All batteries are subject to BattG. This only then does not apply if a battery is explicitly excluded.
Batteries are sources of electric energy from one or more non-rechargable primary cells or rechargable secondary cells from which chemical energy is won by direct transformation.
BattG also applies to
- Batteries that are installed in other products or are enclosed in other products
- Battery sets
A battery set is a group of batteries that are connected with each other in such a way or are built together in an outer housing that they form a complete unit that cannot be separated or opened by the end user.
