What is a common maintenance task related to a vehicle’s battery?

• A. Replacing the battery every year
• B. Cleaning corrosion from terminals
• C. Adding water to the battery
• D. Checking tire pressure

Answer: (B)

Cleaning corrosion from battery terminals is a common maintenance task because corrosion can impede the electrical connection between the battery and the vehicle’s electrical system. Over time, a build-up of corrosion can lead to decreased performance, difficulty starting the vehicle, or even complete failure of the battery to provide power. Keeping the terminals clean ensures optimal current flow and extends the life of the battery.

In contrast, replacing the battery every year is not practical or necessary for most vehicles, as batteries can last several years with proper care. Adding water to the battery is only relevant for certain types of batteries, such as lead-acid batteries that are not sealed; many modern batteries are maintenance-free. Similarly, checking tire pressure is essential for vehicle safety and efficiency but is unrelated to battery maintenance.
