CTEK 3300 - Excellent Charger
The CTEK 3300 is used on a collectible car to maintain the battery and it works great. I've also used it on motorcycles, lawn tractors with good success. It is very easy to understand and use. I would recommend it for similar use.

Awesome product to keep my extra cars action ready. A similar product from Merecedes Benz costs twice as much. This one has more features and costs less.

CKEK 3300 Charger
I have over 10 of these units for all my cars. Half the price of the same unit with a car companies name on it. This is the exact same units as the one that came with my Porsche.
I received very fast delivery and will order more as needed from this company.
Thanks for the excellent service.

The best charger available. I have two of these and leave them connected to classic cars for months at a time so the batteries are always ready to go.
