3.The constructions
1. Positive electrode plates
Positve plates are made of lead –calcium alloy with special chemical fromula
2. Negative Electode plates
Negative plates are made of lead – ehemical fromula
3. separator
The glass – fibre separator in HENDA SLA battery are made with advanced technology –this high porosity of the separators retains adequate electrolyte for reaction with active matterial of the plates .
4.safe valve
The valve system which operaters from 1 psi to 6psi (0.07-0.43kg/cm3) is designed to relaease excess gas and keep the internal pressure within the optmum range of safety .it protects the negative plates from contamination from oxygen in the air valve are 100%visually inspected during battery production
If the internal pressure is increased to an abnormal level during overcharge ,the safety valve ill be opened to release gas . it thus eliminates the danger of repture .once it has opened m it automatically closed in preparetion for future excessive increase in pressure.
