Care and Maintenance

Maintenance Instructions

  • Install this battery in a dry and well-ventilated environment. If the storage ambient temperature is too high or too low, it will affect the self-discharge rate of the battery  and accelerate the natural aging of the battery. It is recommended that the storage temperature is 15°C – 35°C (59°F-95°F), and keep the battery away from water sources,  heat sources, and other metal objects.

  • If the battery is not used for a long time, it is recommended to store the battery properly and keep the battery in a half-charged state (50% SOC).
    It is recommended to discharge the battery to 30% every three months, and then recharge it to 60%.

  • For safety reasons, do not store this battery in an environment where the temperature is higher than 35°C (95°F) or lower than 15°C (59°F) fora long time.

  • To prolong the service life of the battery, it is recommended to use the battery in an environment with a temperature of 15°C-35°C(59°F-95°F).

  • When the battery temperature is lower than 0°C (32°F), the battery cannot be used for charging. When the battery temperature is lower than -10°C (14°F), the battery  cannot be used for discharging.

  • If the power level of the battery is lower than 1% after use, charge it to 60% before storage. If the battery has been idle for a long time when the power is seriously  insufficient, it will cause irreversible damage to the battery cells and shorten the service life of the battery.

  • If the battery has been idle for a long time and the power level is severely low, it will enter a deep sleep protection mode. In such a case, charge the battery before using it again.

Disposal

  • When conditions permit, be sure to completely discharge the battery before placing the battery in the designated battery recycling bin. This product contains batteries.  Batteries are dangerous chemicals and should not be disposed of in ordinary trash bins. For details, follow the local battery recycling and disposal laws and regulations.
  • If the battery cannot be completely discharged due to battery failure, do not dispose of the battery directly in the battery recycling bin, and contact a professional battery  recycling company for further processing.
  • If the battery cannot start after being discharged dispose of it according to local laws and regulations on battery recycling and disposal.
