SLA Battery Charging and Maintenance

Proper charging, maintenance and storing practices are just as important to the life and operation of your SLA battery as choosing the right battery type for your application. Your local Batteries Plus Bulbs can help to identify the best charger for your battery and usage.

Best Charging Practices

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.

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.

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

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

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

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.

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.
