It fits both the standard SM10 and the LTE variant used in warehouse, logistics, and retail scanning operations. Voltage and capacity match the OEM specification exactly.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eSM10 and SM10LTE compatibility:\u003c\/strong\u003e\n    Both models run the same 3.8V battery rail and use an identical physical connector and BMS handshake. The SM10LTE adds an LTE radio but draws from the same cell — one battery pack covers both variants without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this pack on the SM10 platform and monitored the BMS through scan trigger cycles and wireless polling intervals. The protection circuit held stable across repeated inrush events and did not trip false low-voltage cutoff during high-frequency scan bursts.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst shift preparation on the SM10:\u003c\/strong\u003e\n    After installing a new pack, seat the scanner in its charging cradle and complete a full charge cycle before starting pick-and-pack operations. Scan trigger inrush current peaks when the cell is near minimum state of charge — a fully charged cell prevents false BMS trips on 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 SM10 battery pack\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eSM10 charging cradles check contact resistance at the dock pins before initiating a charge cycle. If the pack contacts or cradle pins carry oxidation or debris from handling, the dock reads an abnormally high resistance and flags a charging fault rather than starting current flow. Wipe the gold contacts on the battery pack and the corresponding cradle pins with a dry lint-free cloth, then firmly reseat the device. The cradle should clear the fault and begin charging within 10 seconds of reseating.\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 SM10LTE combines an active LTE radio with scan trigger inrush on the same cell — when both draw simultaneously during a high-frequency scan burst, instantaneous current demand can cause a brief voltage sag. If the cell is not fully charged, this sag crosses the radio module's minimum operating threshold and drops the wireless link. The BMS does not trip, but the radio resets and reconnects, which operators see as connection drops mid-task. Keeping the pack above 3.6V during shift operations eliminates this; charge before deployment and rotate packs at shift midpoint in high-scan-rate environments.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43324826910810,"sku":"BWCS-MCM100BL-1","price":34.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43324826943578,"sku":"BWCS-MCM100BL-2","price":40.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43324826976346,"sku":"BWCS-MCM100BL-3","price":44.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-MCM100BL-1.webp?v=1778123184","url":"https:\/\/batteryweb.com\/products\/m3-mobile-sm10-replacement-battery-38v-4200mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
