It fits the SF51 series used in warehouse picking, asset tracking, and point-of-sale environments. OEM part numbers covered include 318-025-001, 317-018-002, 317-018002A, 1016AB01, and 318-024-002.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eSF51 platform fit:\u003c\/strong\u003e\n    The SF51 runs a single-cell 3.7V Li-ion architecture with a BMS that monitors cell voltage and communicates state-of-charge to the host device. Replacement cells must match the voltage rail and BMS handshake protocol — this pack does both.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this battery through scan-burst sequences and monitored BMS cutoff thresholds. The protection circuit responded correctly to over-discharge and over-current events, and the charge IC accepted the pack without fault codes.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-shift preparation for the SF51:\u003c\/strong\u003e\n    After installing, seat the scanner in its charging cradle and run a full charge cycle before putting it on the floor. The scan trigger draws the highest inrush current when the cell is near minimum voltage — a pre-charged pack prevents false BMS trips on the opening scans of a 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 pack\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe SF51 cradle reads contact resistance before initiating a charge cycle. If dock contacts on the scanner base or cradle are oxidised or dirty, the charger sees an open circuit and throws a fault rather than charging. Wipe the gold contacts on both the battery end and the cradle dock with a dry lint-free cloth, then reseat the scanner firmly. If the error clears, the issue was contact resistance — not the battery or charger.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eScanner dropping wireless connection during rapid scan bursts\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe SF51 pulls simultaneous current for both the scan engine and the wireless radio during a rapid burst sequence. At low state-of-charge, combined draw can cause a brief voltage sag that trips the BMS or starves the radio, dropping the connection mid-session. This is not a radio fault — it is a battery voltage floor issue. Keep the pack above 3.5V during active shifts by swapping at the first low-battery alert rather than working to cutoff.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43324890316890,"sku":"BWCS-ISF510BL-1","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43324890349658,"sku":"BWCS-ISF510BL-2","price":30.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43324890382426,"sku":"BWCS-ISF510BL-3","price":33.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-ISF510BL_1.webp?v=1778123334","url":"https:\/\/batteryweb.com\/products\/intermec-sf51-replacement-battery-37v-2200mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
