It fits the Gigaset 905, 920, 951, 952, and several related models that share the same battery bay dimensions and voltage rail. Capacity is 4.32Wh — matching the original specification from the product data.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eGigaset 905 \/ 920 \/ 951 \/ 952 shared battery platform:\u003c\/strong\u003e\n    These handsets use the same 3.6V NiMH cell configuration, identical connector orientation, and matching physical footprint (52.99 × 44.48 × 15.15mm). One battery SKU covers the full range without modification.\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 a Gigaset handset base station. The BMS accepted the NiMH voltage curve from the first charge cycle, and the base station charge indicator lit correctly without fault codes.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-charge protocol for Gigaset NiMH packs:\u003c\/strong\u003e\n    After installing, seat the handset in the base and leave it for a full 16 hours before use. NiMH cells shipped from storage have partial charge — skipping this step cuts into the first few cycles and the pack never fully recovers 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 battery swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNiMH cells need three to five full charge-discharge cycles before they hit rated capacity. A pack pulled straight from storage and used immediately will underperform — this is normal cell behaviour, not a fault. Each subsequent full cycle reconditions the cells and capacity climbs. By cycle five, the pack should be delivering close to the rated 1200mAh.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBase station shows no charge light after fitting new pack\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNiMH batteries sit in storage for months before sale, and the cell voltage can drop below the threshold the Gigaset base station uses to detect a valid battery. When voltage is too low, the base reads the pack as absent or faulty and withholds charging current. Remove the handset, wait 30 seconds, reseat it firmly, and hold it in place for two minutes — contact pressure matters on these units. If the charge light still does not appear, check the base contacts for oxidation and clean with a dry cloth before trying again.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43340077432922,"sku":"BWCS-SIG920CL-1","price":27.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43340077465690,"sku":"BWCS-SIG920CL-2","price":31.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43340077498458,"sku":"BWCS-SIG920CL-3","price":34.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-SIG920CL_1.webp?v=1778367047","url":"https:\/\/batteryweb.com\/products\/siemens-gigaset-905-replacement-battery-36v-1200mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
