It replaces OEM part number T18. The cell fits the original battery compartment and connects to the same BMS interface the camera firmware expects.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eDS-MDT101\/GLE fit:\u003c\/strong\u003e\n    The DS-MDT101\/GLE uses a 3.8V single-cell architecture. The T18 footprint, connector pinout, and BMS handshake are specific to this model — other Hikvision camera batteries at different voltages or form factors will not seat or register correctly.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through motion-trigger events and night-vision sequences on the DS-MDT101\/GLE. The BMS negotiated charge cutoff at the correct 4.35V ceiling and held protection thresholds during the combined IR LED and processor draw spikes.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-install firmware registration:\u003c\/strong\u003e\n    After fitting the new cell, power cycle the camera once through the Hik-Connect or IVMS-4500 app. The firmware must register the new cell before motion events log correctly to cloud storage — skipping this step can cause missed recordings even when the battery reads charged.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCamera going offline in the app after battery swap on DS-MDT101\/GLE\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eSwapping the battery on the DS-MDT101\/GLE clears the device's active session token. The camera attempts to re-establish its WiFi connection on boot, but if the firmware hasn't completed its initialisation cycle, the app registers it as offline rather than reconnecting. This is not a pairing fault — no re-adding to the account is needed. Open Hik-Connect, navigate to the device, and trigger a manual refresh. If it remains offline, hold the reset button for three seconds to force a clean reconnect without wiping configuration.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eApp displaying 0% or frozen percentage after installing replacement cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe DS-MDT101\/GLE uses a voltage-threshold indicator, not a fuel-gauge IC. When a new cell at a different resting voltage than the depleted original is installed, the firmware's stored threshold map is misaligned and reports 0% or a stale figure. One full charge-to-discharge cycle resets the threshold map to the new cell's actual voltage curve. Charge the camera to full via USB-C, let it run through at least one night-vision session, then recharge — the percentage display will track accurately from that point.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43377756635226,"sku":"BWCS-HVT101SL-1","price":57.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43377756667994,"sku":"BWCS-HVT101SL-2","price":67.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43377756700762,"sku":"BWCS-HVT101SL-3","price":75.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-HVT101SL-1.webp?v=1778771922","url":"https:\/\/batteryweb.com\/products\/hikvision-ds-mdt101gle-replacement-battery-38v-4850mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
