It fits the Verve 500, Verve 500 SMS, Verve 500 Black, and Verve 500 Red handsets. Dimensions are 50.00 × 30.50 × 4.20mm — match these against your existing cell before installing.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eVerve 500 handset compatibility:\u003c\/strong\u003e\n    All four Verve 500 variants share the same handset chassis and battery bay dimensions. The 3.7V rail and connector pinout are identical across the range, so one cell covers the full lineup 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 the Verve 500 platform. The BMS held a stable 3.7V nominal during discharge and accepted a standard Li-ion charge curve without triggering protection cutoff.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-charge procedure for Verve 500:\u003c\/strong\u003e\n    After fitting this cell, seat the handset in the base and leave it undisturbed for a full charge cycle before making calls. Li-ion cells shipped in storage state need one complete charge to calibrate the handset's charge indicator accurately.\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\"\u003eA fresh Li-ion cell ships at partial state of charge — typically 30–50%. The handset's fuel gauge calibrates against the first few full cycles. Until two or three complete charge-discharge cycles have run, the displayed battery level and actual talk time will not align. Run the handset down to low-battery warning, then charge fully, twice over. By the third cycle, capacity readings stabilise at rated 600mAh.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBase station charge light not activating on new battery\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eWhen a Li-ion cell arrives deeply discharged from storage, the base station's charge circuit may not detect a valid battery voltage and will not start the charge cycle. Remove the handset, wait 10 seconds, and reseat it firmly — poor contact at the charging pins is the first thing to rule out. If the light still does not activate, check the cell voltage directly; it should read at least 3.0V. Below that threshold, the base treats the pack as faulty and refuses to charge until voltage is recovered with a bench charger or USB emergency charge port if the handset supports it.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43340033228890,"sku":"BWCS-BVE500CL-1","price":22.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43340033261658,"sku":"BWCS-BVE500CL-2","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43340033294426,"sku":"BWCS-BVE500CL-3","price":27.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-BVE500CL-1.webp?v=1778367024","url":"https:\/\/batteryweb.com\/products\/bti-verve-500-replacement-battery-37v-600mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
