Compatible Battery Pack for Brother Scanners

This three-battery set replaces the Brother LD0665001 and AP-1908 cells used in the DS820W and DS920DW wireless document scanners. Each cell is a 3.7 V lithium-ion unit rated at 2300 mAh and 8.51 Wh. The bundle includes the LTD2 dual-slot charger so users can keep spare packs ready for mobile scanning workflows.

Dual-Slot USB Charger

The LTD2 charger accepts 5 V at 2–3 A (15 W) through either Micro-USB or Type-C ports and can charge two batteries simultaneously at 4.2 V and 800 mA per slot. An intelligent LCD shows real-time charging status and remaining capacity for each cell. A Micro-USB cable is supplied in the box.

Low-Heat Charging for Desk or Travel Use

At 800 mA per channel the charger draws modest power and generates minimal heat during normal operation. No active cooling is required, so the unit runs silently on a desk or in a laptop bag. The 15 W input ceiling keeps total energy draw low whether powered from a wall adapter, power bank or USB-C laptop port.

Questions about this item

How long will the 2300 mAh cells actually run a Brother DS820W or DS920DW scanner?

The 8.51 Wh lithium-ion batteries replace the original LD0665001 and AP-1908 packs, giving comparable run-time to the factory cells in the DS820W and DS920DW scanners.

What does the 5 V 2-3 A USB input limit mean for charging speed?

The LTD2 charger draws up to 15 W from any USB-A, Micro-USB or Type-C source and delivers 4.2 V at 800 mA per slot, so two batteries charge simultaneously at that rate.

Will the charger and three batteries fit inside the scanner’s carry case?

The pack measures 5 x 3 x 3 inches, a compact footprint that slides into most scanner bags alongside the DS820W or DS920DW unit.
