How to test for a weak cell in an SLA battery



If you are experiencing decreased range with an SLA battery, it may be due to a weak cell. Once you’ve ruled out some other things you can check the battery for a weak cell by testing the voltage of the 12-v batteries inside of the larger 36v or 48v pack.

Be very careful when doing this, as you are removing the protective covering from the battery and modifying it. Call us up and ask first to make sure this is a good idea. It will probably void your warranty to do this if you battery is still under warranty, so check in with us first!
