This powerful, all-weather, 8-step charger uses a patented pulse-maintenance system to charge, maintain and help recondition 12V batteries. Includes a mode for small batteries. Sophisticated automatic charge cycle achieves the perfect charge.
This CTEK charger comes with two battery cables: one with clamp terminals and one with eyelet terminals. The 16" long eyelet-terminal cable can be left attached to the battery, and the clamp-terminal cable is great for temporary connections.
Whenever you want to charge the battery, just plug CTEK's patented Comfort Connect attachment terminal into the receiving end on either of the provided battery cables.
A goof-proof design distinguishes CTEK's new-generation chargers from the competition - you don't have to be a mechanical guru to keep your battery working at top efficiency. CTEK's patented charging system monitors your battery, providing exactly the charge it needs during each unique charging stage. Safe, eight-step process uses switch-mode, pulse-maintenance technology.
Your personal safety is paramount, and CTEK's spark-free, short-circuit-proof design incorporates a feature that prevents reverse polarity, keeping you safe. You simply cannot make a polarity mistake: The charger will not operate if it is attached incorrectly. In addition, the red alarm light on the charger alerts you if there is a reverse-polarity problem.
CTEK's patented switch-mode, pulse-maintenance charging system is designed with the most up-to-date technology to safely charge your battery. Using carefully monitored, low-grid voltage, CTEK's patented process differs from competitors' chargers by providing the precise final voltage that your battery needs to maintain the optimum charge level. This sophisticated, interactive device will never overcharge or undercharge your battery. You can leave it attached to the battery for months, making it perfect for seasonal vehicle storage.
Overcharging can cause gassing, which can lead to acid concentration and corrosion of the battery's lead plates. It can also cause the battery cells to dry out ("boil dry"), which can allow the battery to overheat and cause a fire.
Undercharging can be just as damaging to your battery as overcharging because chronic undercharging leads to sulfation. Sulfation occurs when the lead and lead dioxide of the battery's plates react with sulfuric battery acid to produce lead sulfate. This in turn is converted back to lead, lead oxide and sulfuric acid. A small, unavoidable amount of sulfation and gassing naturally takes place as a result of the chemical processes occurring in lead-acid batteries. However, extensive undercharging causes extra lead sulfate to accumulate on the lead plates of the battery. Because the crystalline form of the sulfate cannot hold an electrical charge, excessive sulfation greatly diminishes the charging ability of the battery, eventually rendering it unusable.
Desulfation is the reversal of sulfation damage. The CTEK charger's unique process not only prevents the undercharging that produces excess sulfation, but it also includes a desulfating step that can often "revive" a lightly sulfated battery. It accomplishes this with carefully monitored electronic pulses of energy that help to break down the lead sulfate crystals, allowing the battery to accept a charge once again.
Ripple-wave percentage is the quantity of disturbances exhibited in current and voltage. CTEK's low-ripple design regulates the incoming current before passing it on to your battery, ensuring a consistent charge. Unlike an old-style charger, this CTEK charger maintains precise control over the output current, keeping a battery healthier, more productive and longer lasting.
The charger is also safe for your vehicle. Its sophisticated circuitry is designed to be compatible with today's sensitive electronics and audio equipment. You can confidently charge your battery while it is still in the vehicle: no more hefting heavy batteries or dealing with tiresome system resetting! CTEK's low ripple rate eliminates the danger of damaging electronic devices connected to the battery, and it prolongs the battery's service life. Because the Recond (reconditioning) mode uses a higher voltage than other charging modes, using it may cause water loss in batteries and possibly shorten the life of your electronics. Check with vehicle manufacturer and battery supplier for information.

All right. Today we're going to review part number CTEK56864 from CTEK. This is a CTEK multi US 4.3 universal 12-volt battery charger with pulse maintenance and small-battery mode. A few things to know about this charger is that it comes with a variety of accessories. First off it comes with the familiar pair of clamps that go to the top of the battery to charge the battery. It also has a permanent install port that you can install to your battery.
That simply just bolts on to your existing battery post, and you get an easy plug-in whenever you need it. The charger itself has an easy-to-use connection point that will plug into whichever way you attach to your battery. When you're not using it it also comes with it's own storage bag. First we'll go ahead and show you how the charger will be used in a conventional way. First off we'll go ahead and take our clamps and attach it to our car battery. Then we'll take the battery charger and plug it into the port.
Lastly we go ahead and plug the charger into the wall. Then we need to select a mode, whether it's for a motorcycle, a car, a deep-cycle battery, or a reconditioning. Once we have the proper mode selected, then there's an indicator bar on top that shows you the progress of the battery charger. When the series of LEDs is all lit, the battery charger and maintenance is complete. Now for a car that gets stored for a long time and you want a permanent connection to the battery for the charger, you can use the CTEK comfort connect eyelet. These eyelets will connect directly to the battery. We'll go ahead and install it to this battery to give you and idea of how it looks and how it works.
In this case we're just going to use a couple extra nuts to go to the post on our battery. Now each battery's going to be different. There may be a need for extra accessories to connect to your battery. Once we get this permanently installed we can go ahead and use the charger to maintain the battery over long periods of time. Also when we need to use the vehicle, we'll take the port for a charger, put the cap back on, and then just tuck it out of the way, and we're ready to go.
Also for short periods of time you could use the CTEK comfort connect clamp to maintain the battery. Clamps just basically clamp on to your battery terminals. You can maintain your battery that way. Now this charger is designed not only for cars, but other vehicles as well, such as ATVs, UTVs, anthign that has a battery that gets stored for a long period of time can benefit from the use of the CTEK battery charger. For an example, we'll go ahead and use it on a UTV. Our UTV has already been equipped with a CTEK battery health indicator with panel box. This has part number CTEK56380. All we need to do is go ahead and take our CTEK charger and plug into the side. This UTV can sit for as long as it's needed, and the battery will be protected and charged. We're now finished for the review of the CTEK multi US 4.3 Universal 12-volt battery charger. .

Very high quality, compact, easy to use charger with many features. It is perfect for maintaining a charge on batteries that only get utilized periodically but can be used to charge as well. Would definitely recommend both the charger and etrailer.com. 132255
I bought two of these based on the recommendations of people on the Jet-Ski forum I'm on. I also found out that Porsche recommends this brand for their vehicles. I use them to maintain the charge in my intermittently used car and Jet-Ski so the chargers are used a lot. In one year of use I haven't had any battery or charger problems. The unit is capable of maintaining a charge and restoring a charge to a flat battery. It is hard to measure the performance of a charger but compared to previous chargers I have used I think it does a great job of keeping the battery functional. 274426

I have another trickle charger that I've used for years on my older Harley, but it is a single-mode charger. I decided to get a second one so I do not have to constantly move the one from the bike to the lawn mower to the car, etc and chose this one based on excellent reports from my co-workers who also use this C-TEK unit. Having had this in use for about 3 weeks now I can report that it works well, offers several modes, including the winter storage mode I am using now, and came with very detailed instructions and plenty of adapters for various applications. I'd buy this again. 114205
The reconditioning mode on the 4.3 did in fact recondition my car battery when simply charging it with a CTEK 3.3 didn't. I conclude this based on the better retention of charge after the 4.3 than after the 3.3. As always, etrailer's service was prompt and courteous when I ordered a second 4.3 DS 74922
After a recommendation from our mechanic, we purchased two CTEK trickle chargers and are extremely excited about how they will benefit the battery life of these cars over the next several years. All we can say now is, so far...so good. 151954
