1998-2001 Nissan Altima Battery Replacement (1998, 1999, 2000, 2001)

Introducción

This guide will show you how to replace the battery in a 1998-2001 Nissan Altima.

If turning the key in the ignition doesn't turn your car on, or the battery light turns on in the dashboard, it may be time to change out your car battery. Typical car batteries can have a 3-4 year lifespan but will vary from driver to driver; when batteries with corrosion aren't cleaned it can lead to serious damage to the clamps/terminals and a dead battery renders the car unusable.

Before using this guide, make sure to run through any other possible reasons for the car not turning on with the use of an OBD reader (car diagnostic scanner).

When following this guide, it's crucial to ensure that the engine is completely shut off to avoid injuries; additionally, make sure to never leave the wrench on the car battery. When not in use, place it to the side or in your pocket. If changing the battery doesn't allow your car to start it's recommended to run an OBD reader to identify further issues or take it to a mechanic for professional help.

Remove the key from the ignition, make sure the engine is off, and engage the parking brake before beginning this repair.
