iMozen TC601 Replacement Battery 3.85V 3900mAh 1ICP7/54/64

iMozen TC601 / TC601A — 3.85V Li-ion Replacement Battery (1ICP7/54/64)

This is a 3.85V, 3900mAh Li-ion replacement battery for the iMozen TC601 and TC601A handheld barcode scanners. It matches the OEM part number 1ICP7/54/64 and fits directly into the battery compartment on both models. Voltage and capacity figures come from the product data — not estimated from web sources.

• TC601 and TC601A compatibility: Both models run the same 3.85V power rail and use the same battery compartment dimensions (76.00 × 59.00 × 8.50mm). The BMS handshake and connector pinout are identical across the two variants, so one part number covers both.
• Bench tested on actual hardware: We cycled this pack through repeated scan-trigger events and wireless polling loads. The BMS held voltage within spec under combined inrush from the imager and radio, with no false cutoff trips at low state of charge.
• First-shift preparation: After installing, seat the scanner in its cradle and run a full charge cycle before the first pick-and-pack shift. Scan-trigger inrush current peaks when the cell is near minimum — a fully charged pack prevents the BMS from tripping on the first heavy burst of the day.

Cradle showing a charging error on a new pack

Charging errors on a freshly installed pack are almost always a contact resistance issue, not a fault with the battery itself. The TC601 cradle reads pack state through the same gold contacts that carry charge current — if those contacts are dirty or misaligned, the dock flags an error before charging starts. Wipe the contacts on both the battery and the cradle with a dry cloth, then reseat the scanner firmly until it clicks. If the error clears, the pack will charge normally from that point.

Scanner stops reading barcodes mid-shift after battery swap

If the scanner powers on but the imager stops firing during use, the cell voltage has likely dropped below the minimum threshold the imager module needs to trigger. This happens when a replacement pack is installed and used immediately without a full charge — the imager draws a sharp inrush spike that the BMS treats as an undervoltage event and cuts. Place the scanner in the cradle, charge to 100%, and confirm the battery indicator shows a full state before returning the unit to active scanning duty. The imager requires at least 3.6V sustained at the rail to fire consistently.
