It shares the same OEM part numbers 1810-0001, 1810-001, and 1810-7100. Physical dimensions are 70.80 × 38.50 × 21.00mm — confirm fit before ordering if your unit has an aftermarket housing.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eM7100 and M7220 platform fit:\u003c\/strong\u003e\n    These models share a common battery bay, contact layout, and BMS handshake protocol. One pack covers the full M71-series line without adapter or modification.\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 the M7100 platform. The BMS accepted the charge handshake from the OEM cradle without error flags, and voltage held within spec through repeated scan-trigger bursts combined with active wireless polling.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-shift preparation — M71-series cradle:\u003c\/strong\u003e\n    After installing a new pack, seat the scanner in its cradle and let it complete a full charge cycle before starting pick-and-pack work. The scan trigger draws its highest inrush current when the cell is near minimum — a partially charged new cell can trip the BMS on the first shift and cause a false low-battery shutdown.\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\"\u003eAML cradles use contact resistance to verify the pack is seated correctly before starting a charge cycle. Dust, warehouse grime, or oxidation on the gold contacts can push resistance above the dock's threshold, causing it to flag an error rather than charge. This is common with new packs straight out of packaging — the contacts may have light oxidation from storage. Wipe the battery contacts and cradle pins with a dry lint-free cloth, reseat the pack firmly, and the charging indicator should clear within 30 seconds.\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\"\u003eFast barcode scanning and active wireless transmission hit the battery simultaneously — the scan trigger and the radio both draw current at the same moment. On a depleted or degraded cell, this combined inrush causes a momentary voltage sag that drops below the BMS cutoff, briefly killing the radio link. The scanner reconnects once voltage recovers, but the dropped connection resets the transmission queue and causes data gaps. If this happens repeatedly, check cell voltage at rest — anything below 7.0V under no load means the pack needs replacement.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43324872982618,"sku":"BWCS-AML710BL-1","price":32.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43324873015386,"sku":"BWCS-AML710BL-2","price":37.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43324873048154,"sku":"BWCS-AML710BL-3","price":41.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-AML710BL-1.webp?v=1778123298","url":"https:\/\/batteryweb.com\/products\/aml-m7100-replacement-battery-74v-2200mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
