Replacement Battery for Unitech Scanners

This 3900mAh lithium-ion pack replaces the original power source in Unitech PA700, PA700MCA and PA720 barcode scanners. It delivers 44.46Wh of energy and weighs 386g. The battery uses a fully decoded chip to match the device's original communication protocol.

Upgrade from Lower-Capacity Packs

The unit supersedes earlier 3000mAh or 11.10Wh batteries that may have shipped with the same scanner models. The jump is worthwhile when longer shift coverage is needed without swapping cells mid-day. It fits the same 83.60 x 42.80 x 9.40mm compartment and connects to the existing 3.7V rail.

Limits of Single-Cell Lithium-Ion Chemistry

Capacity drops noticeably below freezing and above 60°C, so outdoor winter use or hot warehouse storage will shorten runtime. The pack cannot be fast-charged beyond the scanner's built-in controller limits. It is not a multi-cell pack, so it cannot supply higher voltages for accessories that require them.
