Digital Solar Gel batteries use electrolyte that is saturated in a GEL form instead of liquid electrolytes between the plates. GEL Batteries, being viscous in nature, assures a high level of recombination of generated water vapor molecules formed during charging and discharging processes – keeping the maintenance free. These Solar Gel Batteries are deep cycled batteries which makes them perfect for Solar applications. GEL electrolyte is especially suited for a high-temperature operating environment, giving these batteries an additional advantage over other batteries in outdoor solar applications.
