The voltage is set by the number of cells, so a 6 v battery has four cells and a 9 v battery has six.
The size of the cells decides the capacity but not the voltage, so four big cells might be bigger than six small ones. The one with bigger cells has a greater amp-hour capacity.
you can just check it properly... (on every battery volt is surely given...)
No, it will overcharge the 6 volt battery.
Yes, it has twice the voltage power.
No
if it is any think over 1 volt it is not a cell battery it is just a 6 volt battery if you had a 1 volt then it would be a cell battery
Impossible to do with a single 6 volt battery.
Power or energy cannot be measured in volts. The only thing you can say is one - the 9 volt battery - has a higher voltage than the other, the 6 volt battery. If you are asking about the power or energy contained in a battery, then the amount iof energy it can supply depends mostly on its physical size that is determined by the battery "type".
Buying a six volt battery is better than 12 volt. If you buy the 6 volt takes up less power so it holds more.
If you are asking the question, can you charge a 6 volt battery with a 12 volt charger, the answer is no.
No, you cannot charge an 8 volt battery with a 6 volt charger. The voltage of the charger must match the voltage of the battery.
No. 4-AA batteries hooked together is a much smaller package than the 6 volt lantern battery.
can 6 ,12 volt battery be wire to make in to one 24 volt battery for solar use in home
