How does curing affect the life of lead–acid batteries?
Curing and formation have a significant impact on the performance and service life of lead–acid batteries. Curing renders crystalline structure to the highly porous active material, which acts like a skeleton for the microcrystalline structure that is established during formation. A good bonding of the active material to the grid is also achieved.
How long does a battery cured for?
