SLA Battery Charging and Maintenance

Sealed Lead Acid batteries are one of the most common battery types; however, most people don’t think about them until it's too late. Proper charging, maintenance, and storage practices are crucial to the life and operation of your battery. If you notice a drop in performance, it may be time to replace your SLA battery.

Best Charging Practices

Use charger that provides proper voltage for the battery

Make sure you are using a charger that provides the proper voltage for your battery. Gel batteries require a different charge voltage than other sealed lead acid batteries.

Overcharging kills batteries

Do not speed up charging time or increase voltage for a fast charge. This will result in overcharging the battery. Batteries that are overcharged will over heat. Excessive heat can destroy a battery in as little as a few hours. Overcharging kills batteries.

Undercharging shortens battery life

Do not use a lower charging voltage than required for your battery. By doing so, the battery will never be fully charged. Undercharging leads to reduced capacity creating a battery that needs to work harder than fully charged batteries. Undercharging and overworking leads to shortened battery life.


Best Maintenance Practices

Recharge after each use and store battery fully charged

For maximum battery life and performance, batteries should be recharged as soon as possible after each use. Batteries should be stored in a fully charged state. Storing in a discharged state will kill the battery.

Disconnect charger once fully charged

Disconnect the charger after the battery has been fully charged. Continuous over charging or under charging is the worst thing for a SLA battery.

Check battery for corrosion or deformation

Check the battery terminals for corrosion and/or battery deformation. A deformed battery or corrosion on the terminals is subject to failure.

If battery run-time becomes short, bring your battery into any of our locations for testing.


Best Storage Practices

Store in cool, dry place

Batteries should be stored in a cool, dry place. Optimal temperature is 68 degrees F. If stored at elevated temperatures, shortened battery life will most likely occur.

Do not store in a discharged state. Charge batteries every couple months

Batteries should not be stored in a discharged state. Doing so will result in shortened battery life. Charge the battery every couple months when in storage or more frequently if stored in high temperatures.


Choosing the Correct Replacement

There are four main types of sealed lead acid batteries. Each battery type has been specifically designed to best perform under certain conditions. The harder a battery has to work, the sooner it will fail. Therefore, the type of SLA battery that you should use is based on your application. Not sure which battery you need? Bring your battery into your local store. We'll test it to make sure you need a new one, and we'll identify the proper replacement for you.
