PRECAUTIONS FOR CHARGER
1. Always charge the battery at a temperature of 10 –
40°C. A temperature of less than 10°C will result in
over charging which is dangerous. The battery
cannot be charged at a temperature higher than
40°C. The most suitable temperature for charging
is that of 20 – 25°C.
2. When one charging is completed, leave the charger
at least 15 minutes before the next charging of
battery.
Do not charge more than two batteries
consecutively.
3. Do not charge the battery for more than 2 hours.
The battery will be fully charged in about 1 hour
and charging should be stopped when 1 hour has
elapsed from commencement. Disconnect the
charger power cord from the receptacle.
4. Do not allow foreign matter to enter the hole for
connecting the rechargeable battery.
5. Never disassemble the rechargeable battery and
charger.
6. Never short-circuit the rechargeable battery. Short-

7. Do not dispose of the battery in fire.
If the battery is burnt, it may explode.
8. Using an exhausted battery will damage the charger.
9. Bring the battery to the shop from which it was

Inserting metal objects or inflammables into the
charger air ventilation slots will result in electrical
shock hazard or damaged charger.
