Casio HA-G20BAT DT-X30 Replacement Battery 7.4V 2200mAh

Casio DT-X30 Series — 7.4V Li-ion Replacement Battery (HA-G20BAT)

This 7.4V 2200mAh Li-ion battery replaces the original HA-G20BAT pack in the Casio DT-X30 mobile data terminal. It fits the DT-X30, DT-X30G, DT-X30GR-30C, and IT-9000 handheld scanners used in warehouse, retail, and field data capture environments. Voltage, connector, and BMS handshake match the OEM specification.

• DT-X30 and IT-9000 platform fitment: These models share the same battery bay dimensions, 7.4V rail, and HA-G20BAT connector pinout. The BMS communication protocol is consistent across the DT-X30G and DT-X30GR-30C variants, so one pack covers the entire series without modification.
• Bench tested on actual hardware: We ran this pack through a full charge cycle on the DT-X30 and verified BMS handshake with the host device. The scanner recognised the pack immediately, accepted charge via the cradle, and the scan trigger fired without tripping a low-voltage cutoff event.
• First-shift preparation: After installing this pack, seat the scanner in its cradle and run a complete charge cycle before the first pick-and-pack shift. Scan trigger inrush current is highest when the cell is near minimum state of charge, and starting with a full cell prevents false BMS trips on the first use.

Cradle showing a charging error on a new pack

Casio charging cradles use dock contact resistance to verify a valid pack is seated before initiating a charge cycle. Oxidation or debris on the battery's gold contacts raises that resistance above the cradle's threshold, triggering an error LED even on a brand-new cell. Wipe the battery contacts and cradle pins with a dry lint-free cloth, then reseat the pack firmly until it clicks. That alone clears the error in most cases — no firmware reset required.

Scanner losing wireless connection during rapid scan bursts

During a rapid scan sequence, the DT-X30 draws current simultaneously from the imager, the wireless radio polling the access point, and the processor logging each transaction. That combined inrush can cause a brief voltage sag on a degraded or partially charged cell. When the voltage dips below the radio module's minimum operating threshold, the wireless stack drops the connection before the BMS reaches full cutoff. Starting each shift with a fully charged pack keeps the voltage rail high enough to handle the combined draw without sag-induced dropouts.
