4 Lead acid batteries with armour plated cells and liquid
electrolyte
4.1 Description
Jungheinrich traction batteries are lead acid batteries with armour plated cells and
liquid electrolyte. The names of the traction batteries are PzS, PzB, PzS Lib and PzM.
Electrolyte
The rated density of the electrolyte assumes a temperature of 30°C and the rated
electrolyte level is fully charged. Higher temperatures will reduce, lower temperatures
will increase the electrolyte density. The adjustment factor is ± 0.0007 kg/l per K, e.g.
electrolyte density 1.28 kg/l at 45°C corresponds to a density of 1.29 kg/l at 30°C.
The electrolyte must conform to DIN 43530 Part 2 purity regulations.
