Three-Pack Replacement Battery for Brother Scanners

This Kastar FNP120 pack supplies three lithium-ion cells rated at 3.7 V and 2300 mAh each. They replace the Brother LD0665001, MDS2E and AP-1908 batteries used in the DS820W and DS920DW document scanners.

Thermals Noise and Power Draw

Lithium-ion chemistry runs cool during typical scanning jobs and the built-in protection circuit guards against over-heating. No fan or active cooling is involved so operation stays silent. Each cell stores 8.51 Wh of energy for extended mobile use.

Protection Circuit and Multi-Pack Value

Integrated safeguards prevent over-charge, over-discharge, over-voltage, over-current and over-heating to protect both the battery and the scanner. The three-unit pack lets you keep a spare charged while another is in use, reducing downtime for high-volume scanning. Not suited for devices that require a different voltage or form factor.

Questions about this item

How do I install the Kastar FNP120 battery in my Brother DS820W scanner, and what step do people often miss?

Slide the battery into the compartment until the latch clicks securely; the step many miss is ensuring the gold contacts face the scanner's terminals before closing the cover.

What maintenance or replacement will the Kastar FNP120 3-pack need after extended use?

Each 2300mAh Li-ion cell gradually loses capacity over hundreds of charge cycles; replace a pack when runtime drops below your scanning workload needs.

What limit appears first during sustained scanning with the Kastar FNP120 batteries?

The 8.51 Wh capacity per battery sets the runtime ceiling; continuous high-speed scanning on the DS920DW will deplete a pack before thermal limits activate.
