GICOM GC9600 Replacement Battery 3.7V 1800mAh Li-ion

GICOM GC9600 / LK9100 / LK9150 — 3.7V Li-ion Replacement Battery

This 3.7V, 1800mAh (6.66Wh) lithium-ion battery replaces the stock pack in the GICOM GC9600, LK9100, and LK9150 handheld barcode scanners. These are portable imager units used in warehouse, retail, and inventory environments. The cell dimensions are 53.19 × 35.67 × 11.43mm — confirm against your existing pack before ordering.

• GC9600, LK9100, LK9150 compatibility: All three models run the same 3.7V single-cell architecture with a matching footprint and connector pinout. The BMS in each unit uses the same charge termination voltage, so one cell format serves the whole range without modification.
• Bench tested on actual hardware: We cycled this cell through simulated scan burst loads and monitored BMS response at low state-of-charge. The protection circuit held cutoff correctly and did not trip under the combined inrush of the imager and wireless radio during back-to-back scans.
• First-shift preparation: After installing this pack, seat the scanner in its cradle and run a full charge cycle before picking it up for a shift. Scan trigger inrush is highest when the cell is near minimum voltage, and starting from a full charge prevents false BMS trips during the first hour of use.

Cradle showing a charging error on a freshly installed pack

A new cell that has been stored for several months can arrive at a resting voltage below the cradle's charge-initiation threshold. Some docks read this as a fault rather than a deeply discharged cell. If the dock flashes an error immediately after seating the new battery, remove the scanner, wipe the gold contact pads on both the pack and the dock with a dry cloth, then reseat firmly. If the error clears after a minute, the dock has resumed normal charge — the initial fault was contact resistance, not a bad cell.

Scanner losing wireless connection mid-burst during rapid scanning

Fast back-to-back scans combine imager inrush with the wireless radio's polling cycle, creating a compound current draw that briefly sags cell voltage. If the sag crosses the BMS's low-voltage warning threshold, the radio drops to preserve power. This shows up as intermittent disconnects during high-speed pick operations, not during single slow scans. The fix is to ensure the pack is above 3.6V before starting a high-frequency scan run — check the scanner's battery indicator and top up in the cradle if it reads below two bars.
