Like most automotive components, batteries have finite life spans. Luckily, salvage yards that sell used auto parts carry affordable replacements that still hold charge. When it’s time for a new unit, use the guide below to correctly swap out the old battery for a new one.

When to Replace a Lead-Acid Battery

In general, the component needs to be replaced every three years. It might continue to work for up to five years, but at risk of dying suddenly.

Ultimately, the expected life span depends on how much power the car consumes while driving. Running the AC, playing the stereo, and charging electronic devices are routine tasks that drain the energy more quickly. It’s best to look out for signs of power loss, such as dimmer headlights and slower engine starts, to ensure you have a new unit before the old one dies.

How to Replace a Car Battery

First, locate it. It’s usually in the vehicle’s engine bay, but older models have the battery compartment in the trunk or behind the seats. To remove it, loosen the terminals using a spanner. Lift the terminals and tuck them aside. Then, take off the clamp and lift out the battery. Put in the new unit, tightening the connections, and reconnect the terminals. Use gloves for your safety.

The dead battery is hazardous because it contains toxic and corrosive chemicals. Any leaks can result in explosions, chemical burns, and environmental contamination, so Connecticut law requires drivers to safely dispose of dead batteries. Luckily, there are several easy ways to do so. A salvage yard that sells used auto parts will accept it for safe recycling. Also, you can take it to a hazardous waste recycling center for disposal.
