Auto Battery Maintenance Tips

Long, cold winters do a number on your vehicle’s battery. Dirt and rust make it hard for the engine to connect to the battery and crank over. With seasonal battery maintenance suggestions, you can keep your battery in great shape and avoid getting stranded by a car that will not start.

How to Inspect and CleanΒ a Car Battery

Have a look at the battery posts. If they’re coated with dirt or residue, your car may struggle to get your car started. To clean a car battery first, remove the battery terminals with a wrench. Take off the negative terminal first, then the positive terminal.

Pour corrosion removal fluid over the residue and let it soak in for a few minutes. Use a stiff-bristled scrub brush to remove residue from the battery posts. Also scrub the surface of the battery, which may become soiled. You might need to work in many rounds employing fresh corrosion removal fluid in between bouts of scrubbing, to completely clean the battery.

A homespun blend of baking soda and H2O will also work to knock loose corrosion, which can be a helpful replacement if you can not get out to purchase corrosion removal fluid because of a dead car battery.

After the battery appears clean, rinse it with H2O.

When you have cleaned the battery, check its charging amounts with a hydrometer, which is available for purchase at the local auto parts store. Hold the hydrometer up into the battery cell and squeeze the bulb on top to get a reading. A satisfactory battery will read between 1.265 in 80 F. If your battery yields a reading of 1.260 or lower, it needs to be replaced.

Note, this last step is not required for maintenance-free car batteries.

How to Replace a Car Battery

When your automobile battery is no longer dependable, it is time to replace it. To accomplish this, remove the battery terminals using your wrench. Begin with the negative terminal, as when cleaning. To pull the battery out, you’ll also have to loosen the hold-down clamp with your wrench. After everything is loose, you can pull the battery out by hand.

Push a replacement battery into position and use the clamp to secure it. Attach the positive battery terminal, and then the negative battery cable terminal. Tighten connections with the wrench. Tighter is better, as your motor may struggle to crank over and start if the battery slides around.
