Which battery has higher ampere-hours?

Which battery has higher ampere-hours?

• A. APU Battery: 24 VDC, 43 Ampere-Hours
• B. Normal Battery: 24 VDC, 17 Ampere-Hours
• C. APU Battery: 24 VDC, 17 Ampere-Hours
• D. Normal Battery: 24 VDC, 43 Ampere-Hours

Answer: (A)

Ampere-hours measure how much energy a battery can store and supply at its rated voltage. Since all batteries in this scenario are the same voltage (24 V DC), you judge capacity by the Ah value. A higher Ah means the battery can deliver current for a longer period before it’s depleted. The 24 V DC battery rated at 43 Ah has more stored energy than the 24 V DC batteries rated at 17 Ah, so it provides the highest ampere-hours among the options.
