BATTERY TEMPERATURE PROTECTION
This charger has a battery temperature protection
feature. When the charger detects a battery pack that
is too hot (the light will flash red), its internal fan will
rapidly cool the battery to the correct temperature.
When the charger detects a battery pack that is too
cold (the light will flash red), it automatically activates
the protection circuit, and suspends charging until
the battery pack has reached the correct temperature
. The charging process will then automatically begin
(the light will flash green). This feature ensures
maximum battery life.
LEAVING THE BATTERY PACK IN THE
CHARGER
If a fully charged battery pack is left in the charger,
the battery pack will enter a sleep low power mode.
IMPORTANT CHARGING NOTES:
1. For long-term storage, please keep the
battery pack at 40%~60% state of charge. It
is suggested to check the battery power level
regularly. During long term storage, battery should
be charged and discharged every 3 months.
2. Never freeze your charger or immerse charger in
water or any other liquid.
3. When the battery pack fails to produce sufficient
power on jobs that were previously done easily,
please recharge your battery, do not continue to
use under this condition.
You may charge a partially used pack whenever
you desire with no adverse affect on the battery
pack.
