Replacement Ni-MH battery pack

This 14.4 V, 360 mAh Ni-MH pack replaces the original Brother PocketBook300 battery. It matches the LB4707001, PA-BT-300, SB-BT500-N, PJ-4844A and PA-BT-500 part numbers. The pack measures 173.0 × 24.42 × 13.21 mm and weighs 258.7 g. Safety circuits protect against over-charge, over-discharge, over-voltage and short circuits.

Who this suits and who it does not

It fits owners of a PocketBook300 device whose original pack has lost capacity. Buyers needing a different voltage, a higher capacity, or a lithium chemistry should look at other options. The unit is certified to ISO 9001, RoHS, CE, UN 38.3 and MSDS standards.

Deciding specification

The critical figure is the 14.4 V nominal voltage combined with the 360 mAh capacity; the device will only operate correctly with this exact voltage and connector layout. Confirm the model and part number before ordering.
