Both models share the same battery bay geometry, connector, and BMS handshake protocol. Swap it when the original cell no longer holds a useful charge between recharge cycles.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eDS-MH611 and iDS-TCO100F compatibility:\u003c\/strong\u003e\n    Both cameras run the same 3.7V power rail, use an identical physical bay at 46 × 34 × 5.60mm, and negotiate charge state through the same BMS communication layer — so one cell covers both units without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran the DV-02 cell through charge, discharge, and motion-trigger cycles. The BMS held cutoff correctly at low-voltage threshold and accepted a full charge without thermal event. IR LED activation during night-vision draw did not trip the protection circuit.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-install power cycle:\u003c\/strong\u003e\n    After fitting this cell, power cycle the camera once through the Hikvision app. The firmware must re-register the new cell before motion events log correctly to cloud storage — skipping this step can cause recording gaps on the first night.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the DS-MH611 stops recording mid-clip on weak Wi-Fi\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eWhen the DS-MH611 loses Wi-Fi signal and attempts reconnection, the radio draws a short current spike as it renegotiates with the router. On a depleted or degraded cell, that spike pushes the battery below the BMS protection threshold momentarily, triggering a shutdown before the clip saves. The camera logs an incomplete event and goes offline. Fitting a fresh cell at full charge raises the floor voltage enough that the reconnection spike stays within the safe operating window.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eApp showing 0% or stuck percentage after battery swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe DS-MH611 uses a voltage-threshold indicator — not a fuel-gauge IC — to estimate charge level. When a new cell is installed, the camera's firmware compares resting voltage against stored threshold tables, and a mismatch can display 0% or a frozen value. This corrects itself after one complete charge-to-discharge-to-full-charge cycle. Plug the camera in until the indicator shows 100%, then let it discharge through normal use before recharging — the percentage will track accurately from that point.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43377756831834,"sku":"BWCS-HKV611MC-1","price":43.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43377756864602,"sku":"BWCS-HKV611MC-2","price":51.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43377756897370,"sku":"BWCS-HKV611MC-3","price":56.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-HKV611MC-1.webp?v=1778771922","url":"https:\/\/batteryweb.com\/products\/hikvision-ds-mh611-replacement-battery-37v-800mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
