GBA 10.8V 1.5Ah battery
It is replaced by the GBA 12V 1.5 Ah battery.
The GBA 10.8V 1.5 Ah is Lithium Ion battery pack for the 10.8 volt battery system manufactured by Bosch.
When the GBA 10.8V 1.3 Ah was discontinued the 1.5 Ah became the smallest capacity battery in the Bosch 10.8V battery system.
In North America this battery has the model name BAT412.
This product is marked as discontinued because in 2017 it was renamed to GBA 12V 1.5Ah when the 10.8 volt battery system was rebranded to "12V max".
