Denso GT10B Barcode Scanner Replacement Battery 2.4V 1500mAh

Denso GT10B / DS26H2-D — 2.4V Ni-MH Replacement Battery (SB10N)

This is a 2.4V, 1500mAh Ni-MH replacement battery for the Denso GT10B and DS26H2-D handheld barcode scanners. Both models use the SB10N pack with the same connector orientation and BMS handshake. Capacity is sourced from product specification — 3.6Wh total energy.

• GT10B and DS26H2-D shared platform: These two Denso scanners run the same 2.4V power rail, use an identical battery bay, and expect the same BMS communication protocol. One replacement pack covers both units — no modification needed.
• Bench tested on actual hardware: We ran the SB10N through charge and discharge cycles on compatible Denso hardware. The BMS completed full charge acceptance without tripping fault flags, and the pack held rated voltage through scan-burst load events.
• First-shift preparation for pick-and-pack: Before the first shift, seat the scanner in its cradle and run a complete charge cycle. The scan trigger draws a sharp inrush current when the cell is near minimum — a fully charged pack prevents false BMS trips that cut the unit out mid-scan during initial use.

Cradle showing a charging error on a new SB10N pack

A new Ni-MH pack can sit at a low resting voltage after shipping, and some Denso cradles interpret this as a fault rather than a discharged cell. The dock checks cell voltage on contact before initiating the charge cycle — if it reads below its acceptance threshold, it throws an error instead of charging. Wipe the battery contacts and cradle terminals with a dry cloth, reseat the pack firmly, and remove any debris from the bay. If the error clears, let the cradle complete a full charge to 2.4V before pulling the scanner for use.

Scanner drops wireless connection during rapid scan bursts

During fast barcode scanning, the radio and the scan trigger fire simultaneously, creating a combined inrush spike that can pull cell voltage below the radio module's minimum operating threshold for a fraction of a second. When that happens, the wireless stack drops its connection and must re-associate — users see the scanner pause or lose its session mid-task. This is more pronounced when the cell is below 50% charge. Keep the pack above half charge during high-frequency scanning shifts, and avoid running the unit until the low-battery indicator triggers on a high-volume pick line.
