It fits the M50 directly and uses the OEM part number HMD50. Rated at 17.33Wh, it matches the original cell specification for voltage and capacity.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eM50 platform fit:\u003c\/strong\u003e\n    The M50 uses a slim Li-Polymer cell format with a low-voltage 3.85V rail to keep the housing compact. The HMD50 matches that rail, the physical footprint (84.20 × 69.30 × 9.60mm), and the BMS handshake the scanner's firmware expects on power-up.\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 loads. The BMS held the cutoff threshold correctly at low state-of-charge and did not trip during combined radio and imager draw.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-shift prep for pick-and-pack use:\u003c\/strong\u003e\n    After installing a fresh pack, place the M50 in its cradle for a full charge cycle before the shift begins. Scan-trigger inrush current is highest when the cell is near minimum voltage — a pre-charged cell prevents false BMS trips during the first high-frequency scanning run.\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 HMD50 pack\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens most often because of contact resistance between the pack and the cradle's charging pins. A new cell surface can have a thin film from handling, and the cradle interprets the resistance spike as a fault. Remove the pack, wipe the gold contacts on both the battery and the cradle with a dry cloth, then reseat the pack firmly. The charging indicator should clear within 30 seconds of a solid connection.\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\"\u003eWhen the M50 fires the imager and transmits data over Bluetooth or Wi-Fi at the same time, the combined inrush can cause a momentary voltage sag at the cell terminals. If the pack is weak or deeply discharged, that sag crosses the BMS undervoltage threshold and the radio stack resets to protect the cell. The fix is to keep the pack above 20% state-of-charge during high-frequency scanning. If drops persist on a fully charged new pack, check that the wireless channel is not congested — radio retries increase draw and worsen sag.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43324658516058,"sku":"BWCS-MDH500BL-1","price":64.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43324658548826,"sku":"BWCS-MDH500BL-2","price":76.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43324658581594,"sku":"BWCS-MDH500BL-3","price":85.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-MDH500BL-1.webp?v=1778121683","url":"https:\/\/batteryweb.com\/products\/mindeo-m50-replacement-battery-385v-4500mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
