It replaces OEM part SM15-BATT-S41 and fits the battery bay directly. Capacity figure is taken from verified product data — 23.94Wh.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eSM15, SM15N, SM15W, SM15X compatibility:\u003c\/strong\u003e\n    All four models share the same battery bay geometry, contact pin layout, and BMS communication protocol. The 3.8V nominal rail and the SM15-BATT-S41 part number apply across the entire platform — no adapter or modification needed.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this pack through charge and discharge cycles on SM15 hardware. The BMS handshake completed correctly, the device reported battery status accurately in the status bar, and the protection circuit responded as expected to both charge completion and low-voltage cutoff.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-shift preparation for pick-and-pack:\u003c\/strong\u003e\n    Place the scanner in its cradle for a full charge cycle before the first shift. Scan trigger inrush is highest when the cell sits near minimum voltage — a fully charged pack on day one prevents false BMS trips during the opening burst of a busy 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 freshly installed pack\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA new pack sitting in storage accumulates surface oxidation on its contact pads. When dock contact resistance climbs above a few ohms, the cradle's charge controller reads an abnormal voltage drop across the contacts and flags a fault. Wipe the gold contacts on both the battery and the dock with a dry lint-free cloth, then reseat the unit firmly. If the error clears, the pack was never faulty — the contact path was.\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 SM15 pulls current simultaneously from the scan engine and the Wi-Fi or Bluetooth radio during a fast scan sequence. Combined inrush from both loads can cause a momentary voltage sag that the BMS interprets as a low-cell event, briefly cutting power to the radio subsystem. This shows up as a dropped connection or a \"searching for network\" flag mid-shift. Keeping the pack above 20% charge eliminates most sag events — below that threshold, cell internal resistance rises enough to make simultaneous radio and imager draw problematic.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43324678275162,"sku":"BWCS-MSM150BL-1","price":61.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43324678307930,"sku":"BWCS-MSM150BL-2","price":71.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43324678340698,"sku":"BWCS-MSM150BL-3","price":80.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-MSM150BL-1.webp?v=1778121683","url":"https:\/\/batteryweb.com\/products\/m3-mobile-sm15-replacement-battery-38v-6300mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
