Charge input from solar arrays sometimes is insufficient to keep the batteries fully charged. During sun-less days, batteries are discharged but not charged. These conditions result in battery operating in partial state of charge (psoc), cycling and deep-cycling. Also, solar systems are installed in open atmosphere exposing the batteries to extreme temperatures. Other lead acid batteries fail in such conditions due to sulphation, stratification, corrosion and plate shedding. Moreover, remote solar installations make water top-up difficult and costs money.
To meet such rigors of usage hbl introduces a maintenance free (no water top-up) tubular gel vrla battery with unbeatable combination of tubular plate and gelled electrolyte, which is a perfect fit for all solar applications.
