It carries 3400mAh (12.58Wh) of capacity — matching the original pack's output for retail, warehouse, and logistics scan environments. Fits scanners using OEM part numbers BAT-492 and 3008-4418-001.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eHH492 platform fit:\u003c\/strong\u003e\n    The HH492 uses a fixed 3.7V single-cell Li-ion pack with a specific connector and BMS handshake. This replacement matches that cell configuration exactly, so the scanner's power management circuit recognises the pack and reports charge state correctly through the host software.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through combined scan-trigger and wireless radio draw events. The BMS held the output rail steady under rapid burst scanning and recovered cleanly from simulated low-voltage cutoff without requiring a manual reset.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-shift charging protocol:\u003c\/strong\u003e\n    After installing, place the scanner in its cradle for a full charge cycle before using in pick-and-pack. Scan trigger inrush current is highest when the cell is near minimum — a fully charged cell prevents false BMS trips during the first shift's burst scanning.\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 pack\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA charging error on a freshly installed battery usually comes down to contact resistance at the dock, not a faulty cell. Dock contacts accumulate oxidation and debris, and a new pack with slightly firmer spring tension can seat at a micro-angle that breaks the circuit. Wipe the gold contacts on both the battery and the cradle with a dry lint-free cloth, then reseat the scanner with firm downward pressure until you hear it click. If the error clears within 10 seconds, the pack is charging normally — if not, check that the cradle rails aren't bent past 1mm of deflection.\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\"\u003eThe HH492 draws simultaneous current from both the scan trigger and the wireless radio during high-frequency burst scanning. On a degraded original battery, this combined inrush pulls the cell voltage low enough to trigger the BMS cutoff, which drops the radio link before the scanner fully powers down. This replacement pack's higher internal cell quality keeps the voltage rail above the BMS floor under that combined load. If drop-outs persist after a full charge, check that the wireless polling interval on the host isn't set below 100ms — tighter polling amplifies the combined inrush event.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43324674900058,"sku":"BWCS-HYH492BX-1","price":55.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43324674932826,"sku":"BWCS-HYH492BX-2","price":64.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43324674965594,"sku":"BWCS-HYH492BX-3","price":71.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-HYH492BX-1.webp?v=1778121683","url":"https:\/\/batteryweb.com\/products\/honeywell-hh492-replacement-battery-37v-3400mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
