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

Explanation:
Voltage adds in series while capacity stays the same. So two 12-volt, 7-ampere-hour batteries wired in series give 12 V + 12 V = 24 V, and the amp-hour rating remains 7 Ah because the current path is the same through both cells. The combined pack thus provides 24 V at 7 Ah. The other options describe either parallel connections (which keep voltage at 12 V but add amp-hours) or using only one battery, which doesn’t reflect the series arrangement.
