Casio DT-9023 IT3000 Replacement Battery 7.4V 2200mAh

Casio IT3000 / IT2000 Series — 7.4V Li-ion Replacement Battery (DT-9023)

This 7.4V 2200mAh Li-ion battery replaces the OEM pack in the Casio IT3000 and IT2000 series handheld barcode scanners. It fits models including the IT-2000D30E and IT-2000D33E and uses the same OEM part references: DT-9023, DT-9723, DT-9023LI, DT-9723LI, and DT-9723LIC. It slots directly into the same battery bay and connects to the same BMS handshake these scanners expect.

• IT3000 and IT2000 series fit: Both lines share a common battery form factor and voltage rail at 7.4V. The BMS communication protocol is identical across these models, so the pack registers correctly without triggering a compatibility fault on the device controller.
• Bench tested on actual hardware: We ran this pack through repeated scan-trigger cycles on the IT3000 platform and monitored BMS response under combined laser and wireless radio draw. The BMS held voltage within spec and did not cut off during back-to-back scan bursts.
• First-shift charge discipline: After installing this pack, seat the scanner in its cradle and run a full charge cycle before using it on a pick-and-pack shift. Scan trigger inrush current peaks when the cell is near minimum voltage — a pre-charged pack prevents a false BMS trip on the first burst of the shift.

Cradle showing a charging error on a new pack

Casio IT-series cradles read pack state through the dock contacts before initiating the charge cycle. If those contacts are oxidised or have residue from a worn-out old pack, the cradle throws a charge error even when the new cell is fine. Wipe the gold contacts on the battery and the cradle slot with a dry lint-free cloth, then reseat the pack firmly. The error clears once contact resistance drops below the cradle's threshold and the BMS handshake completes.

Scanner losing wireless connection during rapid scan bursts

During fast scanning runs, the IT3000 draws current simultaneously from the laser or imager and the wireless radio module. If the cell voltage sags under that combined load, the radio subsystem drops its connection before the BMS fully trips. This is most common when the battery is below 30% charge. Keep the pack above that threshold during heavy shift work — check the device charge indicator and return to the cradle before the battery indicator hits the first warning bar.
