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.

Example: When two 12 V batteries, each with a capacity of 88 Ah,
are connected in series, voltage will be 24 V and the total capacity
88 Ah.
