when charging two 12-volt batteries in

parallel it is important to remember

that the voltage stays the same but the

amp our capacity of the battery system

increases this is important because the

increase in battery capacity will affect

charging time for example if you have a

40 amp hour automotive battery and a G

3500 it will take you roughly seven

hours to recharge the battery if you add

another battery in parallel the charging

time will increase to around 13 hours

here are some useful information when

charging two batteries to 12-volt

batteries form a parallel connection

when the batteries are connected

negative two negative and positive to

positive the resulting system maintains

a total output of 12 volts but increases

the overall capacity the batteries can

be charged at the same time by
