Where are the batteries located?

• A. Left side of the front electronic compartment
• B. Right side of the rear electronic compartment
• C. Under the cockpit floor
• D. In the baggage compartment

Answer: (A)

Batteries on the ERJ-145 are located on the left side of the front electronic compartment. This placement keeps the primary power source next to the cockpit and near the main electrical distribution, which helps ensure quick access for maintenance and reliable power for essential systems during start and operation. It also minimizes heavy cable runs to the essential buses and keeps the batteries in a controlled electronics area rather than in cargo or aft locations. The other suggested locations would place the batteries in areas that are less practical for electrical power needs or safety, so they aren’t used on this aircraft.
