These scanners are used in retail, warehouse, and logistics environments for continuous barcode scanning and inventory data processing. Sourced to match the original cell dimensions of 91.20 × 61.10 × 11.70mm for correct fit inside the battery bay.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eHMD40 and M40 compatibility:\u003c\/strong\u003e\n    Both models share the same battery bay geometry, connector pinout, and BMS communication protocol — one pack covers either device without modification.\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 radio load sequences. The BMS handled combined inrush correctly and held stable voltage across the discharge curve without tripping under burst scan conditions.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-shift preparation:\u003c\/strong\u003e\n    After installing, place the scanner in its cradle for a full charge cycle before starting work. Scan trigger inrush is highest when the cell is near minimum charge, and a fully pre-charged pack prevents false BMS trips at the start 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 charging error on a freshly installed pack\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA new Li-Polymer pack shipped at storage charge — typically around 3.6–3.7V per cell — can cause some cradles to flag a charge fault if dock contact resistance is too high on first seat. Oxidation or debris on the battery terminals increases that resistance and confuses the dock's charge controller. Wipe the gold contacts on both the battery and the cradle with a dry cloth, then firmly reseat the scanner. If the error clears, the contact surface was the cause — not the cell.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eScanner drops wireless connection during rapid scan bursts\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eDuring high-frequency scan bursts, the imager and wireless radio draw simultaneously, creating a combined inrush spike that can sag cell voltage below the radio module's minimum operating threshold. An aged or partially discharged battery has higher internal resistance and sags faster under that combined load. This battery's 5100mAh capacity gives the cell more headroom to sustain voltage during burst activity. If dropouts continue after a full charge, check that cell voltage reads at or above 3.75V before starting a scan-heavy shift.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43324659073114,"sku":"BWCS-MDH400BL-1","price":64.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43324659105882,"sku":"BWCS-MDH400BL-2","price":76.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43324659138650,"sku":"BWCS-MDH400BL-3","price":85.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-MDH400BL-1.webp?v=1778121683","url":"https:\/\/batteryweb.com\/products\/mindeo-hmd40-replacement-battery-385v-5100mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
