The V-2200 is a compact portable medical unit, and this cell matches the original's voltage rail, chemistry, and form factor at 18.80 x 16.80 x 16.00mm. Swap it when the original cell no longer holds charge or triggers persistent low-battery alerts.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eV-2200 platform fit:\u003c\/strong\u003e\n    The V-2200 uses a tightly regulated 3.6V Ni-MH chemistry. The BMS is calibrated to that specific voltage curve and will reject cells outside the expected charge profile. This replacement matches both the chemistry and the physical connector footprint to satisfy those handshake requirements.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through full charge and discharge on a medical-grade battery analyser. The BMS accepted the cell without fault flags, and the charge IC brought the cell to full capacity without triggering an over-voltage cutoff.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-installation self-test cycle:\u003c\/strong\u003e\n    After fitting this cell, allow the V-2200 to complete its full power-on self-test without interruption. The device runs a BMS verification routine at startup — breaking power mid-sequence logs a false battery fault that persists until the next clean 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 V-2200 charge indicator stalls below 100% on the first charge\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe V-2200's charge IC applies a conservative current limit when it detects a new or previously depleted Ni-MH cell. This is intentional — the controller is protecting against overcharge on a cell whose internal resistance it hasn't yet mapped. On the first cycle, the charge indicator may plateau at 80–90% for an extended period before climbing to full. This is not a fault. Complete one full charge-discharge cycle and the controller recalibrates its end-of-charge detection to the cell's actual capacity.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eDevice not powering on after the replacement cell sat in storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH cells self-discharge in storage — at 3.6V nominal, a depleted cell can drop below the BMS recovery threshold, typically around 2.8V per cell, causing the device to refuse to boot. The BMS interprets this voltage as a damaged or absent pack. Place the cell on charge for a minimum of four hours before attempting to power on the V-2200. If the device still does not boot, confirm the charger output is delivering current — a cell voltage below 1.0V per cell may require a manual trickle pre-charge before the BMS will engage.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381370388570,"sku":"BWCS-ATV220MD-1","price":36.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381370421338,"sku":"BWCS-ATV220MD-2","price":42.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381370454106,"sku":"BWCS-ATV220MD-3","price":47.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-ATV220MD-1.webp?v=1778900351","url":"https:\/\/batteryweb.com\/products\/atoms-v-2200-replacement-battery-36v-80mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
