Automatic Refresh
The automatic refresh mode will equalise or balance
the individual cells in the battery pack at its peak
capacity. Battery packs should be refreshed weekly
or whenever the pack no longer delivers the same
amount of work.
To refresh your battery pack, place the battery in the
charger as usual. Leave the battery pack for at least
10 hours in the charger.

Hot/Cold Pack Delay

When the charger detects a battery that is too hot
or too cold, it automatically starts a Hot/Cold Pack
Delay, suspending charging until the battery has
reached an appropriate temperature. The charger
28
then automatically switches to the pack charging
mode. This feature ensures maximum battery life.
LI-ION BATTERY PACKS ONLY
Li-Ion batteries are designed with an Electronic
Protection System that will protect the battery against
overloading, overheating or deep discharge.
The tool will automatically turn off if the Electronic
Protection System engages. If this occurs, place the
Li-Ion battery on the charger until it is fully charged.
