Types and Designs of Lead-Acid Batteries
You can distinguish lead-acid batteries by their electrolyte
plate technology.
In PV installations, the following five types are com-
monly used:
Lead-acid gel batteries —These batteries are different from the traditional
lead-acid battery with grid plates. In this valve-regulated battery, suspended
electrolytes in a gel provide some advantages: mobility, reduced risk of spills,
and reduced maintenance. Other advantages of this type of battery include
no need for watering maintenance, higher cycle resilience, and fully sealed
leakproof housing. They also have reduced sulfation, little to no pr ...
