Compatible Scanner Models

This four-pack of Kastar FNP120 lithium-ion batteries replaces the Brother LD0665001 and AP-1908 cells used in the DS820W and DS920DW document scanners. Each unit delivers 3.7 V and 2300 mAh for direct drop-in operation.

Capacity and Headroom

At 8.51 Wh per cell the pack supplies enough energy for extended scanning sessions without frequent swaps. Runtime scales with scan density and duplex use; very high-volume days will still require a recharge or a spare set.

Included Protection Circuit

Built-in safeguards stop over-charge, over-discharge, over-voltage, over-current and over-heating events before they damage the scanner or the cells. The circuitry also helps preserve cycle life across repeated charges.

Questions about this item

Will the 3.7 V FNP120 cells work in my older Brother DS820W scanner without any adapter?

Yes, the 3.7 V 2300 mAh cells are direct replacements for the Brother LD0665001 pack used in the DS820W, so they fit and power the scanner without an adapter.

How can I confirm each 8.51 Wh pack is charging and holding capacity correctly after first use?

Insert a pack into the DS820W or DS920DW; the scanner’s battery gauge should show a full charge and deliver noticeably longer run-time per cycle thanks to the 2300 mAh rating.

What exactly ships in the 4-pack box and do I need to buy a separate charger?

The box contains four Kastar FNP120 Li-ion cells (part BA-4B-FNP120-S); they are charged inside the Brother DS820W or DS920DW scanner, so no external charger is required.
