Question for Ray (and others). You seem to be the electrical expert on this forum, so I was surprised that I couldn't find your opinion on these little CTEK battery chargers. I've heard good reviews on them, from this forum and others. I'm thinking of buying one, and I'm curious what you think of them? Do you have any experience with them?

I realize it's only a 3.3 amp charger, but it should be nice to maintain a charge over a long period of inactivity. Quick connect/disconnect too, with a permanent charge indicator.

I'm not Ray but I keep one on the winch battery in our race trailer all the time. I've had it for three years and works very well. You are right, they always have had great reviews...good product. We'll see what Ray says about them.

I have three of the small 3 amps and one bigger 7 amp. They are all good. The bigger one can wake up a dead optima, something I have not experienced with other "small" chargers.

Geeez, dont put any pressure on me, LOL. I am a little confused, as I think I know where these originated, but under a different name. Since they are patented, I am thinking maybe one in the same. If so, worth every dollar they are selling for. But personally I have never used a CTEK model. I would not use them for an inbetween rounds charger, but for maintenace, they are a great idea. The desulfation function is something not found on many of the smaller maintenance chargers.

I dont know that anyone would require a big amp unit. Most batteries need less than 1 amp for maintenance. So my pick would be the 3amp unit.

Yep, that's exactly what I'd use it for. Thanks for your expertise.

I've brought three back from the dead so far and my battery I use for racing is 12 years old so hey it has to work somewhat right?

Which one do I need for a Optima?

I've been selling them for over 3 years now and have never had an issue. Pretty awesome track record for anything eletronic, imo.

I know this is an older thread but I'm in the market for a charger and ran across these at Menards the other day. http://www.geniuschargers.com/G3500
Looks comparable, just don't know anyone who's used one for a review.
Right around $70.00 with tax.

I would think it is ok, it does mention the desulfaction process, which is what makes them different.

I recently purchased a CTEK Multi US 7002 (7A max, fully automatic - $100) and I love it. It also has the desulphation function. I like the convenience of the plug-in CTEK connector (I don't like alligator clips) and the Comfort Indicator (LED battery meter). Works great.

I ended up buying this same unit after I looked into it. I've brought back an optima, 2 autozone batteries and the one in my zero turn. This things is awesome!
