Fujitsu iPAD 100 Barcode Scanner Replacement Battery DT-5023BAT 3.7V

Fujitsu iPAD 100 Series — 3.7V Li-ion Replacement Battery (DT-5023BAT)

This 3.7V, 3600mAh Li-ion battery replaces the original pack in the Fujitsu iPAD 100 barcode scanner series. It fits the iPAD 100, iPAD 100-10, iPAD 100-10RF, and iPAD 100-14, among other variants in the same family. OEM part numbers DT-5023BAT, DT-5024LBAT, and CA50601-1000 all cross to this pack.

• iPAD 100 series fit: All listed iPAD 100 variants share the same 3.7V battery bay, connector pinout, and BMS handshake. Swapping between sub-models in this family does not require a different pack — the BMS reads the same identification data across all of them.
• Bench tested on actual hardware: We cycled this pack through repeated scan-trigger and wireless radio loads. The BMS held the correct charge termination voltage and did not trip on combined inrush from the imager and the radio transmitting simultaneously.
• First-shift preparation: After installing, seat the scanner in its cradle and run a full charge cycle before the first pick-and-pack shift. The scan trigger draws its highest inrush current when the cell is near minimum charge, and a fully charged cell prevents false BMS cutoffs during that first heavy-use period.

Cradle showing charging error on a new pack

The iPAD 100 cradle reads pack state through the dock contacts before initiating a charge cycle. If those contacts have oxidation or debris, the dock can report a fault even with a brand-new cell installed. Wipe the gold contacts on both the battery and the cradle base with a dry cloth, then reseat the scanner firmly. The charge LED should switch from fault to active within a few seconds of clean contact.

Scanner losing wireless connection during rapid scan bursts

During a fast scan sequence, the imager trigger and the wireless radio fire simultaneously, creating a combined inrush current spike that a degraded or partially discharged cell cannot sustain. The BMS responds by briefly pulling back output, and the radio drops its connection. This is not a wireless or firmware issue — it is a power delivery problem. Charge the pack fully before a high-volume shift and confirm the cell voltage reads 4.1–4.2V at the start of the day.
