Volvo IPS650 - Starting Group Battery Capacity

Two batteries connected in series provide the same
capacity, but double the voltage. During charging,
each battery takes current from the charger. The total
battery voltage may not exceed the battery voltage
stated on the charger.
When two 12 V batteries are connected in series and
one of the batteries has a shorted cell, the voltage of
the two batteries will be around 23 V.
