CTEK Assist for CS FREE
The CS FREE is stuck at ¼ light when charging
This could mean that the internal battery has gone into UVP (Under Voltage Protection). There’s various reasons to why this happens. The main reason why is that the CS FREE has been left unattended for too long.
It takes approximetely 60-120 minutes to charge a CS FREE from 0-100%.
