It fits the Verve 450, Verve 450 SMS, Verve 450 black, and Verve 450 red, along with twelve additional variants in the same handset family. When the original pack stops holding a charge, this unit restores the handset to full operation.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eVerve 450 handset family fit:\u003c\/strong\u003e\n    All Verve 450 variants share the same 2.4V cell configuration, connector pinout, and physical footprint. One pack 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 ran this pack through charge and discharge cycles on a Verve 450 base station. The BMS accepted charge within the base's voltage window on the first cycle and flagged charge completion correctly on the handset indicator.\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 for a continuous 16-hour charge before first use. Ni-MH cells in cordless phones ship in a partially discharged state. Skipping the slow initial charge leaves the cells below rated capacity and the shortfall compounds over early cycles.\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\"\u003eNi-MH cells don't reach full rated capacity on the first charge cycle — this is normal chemistry, not a faulty unit. Capacity builds across three to five full charge and discharge cycles as the cell plates condition. If talk time is still noticeably short after five cycles, check that the handset is making clean contact with the base charging pins. Dirty or bent pins drop charge current and the pack never reaches a full state of charge, which the handset reads as low capacity.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBase station shows no charge light or error indicator after battery swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH batteries discharge slowly during storage. If the pack voltage drops far enough, the Verve 450 base station won't recognise it as a valid battery and withholds charging current — the charge indicator stays off or shows an error. Remove the handset, wait 10 seconds, and reseat it firmly. If the base still won't accept the pack, try a different power outlet to rule out a low-voltage supply issue. Once the base begins charging, leave the handset undisturbed for the full 16-hour initial cycle so the pack rises above the base's acceptance threshold and stays there.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43340100239450,"sku":"BWCS-SDT500CL-1","price":21.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 2 Year","offer_id":43340100272218,"sku":"BWCS-SDT500CL-2","price":24.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 3 Year","offer_id":43340100304986,"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\/bti-verve-450-replacement-battery-24v-600mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
