Replacement Battery for Becker HJS 100 GPS

This lithium-ion cell replaces the original battery in Becker HJS 100, HJS-100 and Map Pilot navigators. It delivers a capacity of 900mAh at 3.7 volts and weighs 19.4 grams. The unit is built to the same electrical and physical specifications as the factory pack and carries ISO9001, RoHS and CE certification. It suits owners who need a direct drop-in power source for those specific models.

Installation Notes and Common Issues

Many online videos demonstrate the fitting process and most users find it straightforward. The critical step is ensuring the connector seats fully before closing the device. A new cell reaches its rated runtime after two or three full charge cycles. Using a low-quality charger can shorten service life, and the pack must never be disassembled, exposed to fire or water, or stored above 60 degrees Celsius.

Sustained Operation Behaviour

The integrated protection circuit guards against overcharge, over-discharge, over-voltage and short-circuit events during long journeys. Shock-absorbing foam in the packaging helps the cell survive transit without damage. Buyers who require a higher capacity than 900mAh or a different voltage should look elsewhere, as this model matches the original 3.33Wh specification only.

What comes in the package and do I need to buy any extra parts to fit this battery?

The box contains one Cameron Sino lithium-ion replacement cell (900 mAh / 3.33 Wh, 3.7 V) with a pre-fitted decoded chip and protective foam for transit. No additional components or tools are required for installation.

Which version of this battery matches my Becker Map Pilot — the 338937010208 or the HJS100 part number?
