Maximizing battery life

Avoid extreme ambient temperatures

Your device is designed to perform well in a wide range of ambient temperatures, with 62° to 72° F (16° to 22° C) as the ideal comfort zone. It’s especially important to avoid exposing your device to ambient temperatures higher than 95° F (35° C), which can permanently damage battery capacity.

Store it half-charged when storing long term

If you want to store your device long term (e.g. summer breaks), two key factors will affect the overall health of your battery: the environmental temperature and the percentage of charge on the battery when it’s powered down for storage. Therefore, we recommend the following: 

  • Do not fully charge or discharge the battery – charge to around 50%.
  • Power down the device.
  • Store in a cool moist-free environment less than 90° F (32° C).
  • Top up charge to 50-70% every 3 months.

During regular use

Do not run battery completely flat and do not leave product connected to charger when fully charged.
