OPzS Solar batteries 910

Long life flooded tubular plate batteries
Design life:  Over 20 years at 20ºC,  Over 10 years at 30ºC and Over 5 years at 40ºC.
Cycling expectancy of up to 1500 cycles at 80% depth of discharge.

Low maintenance
Under normal operating conditions and 20ºC, distilled water has to be added every 2 – 3 years.
Dry-charged or ready for use electrolyte filled
The batteries are available filled with electrolyte or dry-charged (for long term stocking, container transport or
air transport). Dry charged batteries have to be filled with diluted sulphuric acid (density 1,24kg/l @ 20ºC).
The electrolyte may be stronger for cold- or weaker for hot climates.
