Typical Self-Discharge of VRLA Batteries at Different Temperatures

A fully charged batteries shelf life will discharge at approx;

2% per month when stored at 8˚C/46˚F 3% per month when stored at 20˚C/68˚F 5% per month when stored at 30˚C/86˚F 10% per month when stored at 40˚C/104˚F

Batteries kept in storage while discharged will not perform as intended when put into service. Battery inventories should be constantly checked and re-charged when necessary. A Battery in storage should never be allowed to discharge more than 45-50% of its original capacity.
