It heats up very hot and may explode.
You will destroy the battery and be buying a new one.
Current will go up by a factor of 6 times in that scenario.
You cannot charge it connected backwards. You will destroy the battery.
Nothing as long as it was a 12 volt battery.
It's possible. Not likely to be the battery itself it that happens, though.
Boom
V = IR, so if you double the voltage without changing the resistance, the current will also double.
If a 1.5 volt battery is replaced by a 9 volt battery in a circuit, the current flowing through the circuit will likely increase. This is because the higher voltage of the 9 volt battery will provide more electromotive force, pushing more current through the circuit, assuming the resistance remains the same.
The crl225 battery is just a standard 12 volt battery. You can get another version, or a replacement battery for this, for about $8 dollars from Amazon or eBay.
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
No, it will overcharge the 6 volt battery.
