5 Capacity and Service Life
Aquagen recombinators are overload-proof, i.e. there is no risk of the plastic materials of
the aquagen recombinator or the battery being damaged due to overheating for voltages up to
2.7 V/cell (boost or equalisation charges with I const). The function of the recombiner will be not
restricted in this case. The aquagen recombiner is optimized in the working range up to 2,4 V and
achieves the highest efficiency and the maximum service life.
For cyclic applications, we therefore recommend the use of the HOPPECKE electrolyte-circulating
pump sun.air instead of the aquagen recombinator. When using the aforementioned pump, it is
also possible to reduce the water consumption significantly.
Explanation:
Boost charges and equalisation charges: charges with I/U curve, voltage limitation at max.
2.4 V/cell in the constant voltage phase.
An initial charge is also a boost charge. It is realised with an I/U curve with a max. voltage of
2.4 V/cell. As an alternative, it is also possible to charge with an I- (constant current) or a
W- (constant power) curve. In doing so, charging voltages of up to 2.6 V/cell are reached.
Attention!
Before charging with voltages > 2.4 V/cell, we recommend the removal of the aquagen recombi-
nators. In order to avoid contaminations of the caps of the battery cells/blocks, the bayonet plugs
with the labyrinth inserts have to be inserted into the cell openings before beginning to charge.
When charging with higher currents over a corresponding period of time, condensation of water
vapour outside the aquagen recombinator might occur. The water drops which will develop in this
case are not an indicator of a fault or a leakage in the system.
Attention!
If aquagen recombinators are, for whatever reason, removed from the cells/blocks, the aquagen
recombinators must be deposited in a vertical position by analogy with the operating position (do
not place recombinators on the side). A corresponding tray “aquagen Stand” is included in the
scope of delivery.
Attention!
If the ambient air temperature at the installation location of the battery can drop below 5 °C, aqua-
gen recombinators must not be assembled or operated. Otherwise openings inside the aquagen
might freeze and hence gas can not escape from the cell anymore. In consequence the battery
cell jar might be damaged due to excess pressure.
