Two 12-volt, 7-amp batteries connected in parallel provide what voltage and amp-hour rating?

Explanation:
When connecting batteries, parallel keeps the voltage the same while adding the capacities. So two 12-volt batteries each rated at 7 Ah put in parallel give 12 V in total and 7 Ah + 7 Ah = 14 Ah. That matches the stated answer. If instead they were wired in series, the voltage would double to 24 V, but the capacity would remain at 7 Ah.
