It replaces OEM part numbers L50645-K1310-X363, V30145-K1310-X363, and V30145-K1310-X453. When the original cell degrades, talk time and standby drop sharply — this battery restores both.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eGigaset M2 and M3 platform fit:\u003c\/strong\u003e\n    These models share the same 3.7V Li-ion cell format, connector pinout, and BMS handshake, which is why one battery covers the full range — M2, M2 Plus, M3, and OpenStage M3 Plus — without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell in a Gigaset M3 handset. The base station accepted the charge immediately, the BMS passed the voltage check on first seat, and the handset registered full signal strength at the display.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-seat charge on DECT handsets:\u003c\/strong\u003e\n    After fitting this battery, seat the handset in the base and leave it for a full 16 hours before the first call. Li-ion cells shipped in storage mode may present a voltage the base interprets as fault — a full slow charge clears this and brings the cell to rated capacity.\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 rated after replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA new Li-ion cell ships partially discharged. If the handset goes straight into use, the battery never reaches full charge in one sitting and the first few cycles appear short. Place the handset in the base undisturbed for 16 hours, then run it to low before reseating. After two or three full cycles, the cell reaches its rated 650mAh and talk time stabilises.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBase station not charging after battery swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eIf the base shows no charge activity or an error light after fitting a new battery, the cell voltage has likely dropped below the base station's acceptance threshold during storage. Remove the handset, reseat it firmly, and leave it connected for at least 30 minutes without lifting it. The base will begin trickle-charging once the BMS presents a voltage above 3.0V — at that point, normal charge resumes automatically.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43339906187354,"sku":"BWCS-SXM20CL-1","price":22.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43339906220122,"sku":"BWCS-SXM20CL-2","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43339906252890,"sku":"BWCS-SXM20CL-3","price":27.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-SXM20CL-1.webp?v=1778366945","url":"https:\/\/batteryweb.com\/products\/siemens-gigaset-m2-replacement-battery-37v-650mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
