Worked Great!

Date:October 1, 2012
"I got this charger when it was on sale, totally worth the money. My motorcycle battery was completely discharged and this charger easily fixed the issue.
The kit also comes with a hookup adapter than can be left on the battery to make it easier to charge without using the alligator clips."

CTEK Multi-use 3300 3.3A Battery Charger

Date:September 14, 2012
"Best charger I have ever bought. This little charger is the best to maintain almost any battery to a full charging state while preventing unneeded overcharging wear like most chargers out there.
Basically if you store away for a few months any boat, car, motorcycle, and plane this is the charger for you."

Good, but not the best.

Date:August 3, 2012
"I have two of these and they work well. I also purchased CTek's latest version called the Multi-US 4.3. Great products and even better when they go on sale.
To add more functionality, you can order more accessories, such as the cigarette lighter adapter, so you can charge the car battery via the cigarette lighter (as long as the receptacle is on).
As for the best, there are more expensive chargers out there, but for the money, you cannot go wrong with the CTeks."

Great high-end charger

Date:April 24, 2012
"This is the same charger that high-end automakers such as Mercedes-Benz, Porsche, Lamborghini and Ferrari re-brand as their own charger and mark up 300%. Well worth the investment if you make short drives or store your vehicle over the winter."

I should have bought one long time ago

Date:April 1, 2012
"PRO's - tests and charges new, used and weak batteries. This little guy restored my truck battery from sulfation and saved me $230 from a new one. Excellent Trickle charger and maintainer for most of your lead acid battery needs.
CON: Not great if you need a faster charge. Go to a standard charger or CTEK7002 and up models. I wish Canadian Tire carried other CTEK models.
BTW: It does pulse charge you just have to wait for it. It does not have the same pulse charging system that others have."

Not as good as many think

Date:February 15, 2012
"I know from the reviews here that many think it is a great charger, unfortunately, how many actually have the facilites to perform tests in a lab.
I tested both CTEK Multi US 3300 chargers that I bought and neither of them go into Pulse Maintenance Mode which happens to be the last stage of the advertized 4-stage charger that it is supposed to be.
I contacted CTEK in the US and they weren't very forthcoming with info. I think I caught them with their pants down. Page 7 of the on-line manual states that the charger can "manually be placed into Pulse Maintenance Mode". CTEK told me that was a mistake in the manual, yet could not tell me why it wouldn't perform that mode.
To be honest, I doubt any of them go into Pulse Maintenance Mode.
Yes, it charges batteries, but I want what was advertized and paid for."

Best charger ever, unless you're in a rush.

Date:February 5, 2012
"Easy to use, sturdy, not too poweful (a good thing). The CFT clerk told me that the only downside of this charger is that it does not charge a completely flat battery fast enough. I don't have to charge my batteries in 5 minutes, if I'm in a rush I use a battery pack. I don't plan to charge the batteries of the space shuttle anytime soon anyway. Best charger you can get for your car or motorcycle batteries, especially at 40 percent off."

The best 3.3 Amp charger/maintainer

Date:February 3, 2012
"I tested this charger against a less expensive 1.5 Amp Schumacher charger/maintainer purchased from Walmart. The Schumacher emitted off gases likened to what you would smell when hard plastic is warmed to around 35 degrees Celsius. The CTEK reached the same temperature odour free. Plus, at 3.3 Amps, the CTEK charged a 12 Volt 20 Amp-Hour battery quicker than the 1.5 Amp Schumacher. This charger is definitely worth purchasing especially when it is discounted 40% to $49.99."

Great for storing your toys in the winter

Date:January 1, 2012
"This charger actually performs as it claims.
Most chargers that claim to be compatible with AGM batteries actually put out too much voltage and will damage the battery if left hooked up too long. The CTEK 3300 on motorcycle mode does a great job either as a trickle charger or for topping up you lawnmower, snowmobile, ATV, boat, etc... batteries in the off season without fear of damage or boiling the battery dry.
The optional quick connect harnesses mean that for all the toys, you get a simple plug and play connection without having to remove the battery or risk shorting the alligator clips to the frame."

Works for the boss' Mercedes...

Date:November 4, 2011
"I bought this CTEK 3300 on the advice of my boss who has used it for three winters to keep the charge on his winter-stored Mercedes convertible. He also has one on his array of 6V RV batteries, which is what I use mine for.
Tried the Motomaster one last year, it was okay but had some minor annoyances/issues. This CTEK unit kills the MM one. After two months of having the batteries hooked up, I tested them out with several 6V and 12V applications - they were fully charged and performed beautifully. I feel confident that my expensive 6V deep cycle RV batteries will be ready come next spring."

very well designed

Date:June 9, 2011
"I bought this battery maintainer three years ago and it keeps my battery fully charged. I like the idea it will not over charge my battery. The lights on top will tell you if it is charging or maintaining the battery. A little expensive but good deal if you buy it on sale. Don't make the mistake and buy a cheaper brand it won't compare."

One of the Best Chargers for Motorcycle Batteries

Date:May 5, 2011
"I purchased this item as a result of a referral by a friend of mine. It was purchased to tender my motorcycle battery during the winter months. I bought this item when it went on sale ($49.99). I used it this past winter and it was the easiest thing to use. It kept the battery charged and it is nice and compact. If you are a owner of a motorcycle or small vehicle that uses a battery, I would highly recommend getting this charger. You won't regret it."

If you store your toy - a must have.

Date:January 1, 2010
"Used the CTEK #3300 for the last two winters to keep the battery charged on winter stored Mercedes-Benz E320. Easy to hook up with the equipment provided, and the most important thing when it's time to turn the key .. the car starts. Going to get a second one for my winter stored convertable. Great product."

Awesome Charger!

Date:January 1, 2010
"This is the best charger that I've ever owned. It not only charges all batteries, it is safe to use all the time to keep a battery at full charged. I leave it hooked up for months on my Sunday ride and it doesn't cook the battery. It has a pulse mode that senses when the charge level dips and only comes on at that time (remains off/dormant otherwise). I highly recommend this charger."

Don't waste your money on anything else!

Date:June 17, 2009
"This charger is truly capable of doing what it claims. I just revived a battery for my neighbor that his brand new motormaster computer controlled unit could not. Don't let its size fool you, the technology inside is amazing. It can also do motorcycle batteries."
