Part 1. About the charger option
The IBM ThinkPad Li-Ion Multiple Battery Charger (hereafter called charger option in
this manual) is a new type with two unique connectors. The unique connector has a
holder that holds the connector firmly regardless of the thickness of the battery pack.
Owing to this unique connector, you can use the charger option for following
ThinkPad battery packs and bay battery packs.
ThinkPad A2x series computer
ThinkPad T2x series computer
Note: For other IBM computers, contact your IBM authorized dealer or IBM
marketing representative to determine if the batteries for those models can
be used with this charger option.
You can charge one battery pack at a time with the charger option. If you connect
two battery packs to the charger option, they are charged in the order in which they
are connected. The charger has indicators that show the charging status.
You need the ac adapter of the ThinkPad computer to use the charger option.
This package includes the following items:
