. Voltage and cell chemistry match the base station's charging circuit exactly.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eKXFG2451 \/ KX-FG2451 handset fit:\u003c\/strong\u003e\n    Both model designations use the same handset chassis, battery bay dimensions, and 2.4V dual-cell Ni-MH charging circuit. One pack covers both.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through the KX-FG2451 base station charger and confirmed the BMS accepted the charge without triggering an error light. Voltage recovery from storage discharge reached nominal levels within the first two full cycles.\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 call. Ni-MH cells in cordless phones need a slow initial charge to reach rated capacity — skipping this shortens effective talk time 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\"\u003eNew Ni-MH cells ship in a partially discharged state and need three to five full charge-and-use cycles before they reach rated capacity. On the first cycle, talk time will feel noticeably shorter than expected — this is normal cell behaviour, not a fault. Each subsequent full cycle conditions the cells further. By cycle five, capacity should be at or near the 850mAh rating.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBase station shows no charge or error light with new pack installed\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH batteries drop below 2.0V during extended storage, and some base stations refuse to charge packs below their acceptance threshold. Remove the handset, wait 30 seconds, then reseat it firmly — the charging contacts need a clean connection to restart the charge cycle. If the error light persists, check that the contacts on both the handset and base are free of debris. A pack that registers at or above 1.8V on a multimeter will recover with a standard charge cycle once contact is confirmed.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43340102533210,"sku":"BWCS-P105CL-1","price":21.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43340102565978,"sku":"BWCS-P105CL-2","price":24.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43340102598746,"sku":"BWCS-P105CL-3","price":26.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-P105CL_1.webp?v=1778367188","url":"https:\/\/batteryweb.com\/products\/muraphone-kxfg2451-replacement-battery-24v-850mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
