It fits the Silver, Silver Reciproc, and SR2634 platforms, as well as devices carrying model number V0411630000000. Capacity is rated at 12Wh — use the figure in the product data, not estimates from other sources.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eSilver and Silver Reciproc compatibility:\u003c\/strong\u003e\n    Both platforms share the same 6V cell architecture, connector pinout, and BMS handshake protocol. Swapping between them does not require a different cell — the same GP210AAHCB5BMXZ pack satisfies both device BMS requirements.\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 Silver platform and confirmed stable BMS communication throughout. The protection circuit responded correctly to end-of-discharge cutoff without triggering a false fault.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-swap self-test protocol:\u003c\/strong\u003e\n    After installing this battery, allow the handpiece to complete its full power-on self-test without interruption. The device BMS runs a chemistry verification sequence at startup — interrupting it mid-cycle registers a false battery fault that persists until the next complete reboot.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the Silver handpiece shows a low-battery alarm immediately after a confirmed full charge\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe VDW Silver BMS sets its pass threshold based on the charge signature of the original OEM cell chemistry. A new replacement cell has not yet established the voltage curve the BMS expects on its first cycle. The device reads this unfamiliar profile as a marginal or undercharged state and triggers the alarm even at full capacity. Run one complete charge-discharge cycle before clinical use — after that, the BMS learns the new cell's curve and the alarm clears.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eHandpiece will not power on after the battery sat in storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH cells self-discharge during storage. If the pack drops below the BMS recovery threshold — typically around 4.5V for a 6V pack — the device protection circuit blocks the power-on sequence entirely. This is not a dead cell; it is a deep-discharge lock. Place the battery on charge and leave it connected for a full cycle without attempting to power on the device. Once the pack climbs back above the recovery threshold, normal startup resumes.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381459419226,"sku":"BWCS-VDS263MD-1","price":35.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381459451994,"sku":"BWCS-VDS263MD-2","price":41.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381459484762,"sku":"BWCS-VDS263MD-3","price":45.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-VDS263MD-1.webp?v=1778901015","url":"https:\/\/batteryweb.com\/products\/vdw-silver-replacement-battery-6v-2000mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
