IMPORTANT INFORMATION FOR 
RECHARGING HOT BATTERIES

Under lengthy continuous use, the bat-
teries in your battery pack will become 
hot. You should let a hot battery pack 
cool down for approximately 1 hour 
before attempting to recharge. When 
the battery pack becomes discharged 
and is hot, this will cause the red light 
on your battery charger to flash. When 
the battery pack cools down, red light 
will glow continuously indicating fast 
charging mode, 1 hour charge time. 
Once the battery pack cools down, it 
will recharge battery pack in fast
charging mode as normal.
