Maintenance and storage are vital factors for the life-span of all types of batteries. Make sure to read the information printed on the front face of the batteries.


Never use a lead-acid charger for lithium batteries and vice versa.

Increase charging intervals according to the age of the battery. Older batteries need to be charged more often and trickle-charged when stored for a long time.


Please note the storage temperatures written on the front face of the batteries. Lead-acid can be stored with 100% capacity whereas lithium batteries should be stored with approximately 50% of the total capacity.

Determination of the battery age

The code on the top of the battery gives information about the production year and month, please check the first digit and letter to identify the production date:

Digit 1123456789   



For non-prefilled batteries the production date refers to the plastic block of the battery, it does not give information about the date when the battery was filled.
