condition and does not indicate a problem. You can
recharge the battery cartridge fully after discharging it
completely and recharging a couple of times.

tool or battery cartridge which has been left in a location
exposed to direct sunlight for a long time, the charging
light may flash in red color. If this occurs, wait for a while.
Charging will begin after the battery cartridge is cooled
by the cooling fan installed in the charger. When the
temperature on battery is more than approx. 70°C, two
charging lights may flash in red color, and when approx.
50°C - 70°C, one charging light in red color.
