I bought my CTEK back in 2007. My 01 had a drain that would kill a battery in 3 days. At the time I was underway a lot so I didn't have time to fix it although I had an idea of what it was. The CTEK managed to keep the battery charged even with that drain. The issue was an iPod adapter that never turned off. Once I got rid of it the drain went away.
Not everyone can pull the cable. Some of us have to keep everything hooked up so the drive cycle doesn't reset for smog.
