It also fits the KB04, HD609, and additional compact recorder models sharing the same battery bay and connector. Dimensions are 53.10 x 38.40 x 8.00mm — measure your original cell before ordering if you are unsure of your exact model.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eMini DVR3, KB04, HD609 shared battery platform:\u003c\/strong\u003e\n    These models use the same physical cell format, connector pin-out, and voltage rail. The LSQ-88 part number covers all of them because the BMS in each recorder reads the same voltage curve from a single cell chemistry spec.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through charge and discharge on the bench, confirming the BMS accepted the cell without fault flags and that charge termination triggered correctly at full capacity.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-use charge cycle on the Mini DVR3:\u003c\/strong\u003e\n    Insert the new cell and run a full charge inside the recorder before your first recording session. Compact DVR recorders like the Mini DVR3 calibrate the battery-remaining indicator against the first charge cycle — skipping this step can cause the indicator to read inaccurately from the start.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the Mini DVR3 shows a dead-battery icon on a freshly installed replacement cell\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eA new cell shipped in storage state typically sits at 3.5V or below. The Mini DVR3's low-voltage detection threshold can flag anything under roughly 3.6V as a depleted cell before the BMS has a chance to characterise it. The recorder is not rejecting the battery — it is reading a legitimate low resting voltage. Plug the recorder into its charge source immediately after inserting the new cell. Once the cell climbs above 3.6V, the dead-battery icon clears and the device operates normally.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBattery percentage jumping erratically after installing a new LSQ-88 cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Mini DVR3 maps its battery indicator to a voltage-threshold table calibrated against the original cell's discharge curve. A new cell discharges along a slightly different curve until it has completed one or two full cycles, so the percentage reading can jump or skip levels. This is a calibration lag, not a fault with the cell. Run two full charge-to-discharge cycles through the recorder and the indicator will track accurately. After the second cycle, resting voltage at full charge should read 4.1–4.2V.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43333783748698,"sku":"BWCS-SPR300SL-1","price":22.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43333783781466,"sku":"BWCS-SPR300SL-2","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43333783814234,"sku":"BWCS-SPR300SL-3","price":27.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-SPR300SL-1.webp?v=1778213084","url":"https:\/\/batteryweb.com\/products\/koonlung-mini-dvr3-replacement-battery-37v-1100mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
