It matches the original voltage rail and physical footprint of the BAT3000, so the scanner's BMS accepts it without configuration changes. Capacity is 3000mAh (11.1Wh) — identical to the factory specification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eH-27, H-27 1D, and H-27 2D fit:\u003c\/strong\u003e\n    All three variants share the same battery bay geometry, connector pinout, and BMS handshake protocol. The 1D laser and 2D imager modules draw different peak currents at trigger, but both operate within the same 3.7V cell architecture — one pack covers the full H-27 family.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through repeated scan-trigger and wireless polling events on the H-27 platform. The BMS held the output voltage steady through burst scanning sequences and did not trip on the combined radio-plus-imager inrush current at low state of charge.\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 starting pick-and-pack. The scan trigger inrush current peaks when the cell is near minimum — a fully charged pack prevents a false BMS cutoff on the first burst of the 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 charging error on a new BAT3000 pack\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eCharging errors on a new pack are almost always a contact resistance problem, not a cell fault. The H-27 cradle uses spring-loaded dock contacts that accumulate dust and skin oils quickly in warehouse environments. High contact resistance causes the charger to read an abnormal voltage drop and flag an error rather than begin the charge cycle. Wipe the gold contacts on the battery and the cradle with a dry lint-free cloth, reseat the scanner firmly, and the error clears in most cases.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eScanner losing wireless connection during rapid scan bursts\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eDuring a fast scan burst, the imager and the wireless radio draw current simultaneously — the combined inrush can pull the cell voltage below the BMS's minimum threshold for a fraction of a second, causing the radio stack to drop its connection. This is more pronounced when the battery is below 20% charge or if the cell has aged significantly. A replacement pack at full charge raises the available current headroom and eliminates the transient sag that triggers the dropout. If dropouts continue after a full charge, check the wireless channel for interference — a congested 2.4GHz environment amplifies the problem.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43324763537498,"sku":"BWCS-OPH272BL-1","price":43.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43324763570266,"sku":"BWCS-OPH272BL-2","price":50.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43324763603034,"sku":"BWCS-OPH272BL-3","price":55.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-OPH272BL-1.webp?v=1778123082","url":"https:\/\/batteryweb.com\/products\/opticon-h-27-replacement-battery-37v-3000mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
