Which action may extend the battery life beyond 30 minutes?

• A. Run DC powered equipment
• B. Securing DC powered equipment
• C. Power on more devices
• D. Increase load on the DC system

Answer: (B)

Reducing electrical load on the DC system extends battery life. When you secure DC powered equipment, you turn off or isolate devices that aren’t needed for the current operation, which lowers the current drawn from the battery. With less current draining the battery, its energy lasts longer, potentially pushing endurance beyond the usual 30 minutes. In contrast, running DC powered equipment, powering on additional devices, or increasing the load would increase current draw and shorten battery life. So the best practice is to secure nonessential DC equipment to conserve power.
