Operational Considerations
Issues to consider when you use the FMW51BC1 or FMW51BC2 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, FMW43BP2 and FPCBP48 battery packs use lithium ion battery cells which have no “memory effect.” You do not need to com- pletely 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 sequen- tially (starting with the battery pack that is installed first).
