Mission Helicopter-65E (MH-65E) Standardization Practice Test

Which statement is true regarding battery life when DC powered equipment is secured?

The DC system will shut down after 15 minutes DC power is only available for 30 minutes Battery life remains fixed at 30 minutes The battery life can extend beyond 30 minutes when DC powered equipment is secured

Correct Answer:

The battery life can extend beyond 30 minutes when DC powered equipment is secured

Explanation:

Battery endurance depends on how much power is being drawn from the DC system. When DC powered equipment is secured, you reduce or remove nonessential loads, which lowers the current drawn from the battery. The 30-minute figure is a baseline under typical conditions, not a hard limit. With less load, the remaining battery energy can last longer than 30 minutes. So, the statement that battery life can extend beyond 30 minutes when DC powered equipment is secured is the most accurate.
