There are two main types of UPS batteries, sealed lead acid (SLA) or valve regulated lead acid (VRLA). SLA batteries contain a layer of liquid inside the case, while VRLA batteries do not. The advantage with SLA is that the battery can be checked and topped up with distilled water without needing to open it. VRLA batteries do not have this safety feature.
Many UPS batteries use SLA technology. They typically contain 2% of sulfuric acid and 96% of distilled water. The remaining 2% is made up of material added to stabilize the electrolyte. The SLA battery should be fitted with caps on the top and bottom of the case for safety reasons, and these should be securely fastened when you are working with it.
Replacing a bad battery in an APC UPS device may be a simple process if you know what type your device uses. Replacing VRLA batteries on a UPS customer device may take some specialized equipment and training.
