Care instructions


Correct usage and storage of the battery will prolong the capacity and battery life.

  • Charge the batteries on a regular basis (at least every 3 months) to prolong the battery life, even during summer when the batteries aren't regularly used.
  • Use the specified charger only. Using another charger may affect the battery life and can affect your safety.
  • Always disconnect the battery if the heated clothing is not used. Batteries that stay connected will still consume a small amount of power.
  • (Re)charge the battery only shortly before actual use (e.g. overnight), as a battery still loses capacity even if it is not enabled.
  • The battery does not need to be fully charged to function. However, frequent insufficient charging over a period of weeks does result in reduction of the performance capacity.
  • Completely discharging the batteries insures extremely efficient utilization. If this does not occur regularly, the charging capability can be impaired.
  • Do not expose the battery charger to moisture. Store the batteries in a dry environment at room temperature.
  • A Lithium-Ion battery cannot be overcharged via the charging control in the battery pack. It can easily withstand an overnight stay in the socket, although it only needs 3 hours to fully load.
