BATTERIES

New battery packs reach full loading capacity after 4-5 
chargings and dischargings. Battery packs which have 

not been used for some time should be recharged 
before use.

Temperatures in excess of 50°C (122°F) reduce the 
performance of the battery pack. Avoid extended 
exposure to heat or sunshine (risk of overheating).

The contacts of chargers and battery packs must be 
kept clean.

For an optimum life-time, the battery packs have to be 
fully charged, after use.

To obtain the longest possible battery life remove the 
battery pack from the charger once it is fully charged.

For battery pack storage longer than 30 days:

Store the battery pack where the temperature is below 
27°C and away from moisture

Store the battery packs in a 30%-50% charged 
condition.

Every six months of storage, charge the pack as 
normal.

MAINTENANCE
