Safety Precautions:

Misusing the battery may cause the battery to get hot, explode, or ignite and cause serious injury. Be sure to follow the safety rules listed below:

  • Do not carry or store the batteries together with necklaces, hairpins, or other metal objects.
  • Do not solder directly onto the battery.
  • Do not place the battery in fire or heat the battery.
  • Do not place the batteries in microwave ovens, high-pressure containers, or on induction cookware.
  • Do not install the battery backwards so that the polarity is reversed.
  • Do not connect the positive terminal and the negative terminal of the battery to each other with any metal object (such as wire).
  • Do not penetrate the battery with nails, strike the battery with a hammer, step on the battery, or otherwise subject it to strong impacts or shocks.
  • Do not expose the battery to water or salt water, or allow the battery to get wet.
  • Do not place the battery on or near fires, stoves, or other high-temperature locations. Do not place the battery in direct sunshine, or use or store the battery inside cars in hot weather. Doing so may cause the battery to generate heat, explode, or ignite. Using the battery in this manner may also result in a loss of performance and a shortened life expectancy.
  • When charging the battery only use chargers that have specially been designed for use with lithium-ion batteries.
  • The temperature range over which the battery can be discharged is -10°C to 60°C. Use of the battery outside of this temperature range may damage the performance of the battery or may reduce its life expectancy.
  • If you are not planning on using the battery for about 6 months or longer, first charge it fully and then recharge it once a year. A lithium-ion battery that has been left empty for too long can no longer be charged.
