It replaces the original pack when the handset no longer holds a usable charge through a full call or standby period. Dimensions are 52.99 x 44.48 x 15.15mm — verify against your existing pack before ordering.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eHW9012 \/ HW1940 series fit:\u003c\/strong\u003e\n    These three models share the same handset chassis, battery bay dimensions, and connector orientation — one pack covers all three 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 DECT handset rig. The BMS accepted the Ni-MH voltage curve without tripping a charge fault, and cell balance held across five full cycles.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-charge protocol for Ni-MH handsets:\u003c\/strong\u003e\n    After installing, seat the handset in the base and leave it for a full 16 hours before first use. Ni-MH cells in cordless phones reach rated capacity only after a slow initial charge — skipping this step reduces the charge your pack will accept long-term.\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 original battery after replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH cells do not ship at full capacity. Out of the box, a new pack typically delivers 60–70% of its rated 1200mAh on the first cycle. Each full charge-discharge cycle conditions the cells further. By cycle three to five, capacity stabilises at its rated value — do not judge the pack before completing at least five full cycles.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBase station showing no charge or error light after swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH batteries discharged during storage can measure below the voltage threshold the base uses to confirm a valid pack is seated. Some Gigaset-platform bases reject packs that read under approximately 3.0V at the contacts. Remove the handset, reinsert it firmly, and leave it on the base for 30 minutes — the trickle charge stage brings the cell voltage up to the acceptance window. If the error persists, check the contact pins on the handset for oxidation and clean with a dry cloth.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43340077629530,"sku":"BWCS-SIG920CL-1","price":27.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43340077662298,"sku":"BWCS-SIG920CL-2","price":31.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43340077695066,"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\/hoft-wessel-hw9012-replacement-battery-36v-1200mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
