CTEK charging station and charger I installed about a 2 months ago. I installed the charging station in my trunk but had no need to charge it until today. The car had been sitting for a few days while I was away so I decided this was as good a time as any. Battery wasnt dead just in the red from sitting. Easiest trickle charge ever. The lights on the charging station blink to inform you of your battery level. quick plug and let sit.....
