4.When the charged battery pack is needed, remove the battery pack from the charger.

When the battery charger is not in use, disconnect the DC power source.

Operational Considerations

Issues to consider when you use the FMW51BC1 battery charger are discussed as follows:

You can insert up to two battery packs at a time in the battery charger. When charging two battery packs, you can insert or remove either battery pack independently.

The battery charger only charges one battery pack at a time. When two battery packs are inserted in the charger, the battery pack installed first is charged first.

The battery charger will indicate a full charge level and will not begin charging the battery pack if the battery pack charge level is 90% or higher when the battery pack is initially inserted in the charger. This prevents the battery pack from being overcharged.

When you remove the battery pack from your pen tablet, always insert a charged battery pack in the pen tablet to replace the one that you removed, or apply DC power.

The FMW51BP1, FMW29BP1, FMW29BP2, and FMW43BP2 battery packs use lithium ion battery cells which have no “memory effect.”You do not need to discharge or “condition” the battery pack before charging.

Battery Pack Charge Time

The approximate maximum amount of time needed to charge a fully discharged battery pack to the 90% level is shown in the following table. Note that when two battery packs are installed in the charger, they are charged sequentially (starting with the battery pack that is installed first).
