How to Replace the Battery in a Nissan Sentra

Since 1982, the Nissan Sentra has performed moderately well in the marketplace. It's a reliable mid-size car and is as durable as most Nissan products. The battery is a 12-volt that can be replaced with most brands. Nissan, however, recommends that you use genuine Nissan parts.

Lift the battery out of the compartment. Keep your gloves on at all times to avoid getting acid on your hands. Safely dispose of the battery at an auto parts store or a recycling center.

Use a wire brush to clean the surface that holds the battery. Wipe it down with a damp cloth and let it dry.
