Kastar FNP120 2300mAh Li-ion Battery

The Kastar FNP120 is a 3.7V 8.51Wh lithium-ion replacement cell built for the Brother DS820W and DS920DW portable scanners. It replaces the original LD0665001 and AP-1908 packs so mobile professionals can keep scanning without a mains connection.

Practical limits of Li-ion chemistry

Capacity fades with every charge cycle so run-time will shorten after a year of daily use. The pack delivers 3.7V nominal voltage and 8.51Wh energy; it cannot supply higher voltages required by larger devices. Extreme cold or sustained heat accelerates permanent capacity loss.

Simple drop-in installation

The battery slides into the scanner’s dedicated compartment and locks with the original latch — no tools or soldering needed. Misalignment is the only common error; forcing the pack can damage the connector pins. The built-in protection circuit guards against over-charge, over-discharge, over-voltage, over-current and over-heating.
