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.
It's possible. Not likely to be the battery itself it that happens, though.
Nothing as long as it was a 12 volt battery.
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.
