Direct Replacement for Brother PocketBook PJ Series

This 14.4V Ni-MH battery pack replaces the original LB4707001 and PA-BT-500 cells across the PJ-520, PJ-522, PJ-523, PJ-560, PJ-562, PJ-563, PJ-622, PJ-623, PJ-662, PJ-663 and PJ-673 printers. It is built for mobile professionals who need a fresh power source for existing hardware. The 360mAh capacity matches the factory rating for compatible models.

Thermal Behaviour and Power Draw

Ni-MH chemistry runs cool during typical print jobs and does not require active cooling. The pack delivers 5.18Wh at 14.4V, drawing only the current the printer requests. Overcharge, over-discharge, over-voltage and short-circuit protection circuits limit heat build-up and protect both the battery and the host device.

Certified Safety and Ready-to-Use Fit

The pack carries ISO9001, RoHS, CE, UN38.3 and MSDS certifications confirming toxic-free materials and transport safety. Dimensions of 173.0 x 24.42 x 13.21mm and a weight of 258.7g match the original form factor so the battery slides into the compartment without modification. No extra cables, chargers or software are bundled.

Questions about this item

How do I install the battery in my PocketBook PJ-673 and what step is often missed?

Slide the pack into the compartment until the latch clicks; the step often missed is pressing the release tab fully before pulling the old pack out.

What maintenance or replacement will this 360mAh Ni-MH pack need later?

Expect capacity to fade after roughly 300–500 charge cycles; plan on a replacement pack when run-time drops below half of the original 5.18Wh.

What limit appears first during sustained printing with this 14.4V pack?

Voltage sag under continuous load triggers the printer’s low-battery shutdown before the 360mAh capacity is fully used.
