Nippon GT10B Replacement Battery 2.4V 1500mAh Ni-MH

Nippon GT10B / SB10N / DS26H2-D — 2.4V Ni-MH Replacement Battery

This is a 2.4V 1500mAh Ni-MH replacement battery for the Nippon GT10B, SB10N, and DS26H2-D handheld barcode scanners. These scanners are used in retail and warehouse environments where batteries cycle daily through scan-heavy shifts. Capacity is 1500mAh (3.6Wh) — matching the original specification exactly.

• GT10B, SB10N, and DS26H2-D compatibility: All three models share the same 2.4V power rail, physical form factor, and BMS handshake protocol. The cell dimensions — 49.20 x 28.93 x 14.73mm — match the battery bay on each device without modification.
• Bench tested on actual hardware: We ran the pack through repeated scan-trigger inrush cycles and monitored the BMS cutoff thresholds. The protection circuit held stable at both low-voltage floor and high-current draw without nuisance tripping during rapid scan bursts.
• First-shift preparation for pick-and-pack use: Before the first shift, seat the scanner in its charging cradle and run a full charge cycle. The scan trigger inrush current peaks when the cell is near minimum — a pre-charged pack prevents false BMS trips that can cut the scanner out mid-scan on the first hour of use.

Ni-MH packs shipped in storage mode sit at a reduced voltage — some cradles read this as a fault rather than a depleted cell. The dock contact resistance between the battery terminals and cradle pins is also a factor. Wipe the gold contacts on the battery and cradle with a dry cloth, then reseat the pack firmly. Most cradles will begin a normal charge cycle within 60 seconds of clean contact being made.

Scanner loses wireless connection during rapid scan bursts

When the scan trigger fires rapidly, the imager and wireless radio draw current simultaneously. On a degraded or partially discharged pack, this combined inrush causes a voltage sag that drops below the radio module's minimum operating threshold, cutting the wireless link. The scanner may still appear to scan locally but stops transmitting. Charge the pack fully before use — the wireless dropout threshold on these models is around 2.0V under load.
