Classic OPzS

Industrial Batteries – Classic OPzS 

Energy storage for economical safety.

Developed from Experience 

produced for safe power supply. 

Specifications 

Classic OPzS batteries have been 

proven energy suppliers for decades, 

which captivate in robustness, extreme 

long design life and reliability 

Very high operationally reliability 

under rough operating conditions 

Low maintenance due to reduced 

antimony in the alloy and high 

electrolyte reserve 

Nominal capacities from 50 Ah to 

3350 Ah C10; up to 12000 Ah on 

request 

15 years design life at 20°C 

ambient temperature 

(80% remaining capacity from C 10 ) 

Also designed for cyclic 

applications 

Containers made from high-quality 

transparent SAN plastics 

Tubular plates in bloc and single 

cell version 

Also available in dry charged 

condition with separate electrolyte 

Low gassing due to antimony 

alloy < 3% (VDE 0510 T2) 

Conforms to DIN 40736 and 

DIN 40737 T3 

Electrolyte: diluted sulphuric acid 

d N = 1.24 kg/l 

Optimised plate design produces 

increased capacities compared 

to DIN 

Completely recyclable
