Can I use the jump starter for a frozen battery?

Answer:

Never attempt to jump start a frozen battery, as it could cause significant damage to the vehicle and even pose a threat to the people involved.

Note: Although the Alpha 85S/100 upgraded with Pre-Heat Tech allows you to start your car in -40℉, it’s not built for a frozen battery. You need to thaw the frozen battery before it can be jump started. It is also recommended to replace a battery that’s been frozen, rather than attempt to revive it and cause potential damage to people and/or property.
