GBA 12V 3.0 Ah battery

The GBA 12V 3.0 Ah is Lithium Ion battery pack for the 12V Max battery system manufactured by Bosch.

With 3.0 Ah it is the highest capacity compact battery available in the battery system in 2021. Batteries with higher capacity contain double the amount of cells and are significantly bulkier and heavier.

Exterior

The battery pack contains three cylindrical 18650 cells that are grouped together upright so that the battery pack can fit inside a handle of a power tool.

The battery pack has a black plastic casing with recessed electrical contacts on top. On the bottom is a black plastic cap with latches on both side to retain the battery when inserted in a tool. On the front of the cap the Bosch logo is printed. On the bottom the text "12V 3.0 Ah Li-Ion" is printed.

When sold in North America the Bosch logo is smaller and the voltage and capacity are printed underneath it on the front instead of the bottom.
