Is 12 volt battery same as 23a battery?
If the "A" in 23A refers to ampere (in which case it would be
written in uppercase), then no; voltage and current (the number of
amperes) are unrelated to one another.If 23a is the model number of
the battery, you would just have to check the specifications of the
battery (it should normally have a metal plate with the
specifications on it), to check whether the voltage is 12 volt. Car
batteries usually have a voltage of 12 volts.
