12  Legal guarantee

In accordance with German statutory regulations, there is a legal guarantee on 

this product for the customer. 
The seller will remove all manufacturing and material faults that occur in the 

product during the guarantee period and affect the correct functioning of the 

product. Natural wear and tear does not constitute a malfunction. No legal 

guarantee can be offered if the fault can be attributed to third parties, unprofes-

sional installation or commissioning, incorrect or negligent handling, improper 

transport, excessive loading, use of improper equipment, faulty construction 

work, unsuitable construction location or improper operation or use. Legal guar-

antee claims shall only be accepted if notification of the fault is provided imme-

diately after it is discovered. Guarantee claims are to be directed to the seller. 
The seller must be informed before guarantee claims are processed. For 

processing a guarantee claim an exact fault description and the invoice/de-

livery note must be provided. 
The seller can choose to fulfil the legal guarantee either by repair or replace-

ment. If the product can neither be repaired nor replaced, or if this does not 

occur within a suitable period in spite of the specification of an extension period 

in writing by the customer, the reduction in value caused by the fault shall be 

replaced, or, if this is not sufficient taking the interests of the end customer into 

consideration, the contract is cancelled.
Any further claims against the seller based on this legal guarantee obligation, in 

particular claims for damages due to lost profit, loss-of-use or indirect damages 

are excluded, unless liability is obligatory by law.

13 Appendix

Glossary

A number of specialist terms are used in this manual which are briefly explained 

as follows:

Charging current factor   Ratio of the maximum charging current to the set bat-

tery  capacity.  A  charging  current  factor  of  0.3  with 

100 Ah means that the charging current is 0.31 A/Ah 

x 100 Ah = 30 A.

Pre-charging  

 Pre-charging reduces sulphation in damaged batteries, 

and is activated if batteries have a low voltage upon 

connection of the charger, and only accept a low cur-

rent after charging begins. 

Main charging 

 In this phase, the battery is charged to approximately 

90% of its capacity with the set maximum current.

Recharging 

 Once the end-of-charge voltage is reached, recharging 

begins, in which the battery is charged to 100% of its 

rated capacity. 

Charge optimisation 

 This causes acid restratification and thus equalises the 

acid density in the individual cells of a battery.

Trickle charging  

 After charging has finished, trickle charging keeps the 

battery fully charged for as long as it is connected to 

the charger.
