Where are the nickel-cadmium (nicad) batteries located?

• A. Under the seats in car B only
• B. Between the cars
• C. Under the seats in car A only
• D. In the engine compartment

Answer: (C)

Nickel-cadmium battery packs are placed where they stay cool enough, are protected from shocks and fluids, and are easy to access for inspection and replacement. In this scenario, the pack is located under the seat in car A. This position keeps it away from the engine and heat, reduces exposure to vibration, and allows straightforward service access by lifting the seat. Putting the battery in the engine compartment would subject it to high heat and more vibration, which can shorten battery life. Locating it between the cars would be insecure and easily damaged during movement or coupling, and placing it under the seat in car B would misplace the pack from its intended system, complicating maintenance and operation.
