SAFETY HAZARD WARNINGS FOR LITHIUM ION BATTERY USE


You must read these instructions prior to using lithium ion battery.

Rechargeable Lithium Ion batteries are potentially hazardous and can present a serious FIRE HAZARD if damaged, defective or improperly used.

Larger Lithium batteries and those used for industrial use involving high discharge current and frequent full discharge cycles require special precautions.


A fire is most likely to occur during the following circumstances:

  • The battery has been fully discharged and then not recharged for a long length of time. Batteries must be recharged within 24 hours of a full discharge.
  • Battery is attempted to charge at a temperature at or below 40°F (4°C). Charging at or below 40°F (4°C) can possibly lead to a fire or explosion during charging.
  • Battery has been exposed to water. Exposure to liquids can cause internal corrosion or damage to the cells or to the circuit board, which can lead to a fire during recharging.
  • Operating a battery that has been dropped or damaged.
  • Using a charger other than a standard 5V USB charger.

Charging:

The following recommendations should also be followed when charging Lithium Ion batteries to ensure the avoidance of catastrophic fire or explosion.

  • Charging should be performed in a fire-safe area, away from children or pets. For highest safety, it is recommended to place charging battery pack in a metal trash can with lid placed on a non-flammable surface. Never charge batteries unattended, or on or near flammable objects such as carpet, furniture, wood or vinyl floors, or curtains.
  • Charging should be performed at a temperature above 40°F and below 110°F

(4°C and 43°C). Never charge below 40°F (4°C).

  • Do not attempt to charge a battery that is swollen or bulging. Use only supplied charging cables and connections. Inspect cables and connections for damage. Do not allow the charging polarity to be reversed or short-circuited. If shirt is connected during charging, the shirt should be switched off.
  • If any of the above circumstances occur, observe the battery in a safe place for at least 15 minutes after charging is complete to ensure no chemical reaction will cause a fire.
  • A healthy battery should only get a little warm to the touch during charging. If the battery becomes hot, smokes, swells, or gives off an odor during charging or use, turn off immediately and contact the manufacturer.

Operation and storage:

  • Batteries may be safely used at temperatures between 4°F and 140°F (-20°C and 60°C).
  • Batteries should be stored at temperatures between 40°F and 80°F (4°C and 27°C) for best battery life and safety. Higher storage temperatures increase the self-discharge rate and can reduce battery life and increase the possibility of catastrophic failure after long out of range storage.  Never store batteries at temperatures higher than 170°F (76°C) as this can potentially result in fire.
  • Batteries may be stored at 100% charge if used often. However, for maximum life, batteries infrequently used should be stored at 30%-70% charge. Charge battery to around 50% by checking the indicator lights.

Safe Disposal of battery pack:

  • Lithium Ion batteries contain elements that may pose health risks to individuals if they can leach into the groundwater. In some countries, it may be illegal to dispose of these batteries in standard household waste. Many recycling facilities exist that process lithium ion batteries. In the United States and Canada, a large network of over 30,000 battery drop-off locations may be found at www.call2recycle.org.

To prepare the battery to be safe, apply tape over any exposed connectors to prevent the accidental shorting of the positive and negative terminals of the battery during transport. Place each battery into its own plastic bag, seal the bag, and deposit the battery into the recycling container. Never dispose of the battery in a fire or incinerator, as the battery may catch fire and explode.
