Kastar FNP120 Kit — Battery & Dual Charger

This kit supplies one 2300 mAh lithium-ion battery rated at 8.51 Wh and a compact USB charger that can power two cells simultaneously. It replaces the Brother LD0665001 and AP-1908 packs used in DS820W and DS920DW wireless document scanners. The charger accepts Micro-USB or Type-C input at 5 V 2–3 A and delivers 4.2 V 800 mA per slot.

Suits DS820W and DS920DW operators

Scanner owners needing a spare or replacement cell with an LCD dual-slot charger will find the voltage and capacity matched to the original packs. Buyers who want more storage than 8.51 Wh or who require a charger for a different battery chemistry should look at other options.

8.51 Wh capacity decides fit

The 3.7 V 2300 mAh cell provides exactly 8.51 Wh, the energy value the scanner firmware expects for accurate runtime reporting. If your device specifies a different watt-hour rating this kit will not report capacity correctly.
