I have used the Ctek 3300 for a two years and it works great. I use it for periodical maintenance charging which allows the battery to stay in a healthy state. This maintenance charging will prolong the life of a battery. To this date, I have had no battery issues with my 08 corvette.
The CTEK Multi US 7002 is the next generation of charger 7A charger with a
lot more functions for safer, quicker and simplified charging. That's the
short answer. The detailed answer is, that the main differences beteween the
7000 and 7002 are:
. Higher pulse frequence during desulfation, which speeds up
this process
. Built-in timer for Soft Start that alerts the user that the
battery isn't accepting charge
. A more advanced algorithm to detemine that the battery is
fully charged, that detects parallel load and aged batteries
better.
. A built-in Analyze step that checks if the battery to keep
the charge. This step will both detect aged batteries
and batteries with a shortened cell.
. The Recond step is integrated in the charge cycle instead of
being separate
. Maintenance charge is a combination of Float (for maximized
capacity) and Pulse (for maximized life) that is unique for
CTEK. 7000 has on Pulse.

Got mine it two days ago!!! Planning on extending the "eyelet connection" about 8 inches. That way I can run the connector to right behind the license plate, and just plug it in from there.
