Product details

The internal battery remains fully charged for up to a year. The CS Free features revolutionary Adaptive Boost technology, allowing you to quickly get started even with a deeply discharged battery. The CS Free automatically analyzes the condition of your battery and adjusts to its voltage level. It then calculates the safest and fastest way to provide your battery with the energy it needs to start your vehicle within 15 minutes. The CS Free works anywhere and can also be operated with the optionally available solar panel kit or a 12V service battery for long-term maintenance charging.
