It also fits the Dolphin 7400 and 7450 mobile data collection terminals. All three share the same internal bay dimensions and connector — one part number covers the range.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eDolphin 7300, 7400, and 7450 compatibility:\u003c\/strong\u003e\n    These three terminals run the same 2.4V internal battery rail and use an identical physical bay. The BMS handshake is consistent across the series, so a single cell fits all three without modification or adapter.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through charge and discharge cycles on Dolphin 7300 hardware. The BMS accepted the pack without fault codes, and the scanner proceeded through normal boot without triggering a low-battery warning at the first scan burst.\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 using it on a shift. The scan trigger inrush current is highest when the cell is near minimum voltage — a fully charged cell prevents false BMS trips during the first heavy scan sequence of the day.\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\"\u003eDolphin cradles use contact pins that oxidise with regular use. When contact resistance increases, the cradle misreads the new cell's charge state and flags an error rather than starting a charge cycle. This is not a fault with the battery — it is a dock contact issue. Wipe the battery terminals and cradle pins with a dry cloth, reseat the scanner 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 a rapid scan burst\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eDuring a fast scan sequence, the Dolphin 7300 draws simultaneously from the imager and the wireless radio. On a degraded or partially charged cell, this combined inrush pulls the cell voltage below the radio's minimum operating threshold momentarily. The radio drops and the scanner appears to freeze or lose its connection to the host system. Charging the replacement cell fully before deployment — confirmed at 2.4V open circuit — eliminates this behaviour.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43324955852890,"sku":"BWCS-HD7300BL-1","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43324955885658,"sku":"BWCS-HD7300BL-2","price":28.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43324955918426,"sku":"BWCS-HD7300BL-3","price":30.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-HD7300BL-1.webp?v=1778123427","url":"https:\/\/batteryweb.com\/products\/handheld-dolphin-7300-replacement-battery-24v-300mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
