How do I add acid to the battery?
You should never seek to add acid to our sealed batteries. Our VRLA batteries are a closed system that works on a recombination principle. To produce a truly maintenance free battery it is necessary that the gasses generated during overcharge are recombined in a so called “oxygen cycle”.The theory is explained on page 4 of our Technical Manual. To access our Technical Manual please go to the Literature – SLA Batteries section of our website. Opening the battery will cause irreparable damage and void the warranty.
