Intermec CV30 Barcode Scanner Compatible Battery AB5 3.7V 3400mAh

Intermec CV30 — 3.7V Li-ion Replacement Battery (AB5)

This is a 3.7V Li-ion 3400mAh replacement battery for the Intermec CV30 mobile computer. It fits the CV30 series handheld barcode scanner used in warehouse, inventory, and retail environments. The OEM part number is AB5.

• CV30 platform fit: The CV30 runs a single-cell Li-ion pack at 3.7V with a specific BMS handshake through the battery contacts. This replacement matches that voltage rail and connector footprint so the device firmware recognises the pack without throwing a battery fault.
• Bench tested on actual hardware: We ran this pack through full charge and discharge cycles on a CV30 unit, verifying BMS communication, contact continuity, and cutoff behaviour at low-voltage threshold. The protection circuit responded correctly at both ends of the charge curve.
• First-shift preparation for pick-and-pack use: After installing, place the scanner in its cradle for a complete charge cycle before putting it into rotation. The scan trigger draws peak inrush current — highest when the cell is near minimum — and a fully charged pack prevents false BMS trips during the first shift.

Cradle showing charging error on a new AB5 pack

A charging error on a new pack is almost always a contact resistance issue, not a faulty battery. The CV30 cradle reads the pack through spring-loaded dock contacts that accumulate oxidation and debris over time. Wipe the gold contacts on both the battery and the cradle with a dry lint-free cloth, then reseat the scanner firmly. If the error clears, the pack was never the problem.

Scanner losing wireless connection during rapid scan bursts

The CV30 draws current simultaneously from its radio module and scan trigger during a rapid burst sequence. When a degraded or partially charged battery can't sustain voltage under that combined load, the radio drops before the scan engine does — the result looks like a connectivity fault, not a power fault. The fix is to ensure the replacement pack is fully charged before the shift starts. A cell at 3.7V nominal under load should hold above 3.4V during burst; anything lower will trigger the radio cutoff first.
