About Sealed Lead Acid Battery Maintenance

The oldest type of rechargeable battery is the sealed lead acid battery, which was invented in 1859. Today, it is most commonly used to start automobile engines. Proper maintenance is necessary to ensure the longest battery life possible. The good news is that this maintenance is typically minimal.

Monthly Monitoring

This type of battery is equipped with an electrolyte monitor that is part of the top of the battery. The small monitor features a circle that changes color, in the event of a problem. When the circle is green, the battery is functioning properly. However, when the circle is black or yellow this indicates that the charge is fading or something else is wrong.

It only takes a moment to look under the hood to notate the color of the circle. Doing so is the simplest way to see if the battery needs to be charged or if an alternator check is in order.

Removing Corrosion

The posts on a sealed lead acid battery get corroded very easily. This happens for more than one reason. One of the most common reasons is when gasses from the battery condense on the metal surface of these posts.

This powdery white buildup, which is known to shorten battery life, can usually be removed with equal parts of water and baking soda or with a small piece of steel wool.

Tighten the Battery Clamp

When checking for corrosion or after you have removed it, take a minute to make sure the clamp that holds the battery in place is secure. A loose battery has the potential to damage the cables or other engine parts.
