Note for battery Usage

1.1 Prohibition

For avoiding battery leakage, heat radiating, explosion, below prevent tips should be taken care of:

  • Prohibition of disassembly or re-assembly;
  • Prohibition of short circuited battery;
  • Prohibition to use near hot source;
  • Prohibition of dumping of battery into water ,ocean or getting battery wet;
  • Prohibition of charging near fire or under sunlight;
  • Charge with specified charge according to charging requirement;
  • Prohibition of inserting nail into battery, hammering or stepping on foot;
  • Prohibition of throwing;
  • Prohibition to use with damaged or deformed battery

1.2 Attentions

  • Prohibit of using battery in sunlight, otherwise will cause over hot, firing, or function failure , life reducing;
  • Prohibit use near static place which over 64V;
  • Prohibit charge at temperature below 0℃ or above 60℃;
  • When use at first time, if has corrosion, or bad smell, or any other abnormal, please do not use.

No.
