It replaces part number AHB765965P and restores the camera's original cell capacity. Rated at 17.48Wh, it matches the voltage and physical footprint of the factory cell.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eCS-DP1C and CS-DP1C-4A1WPFBSR compatibility:\u003c\/strong\u003e\n    Both models run the same 3.8V power rail and use the same AHB765965P cell with identical connector and BMS handshake requirements — the same replacement battery fits both variants 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 a CS-DP1C unit and confirmed the BMS accepted the cell, voltage reported correctly through the Ezviz app, and motion recording logged to cloud storage without interruption.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-install power cycle:\u003c\/strong\u003e\n    After fitting the new cell, power cycle the camera once through the Ezviz app. The firmware must register the new battery before motion event logging initialises correctly — skipping this step can cause missed recordings even when the cell reads charged.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the CS-DP1C goes offline in the app after a battery swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eReplacing the battery cuts power long enough for the camera to lose its active session token with the Ezviz cloud. When power returns, the firmware attempts to reconnect using a stale token and the app shows the device as offline. This is not a battery fault — it is a re-authentication step. Open the Ezviz app, navigate to the device settings, and trigger a manual restart to force a fresh token handshake. The camera typically comes back online within 60 seconds of that restart.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eApp reporting 0% or wrong battery percentage after install\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe CS-DP1C uses a voltage-threshold indicator, not a fuel gauge IC, so the percentage display is calculated from resting cell voltage at fixed reference points. A new cell installed at partial charge will read incorrectly until the camera completes one full charge cycle. Charge the battery to 100% via the app indicator, then allow it to discharge naturally through normal operation. After that single cycle the threshold calibration resets and the percentage display tracks correctly.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43377748639834,"sku":"BWCS-EZP110SL-1","price":38.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43377748672602,"sku":"BWCS-EZP110SL-2","price":45.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43377748705370,"sku":"BWCS-EZP110SL-3","price":49.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-EZP110SL-1.webp?v=1778771922","url":"https:\/\/batteryweb.com\/products\/ezviz-cs-dp1c-4a1wpfbsr-replacement-battery-38v-4600mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
