Product Description
The CTEK MULTI US 3300 is a versatile battery charger in a compact format that makes it convenient and easy to charge and maintain all household vehicles. The special cold mode means that you can charge during the extreme winter months without problem. It is perfect for everyday vehicles as wells as vintage vehicles, RV's, boats, motorcycles, ATV's, lawnmowers and tractors. This charger specifically developed for different needs, vehicles and batteries.
It is a fully automatic (connect and forget) 4 step charger. Once switched to the preferred mode, the charger takes its own readings and then begins to charge the battery. Once the battery is charged, it will automatically switch to its maintenance phase. The patented pulse charging process is arguably the most caring mode for a battery connected for a long time.
Unused batteries lose their power and their life is shortened through sulphation. It is more difficult to charge sulfated batteries. The US 3300 has a patented method for reconditioning sulfated batteries. The charger analyzes the state of the battery and , if possible, recovers the battery and its power.
All CTEK chargers are designed to consider the safety of the user. They are spark free, making the connection much easier and safer. They are also protected from reverse polarity connections and short circuit proof protecting the sensitive electronic systems in vehicles today. If the battery is connected backwards the charger will show a red light and not charge until it is properly connected to the battery.
The Multi US 3300 battery charger has a 5 year Limited warranty

I purchased this CTEK because it was specifically rated to charge AGM batteries and the durability reviews were good. Remember folks, THIS IS A TRICKLE CHARGER, really a battery maintainer that needs to be connected for at least a day (and preferably longer) to do its work. If you need to quickly bulk charge your battery, use something else.
I set the CTEK to the AGM mode and connected it to my fully charged but dying Optima. After a couple of days the battery was holding at 14.7 volts, per the specs. I wasn't able to start the vehicle for a couple of weeks after I took the charger off, so when I did crank it up I fully expected to have lost all the gain the charger had made 2 weeks before. Much to my surprise the truck cranked like a brand new battery was installed! This much improved performance has been sustained since and I'm delighted with the results. If I can get another year out of this Optima the CTEK will have paid for itself in its first use.
Pros
* It has a mode specifically for AGM batteries
* It can be attached for long term storage
* It's simple to set up and operate
* Frankly, it works great!
Con - Even though it's designed by a Swedish company, it's made in China :-(
Overall, this was a great purchase. Getting another year out of a single battery will pay for this unit.
This charger has several different modes, too. I just left it on the normal car mode. I wasn't sure if it needed the winter mode or not. My buddy storing his Ferrari has the same charger, and he said he's always just used the "car" mode.
I've ended up with four CTEK's.
Batteries are expensive, and after much research, I've found that CTEK is the one to get, to protect that investment. Other chargers can damage batteries if left on too long. See Jay Leno's videos explaining this.
CTEK (56-353) MULTI US 7002 12-Volt Battery ($117) of the four CTEK's that I own, this is my favorite, because it has all the features of the CTEK (56-353) MULTI US 7002, with more power capability.
The CTEK 56-864 Mus 4.3 12 Volt Fully Automatic ($60) is a nice alternative if lower cost is required. (see below)
CTEK 56-864 Mus 4.3 12 Volt Fully Automatic ($60) of the four CTEK's that I have, this is my favorite below $100. The "mode select" and multi-LED's are nice, and it indicates desulfer, and recondition modes.
CTEK (56-158) MULTI US 3300 12 Volt Fully Automatic 4 Step Battery Charger ($65) -
This one gave me "buyers remorse". For $5 less, I prefer the CTEK 56-864 Mus 4.3 mentioned above.
The fewer LED indicators on the 56-158 leave something to be desired for information, as compared to the other CTEK's models. It also does not have an LED to indicate "recondition" mode, but the manufacturers information says that it does it automatically.
CTEK (56-865) US 0.8 12 Volt Fully Automatic 6 Step Battery Charger ($45)
This one is a nice less expensive choice as a CTEK for "healthy trickle charging maintenance", but the lack of extra features would lead me to choose the CTEK 56-864 Mus 4.3 12 Volt Fully Automatic ($60), or the CTEK (56-353) MULTI US 7002 12-Volt Battery ($117) if I would only have one.
The CTEK (56-959) MUS 4.3 TEST&CHARGE 12 Volt Fully Automatic Charger and Tester ($87), would be a nice choice if you do not have other testing equipment, but I am handy with other equipment for "testing" so I'll probably never get this one.
Be careful to not be rough with the alligator clips, because the plastic is brittle and breaks easily. Once the plastic insulator breaks off, you then have an exposed metal clamp. Also, if you get one of the high power units, and also a low power unit, the leads are interchangeable, but the smaller unit will have a smaller in-line fuse that can "blow" if it is used with the higher power unit.
Original writeup> Very nice unit. Very well designed. Very healthy for batteries.
Avoid the cheaper "knockoffs" under other name-brands.
It has a very nice "recondition" mode to extend battery life.
Most other chargers can damage batteries if left connected for long period maintenance.
Jay Leno has published YouTube Videos explaining how other chargers were allowing batteries in his fleet to fail early, and he switched to CTEK.
It is not a heavy duty jump starter for a very dead battery.
Research the different CTEK models to see which one fits your needs.
I work with electricity / electronics, and CTEK's design makes good technological sense.
I've purchased 4 of their models for different size batteries, and I've given some as gifts to my Dad's fleet : ) . He is also very impressed.
You will be happy to know that you have treated yourself and your equipment to a very high-end product.

All in all, a very easy charger to use and is better than the "Battery Tender" or the "Genius".
