It replaces OEM part 5M702BMXZ and fits directly into the battery compartment on both models. The cell dimensions are 35.40 × 32.50 × 6.70mm.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eVerve 410 and 450 compatibility:\u003c\/strong\u003e\n    Both handsets share the same battery bay dimensions, connector polarity, and 2.4V charging circuit. A single cell format covers both models without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this battery through charge and discharge on a DECT handset base station. The NiMH pack accepted charge normally, the base station indicator moved to full charge status, and voltage held steady under RF transmit load.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst charge on a NiMH cordless handset:\u003c\/strong\u003e\n    After fitting, place the handset in the base and leave it for a full 16 hours before first use. NiMH cells arrive from storage partially discharged, and the slow first charge lets the pack reach its rated 600mAh capacity properly.\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 expected after fitting a new NiMH pack\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNiMH cells do not reach full rated capacity on the first cycle. The chemistry requires three to five full charge-discharge cycles before the cell stabilises at 600mAh. Until then, talk time will be noticeably shorter than the original battery at its best. Run the handset down fully, return it to the base for a complete charge, and repeat — capacity increases with each cycle.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBase station charge light not activating after battery swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA NiMH pack that has sat in storage can drop below the voltage threshold the base station uses to detect a valid cell. If the base shows no charge activity or an error light, the handset is likely reading the low resting voltage as a fault. Remove the handset, wait 10 seconds, and reseat it firmly so the contacts align. If the base still does not respond, check the resting voltage across the battery terminals — it should read at least 2.0V to trigger normal charging.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43340098306138,"sku":"BWCS-SDT500CL-1","price":21.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 2 Year","offer_id":43340098338906,"sku":"BWCS-SDT500CL-2","price":24.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 3 Year","offer_id":43340098371674,"sku":"BWCS-SDT500CL-3","price":26.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-SDT500CL-1.webp?v=1778367188","url":"https:\/\/batteryweb.com\/products\/british-telecom-verve-410-replacement-battery-24v-600mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
