It is a common phenomenon for most of lithium-ion batteries to experience a dramatic power efficiency decrease caused by the freezing weather. Lithium batteries rely on chemical reactions to work, and the cold can slow down the reactions greatly.
However, our HULKMAN Alpha jump starter patented with the low-temperature resistant batteries can be stored and operated at a much lower temperature than the temperature other jump starters could be stored.
But, we still don't recommend storing the jump starter at an extremely low temperature for a long term, which outside the storage temperature range. It may cause an overall degradation of the battery.

Recommendations for storing your device in low temperature
- Avoid extreme temperatures
Despite your device has a wider storage & operating temperature range than most other jump starters, at extreme temperatures, however, your device has a efficiency reduction, which may contribute to an overall degradation.
- Keep the battery level above 80%
We recommend that you recharge your jump starter every 3 months to keep the battery power above
80%. It can prolong your battery lifespan and prevent emergencies from happening.
- Place your device in a warmer temperature environment before using it
If you store your device at a low temperature, we suggest you place it in a warmer environment before using it. Your device would have a better performance at room temperature.
However, you can omit this step if your device is Alpha 85S or Alpha 100, upgraded with the Pre-Heat Tech. Learn more about Pre-Heat Tech:Use the Pre-Heat Function to start your car at -40℉ temp.
