It fits the DT-X7, DT-X7M10E, and DT-X7M10R mobile data terminals used in warehouse, retail, and inventory environments. Capacity matches the original specification from the product data.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eDT-X7 platform fit:\u003c\/strong\u003e\n    The DT-X7, DT-X7M10E, and DT-X7M10R share the same battery bay dimensions, 3.7V rail, and BMS handshake protocol — one pack covers all three variants 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 inrush events and wireless polling loads. The BMS held the cutoff threshold correctly and did not trip under combined radio and imager draw.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-shift preparation:\u003c\/strong\u003e\n    After installing, seat the scanner in its cradle and run a full charge cycle before taking it to the floor. Scan trigger inrush current peaks when the cell is near minimum charge — a pre-charged pack prevents false BMS trips during the first pick-and-pack 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 HA-F21LBAT pack\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe DT-X7 cradle communicates with the battery over a dedicated contact strip on the base of the pack. If any of those contacts have residue, oil, or oxidation from handling, the dock reads elevated contact resistance and flags a charging fault — not a dead battery. Wipe the gold contacts on both the pack and the cradle dock with a dry lint-free cloth before reseating. If the error clears after reseating, the cell itself is fine and the charge cycle will proceed normally.\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 DT-X7 draws current simultaneously from the imager and the wireless radio during a rapid scan burst — both fire at near the same instant when the trigger is held in high-frequency mode. If the cell voltage sags below the BMS low-voltage threshold at that combined load, the scanner drops the wireless link before it drops the imager, because radio power is the first rail the firmware sheds. This is not a wireless fault — it is a voltage sag event. Charge the pack to full before the shift and confirm cell voltage reads at least 3.7V before logging in to the network.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43324979413082,"sku":"BWCS-DTX7BL-1","price":29.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43324979445850,"sku":"BWCS-DTX7BL-2","price":33.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43324979478618,"sku":"BWCS-DTX7BL-3","price":36.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-DTX7BL_1.webp?v=1778123427","url":"https:\/\/batteryweb.com\/products\/casio-dt-x7-replacement-battery-37v-1880mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
