It slots directly into the handset battery compartment and restores talk and standby time when the original cell has degraded. Dimensions are 50.56 x 49.73 x 6.37mm — confirm these against your existing pack before ordering.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eDECT Line 660, 670, and 750 compatibility:\u003c\/strong\u003e\n    All three handsets share the same 3.6V single-cell Ni-MH battery form factor, identical connector orientation, and matching physical footprint — that is why one part covers the full trio.\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 the base station. The Ni-MH cells accepted charge from a cold state, the base station charging indicator responded correctly, and voltage held steady through standby draw.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst charge on a new Ni-MH pack:\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 cordless phone batteries arrive partially discharged from storage — a slow initial charge is what brings them to rated capacity, not a quick top-up.\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\n  \u003cp class=\"bpw-desc-p\"\u003eNew Ni-MH cells do not deliver rated capacity on the first cycle. The chemistry needs three to five full charge-discharge cycles before the cells reach 750mAh. Each cycle, talk time will noticeably increase. If talk time is still short after five complete cycles, check that the handset is fully seated in the base — a poor cradle contact reduces charge current and the pack never reaches full voltage.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBase station showing no charge or error light after swapping the battery\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH packs can sit in warehouse storage for months and drop below the voltage threshold the base station expects before it starts charging. The base sees a voltage that looks like a fault rather than a depleted cell. To recover it, remove the battery, let it sit at room temperature for 30 minutes, then reinstall and reseat the handset firmly. If the base still shows an error, measure the battery terminals — anything below 3.0V means the cells need a trickle pre-charge before the base will accept them.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43340004196442,"sku":"BWCS-BMS687CL-1","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43340004229210,"sku":"BWCS-BMS687CL-2","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43340004261978,"sku":"BWCS-BMS687CL-3","price":29.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-BMS687CL-1.webp?v=1778367023","url":"https:\/\/batteryweb.com\/products\/tiptel-dect-line-660-replacement-battery-36v-750mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
