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 used.
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.

BATTERY PACK PROTECTION LI-ION BATTERY

The battery pack has overload protection that protects it
from being overloaded and helps to ensure long life.
Under extreme stress the battery electronics switch off the
machine automatically. To restart, switch the machine off
and then on again. If the machine does not start up again,
the battery pack may have discharged completely. In this
case it must be recharged in the battery charger.
Thermal Overload Protection:
Overheated cells will reduce performance, run time and life.
Overheating can occur from battery packs being exposed to
very hot environments or from the tool they are powering
being over-worked.
The control electronics will automatically shut down the
battery pack to protect the cells which in turn protects the
electronics and motor within the tool.
The battery pack will automatically shut itself down again
should the temperature condition remain high when the
trigger is pulled again.
The system will continue to shut the battery pack down until
the temperature is returned to a safe operating level.
Current Overload Protection:
The control electronics will instantly shut down the battery
back when excessive current draw is detected - protecting
both the battery cells and the motor of the tool.
Releasing the trigger will reset the battery pack each time.
Individual Cell Monitoring:
The control electronics constantly check each individual cell
and automatically adjust its charge and discharge
requirements accordingly.
This systems maximises individual cell life whilst ensuring
that the battery pack is delivering peak performance to the
tool at all times.
INTENANCE
