you can just check it properly... (on every battery volt is surely given...)
The 12 volt battery has double the electromotive force of the 6 volt. Electromotive force is measured in volts.

The main difference between a 12-volt armature and a 24-volt armature is the voltage rating at which they operate. A 12-volt armature is designed to run on a 12-volt electrical system, while a 24-volt armature is designed for a 24-volt electrical system. This difference determines the power and speed capabilities of the armature when used in electrical devices.
One is 9 volts and the other is 12 volts. They do not interchange!
lets think ones more powerful than the other......12<18....only my opinion
The main difference between a 12-volt and an 18-volt drill is the power output. An 18-volt drill generally provides more torque and power, making it suitable for heavier-duty tasks and harder materials. In contrast, a 12-volt drill is lighter and more compact, making it more convenient for lighter tasks and overhead work.
They can look the same, so I would take the number from it and have it looked up at a parts store using there BUYERS GUIDE.
It'll say 6v or 12v written right on the battery.
connect + to + and - to - and connect the load between the two + and the two -
The difference is 12.
12 volt
