Datalogic ELF Barcode Scanner Replacement Battery BT-10 3.7V

Datalogic ELF — 3.7V Li-ion Replacement Battery (BT-10)

This 3.7V, 5200mAh Li-ion battery replaces the OEM pack in the Datalogic ELF handheld mobile computer. It fits the ELF barcode scanner used in warehouse picking, inventory control, and retail floor operations. Also cross-references OEM part numbers 94ACC1376 and 94ACC1377.

• ELF platform compatibility: The ELF uses a single-cell 3.7V architecture with a BMS handshake through the multi-pin pack connector. This battery matches that voltage rail and connector pinout, so the scanner firmware recognises the pack and reports charge state correctly on the status display.
• Bench tested on actual hardware: We cycled this pack through repeated scan-trigger and wireless radio draw events on an ELF unit. The BMS held cutoff thresholds at both high inrush and sustained low-draw polling — no false trips and no dropped charge readings across the test cycle.
• First-shift preparation for the ELF: After installing, seat the scanner in its charging cradle for a full charge cycle before deploying it in pick-and-pack. Scan-trigger inrush current peaks when the cell is near minimum, and a fully charged pack prevents the BMS from tripping on that first heavy draw of the shift.

Cradle showing a charging error on a new BT-10 pack

ELF cradles communicate with the battery through gold-plated dock contacts on the base of the scanner. If those contacts carry oxidation or debris from a worn-out pack, the cradle throws a charging fault even with a new battery seated. The cradle reads contact resistance above its threshold and interrupts the charge cycle rather than risk an uncontrolled charge. Wipe the contacts on both the scanner base and the cradle with a dry cloth, reseat the scanner firmly, and confirm the charge indicator switches to active within 30 seconds.

Scanner losing wireless connection during rapid scan bursts

During a fast scan burst, the ELF pulls current simultaneously from the imager and the wireless radio — both transmitting data at the same time. If the cell voltage sags below the radio module's minimum operating threshold during that combined draw, the wireless stack drops its connection before the BMS actually cuts off the battery. This looks like a connectivity fault but the root cause is voltage sag under combined load. A new, fully charged 5200mAh pack maintains enough headroom to sustain both loads — check that the replacement pack reads at or above 3.9V before the first shift.
