PRECAUTIONS FOR CHARGER

1. Always charge the battery at an ambient temperature
of 0–40°C. A temperature of less than 0°C will result
in over charging which is dangerous. The battery
cannot be charged at a temperature greater than
40°C.
The most suitable temperature for charging is that
of 20–25°C.
2. Do not use the charger continuously.
When one charging is completed, leave the charger
for about 15 minutes before the next charging of
battery.
3. Do not allow foreign matter to enter the hole for
connecting the rechargeable battery.
4. Never disassemble the rechargeable battery or
charger.
5. Never short-circuit the rechargeable battery.
Short-circuiting the battery will cause a great electric
current and overheat. It results in burn or damage
to the battery.
6. Do not dispose of the battery in fire.
If the battery is burnt, it may explode.
7. Using an exhausted battery will damage the charger.
8. Bring the battery to the shop from which it was

becomes too short for practical use. Do not dispose
of the exhausted battery.
9. Do not insert objects into the air ventilation slots
of the charger.
Inserting metal objects or flammable into the charger
air ventilation slots will result in an electrical shock
hazard or damage to the charger.
