It matches the OEM dimensions at 31.54 × 25.13 × 3.95mm, so it seats flush in the battery bay without modification. The part numbers S30852-D2240-X1, V30145-K1310-X448, F39033-V328-C901, and V30145-K1310-X458 all cross-reference to this cell.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eGigaset L410 and Maxwell platform fit:\u003c\/strong\u003e\n    These models share the same battery bay dimensions, 3.7V Li-ion voltage rail, and connector pinout. One cell covers the full range without any wiring or adapter work.\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 L410 handset and confirmed the BMS handshake with the base station charging circuit. The cell accepted charge normally and the handset registered a full charge state without error flags.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst charge on the Gigaset L410:\u003c\/strong\u003e\n    After installing, seat the handset in the base and leave it undisturbed for a full charge cycle before making any calls. The L410 base delivers a slow trickle charge — interrupting it early on a new cell reduces the usable capacity from the first cycle.\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\"\u003eA new Li-ion cell in the Gigaset L410 does not always reach full rated capacity on the first charge. The cell ships in a partial state of charge, and the first few full charge-discharge cycles are needed to condition the electrodes to their working capacity. If talk time feels short in the first week, complete three to five full charge cycles — charge until the base shows full, then use the handset until the low battery warning triggers. After conditioning, the cell should stabilise at its rated 250mAh output.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBase station shows no charge or error light after fitting new battery\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eIf the base station's charge indicator stays dark or shows an error after you install this battery, the cell voltage has likely dropped below the base's acceptance threshold during storage. The Gigaset base charging circuit checks for a minimum input voltage before enabling the charge current — a deeply discharged cell can read too low to trigger it. Remove the handset from the base, wait 30 seconds, then reseat it firmly to reset the charge detection cycle. If the indicator still does not respond, check that the handset contacts are clean and making full contact with the base cradle pins.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43339935842394,"sku":"BWCS-SIL410CL-1","price":22.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43339935875162,"sku":"BWCS-SIL410CL-2","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43339935907930,"sku":"BWCS-SIL410CL-3","price":27.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-SIL410CL-1.webp?v=1778367002","url":"https:\/\/batteryweb.com\/products\/siemens-gigaset-l410-replacement-battery-37v-250mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
