I bought a trickle charger which I am sharing with my son in law. We bought the CTEC as others advised. I used it for the first time over the weekend as the car has not had much use lately due to the weather and I wanted to try it out. After 7 hours it was showing the green light so I discontented it. The next day when I went out I noticed my hybrid battery was down too 2 bars, which is much lower than normal driving.
Any thoughts?
