Battery Replacement
How are battery issues diagnosed?
If the battery dies, there may be other factors in its demise. Cars that have the symptoms of a dead battery should be properly tested using a machine. This device will test every part of the starting and charging system.
If the battery's charge is too low, it will be recharged, retested and possibly replaced. Other parts, including the alternator, battery cables and wiring, may need repair or replacement, as well.
How is a battery replaced?
For most vehicles, battery replacement is typically fast and easy. First, apply the emergency brake, remove the keys from the ignition and turn off all electrical components.
Remove the negative battery cable first, followed by the positive cable. After removing both cables, loosen and remove the holding brackets. The battery will then be free for removal.
When installing the new battery, always connect the positive cable first, followed by the negative cable. This order is important to avoid damaging the computers or software in the vehicle.
Note that some vehicles place the battery in the trunk, the front or rear wheel well, or under the seats. In these instances, you may need to dismantle other components first.
RepairPal Recommendations for battery issues
We recommend using a battery rated identically to the original one. Using too small or too large of a battery will result in overcharging or undercharging, and will lead to repeated failure.
Can I replace the battery myself?
Replacing the battery is pretty straightforward for most cars. However, there is a risk of electrical shock or causing electrical damage to the car. That's why it's important to follow the right steps when replacing a battery.
If the battery's location is hard to get to, you may be better off have a trained technician handle the repair.
