Valve-regulated lead-acid batteries
Valve-regulated lead-acid (VRLA) batteries with gelled electrolyte appeared as a niche market during the 1950s. During the 1970s, when glass-fiber felts became available as a further method to immobilize the electrolyte, the market for VRLA batteries expanded rapidly.
Main Types of Lead-Acid Batteries
There are three main types of lead-acid batteries, namely sealed, flooded, and valve-regulated. They mark the evolution of a remarkable product, yet each still has a positive role to play. All manage explosive hydrogen and oxygen gases arising from electrolysis during charging, but the difference is the way they work.
