Hints
You can use an optional battery pack and install it in the
UltraBay and have two battery packs for longer
battery-powered operation.
When you have two battery packs installed in the computer
and start charging, charging starts on the battery pack in the
battery pack bay. When it is fully charged, charging starts
on the battery pack installed in the UltraBay.
If the battery pack is new or has not been used for a long
time, it will not be fully charged with only a single charging.
You will have to discharge and recharge it three to six times
to maximize battery operating time, and to keep battery
status accuracy.
The Quick Charger is available as an option to charge the
battery packs.
