Recommended Charging Practices for Performance Tool Jump Starter
Published 01/04/2017
Question:
I can see carrying this in my truck, especially during the winter months. My trucks 12v power adapter is always on, even with the key out. Id like to be able to keep this plugged in at all times, so that its always at 100 and ready when needed. If I turn the booster off, will that prevent it from discharging my vehicles primary battery when my truck is parked not running? Another scenario: If my vehicle battery dies, and the booster is left on, I can see that my vehicle battery would discharge and then pull the energy out of the booster through the charging circuit. Can I be sure that if I turn the booster off, that this scenario wont happen?

I checked with Performance Tool and they strongly advise not to keep the Jump Starter # PTW16751 plugged in 100 perecent of the time. The constant charging will overload the battery and damage the unit itself. It's a Lithium battery which should not be over charged, and most 12 volt chargers do not stop charging when a battery is full.
The battery is an 11,100 Mah battery and has a shelf life up to 3 to 6 months. It's recommended to fully charge the starter every 3 months since it needs to be at at least 50 percent charge to operate correctly.
