It replaces OEM part numbers 200-00552 and 200-00589. These scanners are used in retail and warehouse pick-and-pack operations where scanner downtime directly stalls throughput.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003e7300 \/ 7400 series platform fit:\u003c\/strong\u003e\n    The 7300, 7400, 7450, and HH-7400M share the same battery bay dimensions, connector pinout, and BMS handshake protocol — one cell 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 the 7400's BMS on the bench. The protection circuit responded correctly to scan-trigger inrush and wireless radio draw, holding voltage without tripping the low-cell cutoff under combined load.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-shift cradle conditioning:\u003c\/strong\u003e\n    After installing a new pack, seat the scanner in its cradle for a full charge cycle before sending it to the floor. Scan-trigger inrush current peaks when the cell is near minimum charge, and a fresh-from-box Ni-MH cell can trip the BMS cutoff on the first heavy scan burst if deployed uncharged.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCradle showing charging error on a new pack\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH cells fresh from storage can sit at a resting voltage that the Dolphin cradle's charge controller reads as a fault condition rather than a discharged pack. The dock checks cell voltage on contact before initiating a charge cycle — if the reading falls outside its expected window, it flags an error instead of charging. Wipe the battery contacts and cradle terminals with a dry cloth and reseat the pack firmly. If the error persists, remove the pack, wait 10 seconds, and reseat — this resets the dock's contact-detection handshake.\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\"\u003eOn the 7400 series, the radio transmitter and the scan trigger fire simultaneously during fast-paced scanning — the combined inrush can pull voltage down momentarily if the cell is partially depleted. The BMS interprets this voltage sag as a low-cell event and briefly cuts power to non-essential subsystems, which drops the wireless link. The fix is to avoid running the pack below roughly 3.3V under load — if the scanner is losing connection mid-shift, return it to the cradle before the shift ends, not after.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43324929933402,"sku":"BWCS-HD7400BL-1","price":38.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 2 Year","offer_id":43324929966170,"sku":"BWCS-HD7400BL-2","price":45.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 3 Year","offer_id":43324929998938,"sku":"BWCS-HD7400BL-3","price":49.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-HD7400BL-1.webp?v=1778123426","url":"https:\/\/batteryweb.com\/products\/dolphin-7300-replacement-battery-36v-2700mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
