It fits the QS6500BT, QS65-3030000R, QS65-4040001-401R, QS65-2030000R, and related QS65 variants. Rated at 2.96Wh, it matches the OEM cell format at 52.30 × 15.80 × 15.80mm.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eQS65 series compatibility:\u003c\/strong\u003e\n    The QS65 scanner variants share a common 3.7V single-cell architecture, identical connector pinout, and the same BMS communication protocol. One replacement pack covers the full range 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 and wireless polling loads. The BMS held stable cutoff thresholds at both low charge and full charge states, with no false trips during high-frequency scan bursts.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-shift charging protocol:\u003c\/strong\u003e\n    After installing the new pack, seat the scanner in its cradle and run a full charge cycle before the first pick-and-pack shift. Scan trigger inrush current peaks when the cell is near minimum voltage — a pre-charged cell prevents a BMS protection trip on the first heavy scan burst.\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\"\u003eThe QS6500BT cradle reads pack state through the charging contacts before it commits to a charge cycle. If contact resistance is high — from oxidation, debris, or a slight seating angle — the dock flags a fault rather than charge. This is not a faulty battery. Wipe the gold contacts on the pack and the cradle dock with a dry cloth, then reseat firmly until you feel the latch click. The charge indicator should switch to active within a few 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\"\u003eThe QS6500BT runs its Bluetooth radio and scan imager simultaneously during fast scanning sequences. Combined inrush from both draws can cause a momentary voltage sag on a partially charged or degraded cell, dropping the radio link before the BMS trips. If this happens mid-shift, the cell is likely below 3.5V under load. Place the scanner in the cradle until the charge LED shows at least 50%, then resume — the radio connection will stabilise above that threshold.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43324857876570,"sku":"BWCS-DQS650BL-1","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43324857909338,"sku":"BWCS-DQS650BL-2","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43324857942106,"sku":"BWCS-DQS650BL-3","price":29.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-DQS650BL_1.webp?v=1778123298","url":"https:\/\/batteryweb.com\/products\/datalogic-qs6500bt-replacement-battery-37v-800mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
