The BK10 is used in retail, warehouse, and logistics environments where scanners run through full shifts without returning to a desk. Swapping this pack restores full operating capacity when the original cell has degraded.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eBK10 platform fit:\u003c\/strong\u003e\n    The BK10 uses a single-cell Li-Polymer architecture at 3.7V nominal with a proprietary form factor measuring 73.20 × 59.50 × 15.50mm. This replacement matches that footprint and voltage rail so the onboard BMS reads the pack correctly without throwing a fault code on insertion.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through simulated scan-burst loads — repeated trigger pulls combined with active wireless polling — and confirmed the BMS held voltage without tripping on the combined inrush. Capacity measured consistently at rated output across multiple discharge cycles.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-shift preparation:\u003c\/strong\u003e\n    After installing, seat the scanner in its cradle and run a full charge cycle before the first pick-and-pack shift. Scan trigger inrush current peaks when the cell is near minimum, and a fully charged pack prevents false BMS cutoff events during the highest-demand part of the first shift.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCradle showing a charging error on a new BK10 pack\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eCharging errors on a new pack are almost always a contact resistance issue, not a fault with the cell itself. The BK10 cradle reads pack state through the charge contacts, and even a small film of contamination raises resistance enough to trigger an error flag. Wipe the gold contacts on both the battery and the cradle with a dry cloth, then reseat the pack firmly until it clicks. If the error clears within 30 seconds of reseating, contact resistance was the cause — not the cell.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eScanner drops wireless connection during rapid barcode scan bursts\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe BK10 pulls current from two sources simultaneously during a rapid scan burst — the imager or laser module and the wireless radio maintaining its network link. When the cell voltage sags under that combined load, the radio subsystem can lose enough power to drop its connection before the BMS trips the battery entirely. This is more pronounced in a partially depleted pack. Keep the battery above 20% charge during high-throughput scanning sessions and confirm the cell reads at least 3.5V under load before starting a long picking run.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43324686303322,"sku":"BWCS-MBK100BL-1","price":55.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43324686336090,"sku":"BWCS-MBK100BL-2","price":64.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43324686368858,"sku":"BWCS-MBK100BL-3","price":71.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-MBK100BL-1.webp?v=1778122618","url":"https:\/\/batteryweb.com\/products\/m3-mobile-bk10-replacement-battery-37v-3600mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
