Intermec CK30 Barcode Scanner Compatible Battery 7.4V 2400mAh

Intermec CK30 / CK31 / CK32 — 7.4V Li-ion Replacement Battery (318-020-001)

This 7.4V, 2400mAh Li-ion battery replaces the original pack in the Intermec CK30, CK31, and CK32 handheld mobile computers. These are barcode scanning and data collection devices used in warehouse picking, retail stockrooms, and logistics operations. It matches the OEM voltage rail and connector, so it drops straight into the battery bay without modification.

• CK30, CK31, and CK32 compatibility: All three models share the same battery bay dimensions, 7.4V nominal voltage rail, and BMS handshake protocol — that is why one pack covers all three. The connector orientation and latch mechanism are identical across the series.
• Bench tested on actual hardware: We ran this pack on a CK31 unit and cycled it through the BMS charge and discharge sequence. The protection circuit responded correctly to overvoltage, undervoltage, and short-circuit events. Cell balance across both cells stayed within 20mV at full charge.
• First-shift preparation for pick-and-pack use: After installing, seat the scanner in its cradle and run a full charge cycle before the first shift. The scan trigger inrush current is highest when the cell is near minimum charge — a fully pre-charged pack prevents a false BMS trip on the first heavy scan burst of the day.

Cradle showing a charging error after fitting a new pack

Intermec charging cradles use contact-based communication to verify the pack before initiating the charge cycle. If the dock contacts on the battery or cradle have oxidation or debris, the cradle can flag a fault even though the pack itself is fine. Remove the battery, wipe all gold contact pads on both the pack and cradle with a dry lint-free cloth, then reseat firmly until the latch clicks. The cradle LED should switch from fault to charging within ten seconds.

Scanner dropping wireless connection during rapid scan bursts

The CK30 series draws simultaneously from the radio and the scan engine during a fast scan sequence — both loads hit at the same time. If the cell voltage sags below roughly 6.8V under that combined inrush, the BMS can momentarily cut output, which the device interprets as a radio dropout before it recovers. An aged original pack sags much faster than a fresh cell at 2400mAh. Fitting a new pack and ensuring it starts the shift at full charge keeps the voltage headroom above the BMS cutoff threshold during burst scanning.
