system due to the face that the high charging
speed. Therefore always charge the battery at a
temperature of 10 – 40°C for UC9SD, UC12SD, and
UC14SD and 0 – 40°C for UC14YFA. A lower
temperature than these specified ranges will result
in overcharging which will shorten the battery life.
The most suitable temperature for charging is that
of 20 – 25°C.
2. When one charging is completed, leave the charger
for about 15 minutes before the next charging of
battery.
Do not charge more than two batteries
consecutively.

If the battery is burnt, it may explode.
8. When drilling in wall, floor or ceiling, check for
buried electric power cord, etc.
