It replaces OEM part numbers 872766, RRC1130, and 110019-08 directly. The slim 83.60 × 61.00 × 6.60mm cell slots into the same bay as the factory pack.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eBLK3D Imager and BLK3D Imager Premium compatibility:\u003c\/strong\u003e\n    Both devices share the same battery bay geometry, connector pinout, and BMS handshake protocol — one cell covers the full range without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this pack through the BLK3D's startup sequence, sensor initialisation, and sustained imaging load. The BMS held stable voltage across the full discharge curve without triggering a low-power cutoff during active scanning.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install calibration — run it before your first field session:\u003c\/strong\u003e\n    After fitting this pack, run a full calibration cycle through the BLK3D instrument menu before deployment. The imager maps battery state during calibration, and skipping this step causes premature low-battery warnings during your first measurement session — even with a fully charged cell.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBMS lockout after the BLK3D Imager sat unused in a case for months\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eLi-Polymer cells self-discharge slowly during storage. If the BLK3D sat in a carry case for an extended period, the pack voltage can drop below the BMS recovery threshold — typically around 3.0V per cell — causing the protection circuit to open and block normal charging. The charger sees no load and stops. To recover the pack, apply a trickle charge at a low current using a compatible Li-Polymer charger with a recovery or wake mode until cell voltage rises above 3.2V, then switch to standard charge.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBLK3D shuts down mid-scan even though the battery indicator shows charge remaining\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the voltage indicator on the display has not yet recalibrated to the new cell's discharge curve. The imager's fuel gauge was tuned to the old, degraded pack — it reads remaining charge inaccurately until it logs a full discharge cycle. Run the battery from a full charge down to the automatic cutoff point without interrupting the session. After one complete cycle, the indicator recalibrates and low-battery warnings align with actual cell voltage.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43360528990298,"sku":"BWCS-LKD300SL-1","price":41.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43360529023066,"sku":"BWCS-LKD300SL-2","price":47.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43360529055834,"sku":"BWCS-LKD300SL-3","price":52.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-LKD300SL-1.webp?v=1778615946","url":"https:\/\/batteryweb.com\/products\/leica-blk3d-imager-replacement-battery-385v-4000mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
