The pocket plate design, combined with the Nickel-cadmium (Ni-Cd) chemistry and valve regulated technology places the EnerSys PowerSafe VGL Ni-Cd Batteries in the lead with low maintenance batteries. The Ni-Cd technology provides exceptionally long life at extreme temperatures while the inherent extremely low maintenance feature is enhanced by the valve regulated design. Qualities which unquestionably make the Ni-Cd series of batteries an ideal choice for low rates of discharge over long periods.
The robust design provides an excellent resistance against electrical and mechanical stress, low risk of terminal degradation and a proven 20 plus year life. This combination along with proven use in service make the PowerSafe VGL battery the right choice for industrial applications, proven reliability and the highest safety integrity. The EnerSys PowerSafe VGL Ni-Cd batteries covers discharges of 1 hour to 100 hours.
