These are compact wireless scanners used in retail and inventory environments. The cell measures 43.47 × 19.64 × 9.30mm and drops directly into the original battery bay.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eCHS 7 Series compatibility:\u003c\/strong\u003e\n    The 7Qi, 7X, 7Xi, and 7XRx share the same battery form factor, connector pinout, and BMS handshake protocol — one cell fits the full row because the voltage rail and physical housing are identical across those variants.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this pack in a CHS 7Qi unit and monitored the BMS through scan trigger events and Bluetooth polling cycles. The protection circuit held within spec under combined radio and imager inrush without tripping prematurely.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-shift preparation:\u003c\/strong\u003e\n    After installing, seat the scanner in its charging cradle and run a full charge cycle before taking it onto the floor. Scan trigger inrush is highest when the cell is near minimum, and a fully charged pack prevents false BMS cutoff events 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\"\u003eWhy the CHS 7Qi drops Bluetooth during rapid scan bursts\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe CHS 7Qi fires its imager and maintains a Bluetooth polling connection simultaneously. During a rapid scan burst, both draw current at the same moment. On a degraded or low cell, the combined inrush pulls the voltage below the BMS threshold, which drops the radio stack to protect the cell. The connection resumes once voltage recovers, but the host system logs it as a disconnect. A fresh, fully charged cell keeps the voltage rail stable enough to handle both loads without the BMS intervening.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCradle showing a charging error immediately after fitting a new pack\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis usually points to contact resistance between the battery terminals and the dock's charge pins, not a fault with the cell itself. Oxidation or debris on either the pack contacts or the cradle pins raises resistance enough that the charger reads an abnormal load and flags an error. Wipe the battery contacts and cradle pins with a dry cloth, reseat the scanner firmly, and check that the charge indicator activates within 30 seconds. If the error persists after reseating, check cradle pin spring tension — pins should sit proud of the housing and apply firm pressure at 3.7V nominal.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43324768256090,"sku":"BWCS-SKH700BL-1","price":29.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43324768288858,"sku":"BWCS-SKH700BL-2","price":33.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43324768321626,"sku":"BWCS-SKH700BL-3","price":37.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-SKH700BL-1.webp?v=1778123082","url":"https:\/\/batteryweb.com\/products\/socket-mobile-chs-7qi-replacement-battery-37v-600mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
