Operating Manual 

 

 

Battery Life: 

 

Application of the Battery Protector 40 can prolong the battery life considerably. This is obtained by observation of the 
following general rules: 

 

In contrast to other battery types, batteries on lead basis 

do not have any

 harmful memory effect. Consequently: In case of 

doubt, partially discharged batteries are to be 

charged fully 

as soon as possible.  

 

Store only fully charged batteries 

and recharge them periodically, particularly in case of used (older) batteries and higher 

temperatures. Sulphation of the battery plates due to total discharge is to be prevented by immediate charging, particularly 
in case of low and high ambient temperatures.  
Observe the instructions and technical leaflets of the battery manufacturers. 
Keep batteries cool; choose an appropriate location for installation.
