CTEK UC 800 Charging Process

Safe, four-step process uses switch-mode, pulse-maintenance technology.

  1. Desulfation stage is the initial charging phase. This stage uses electronic pulses to desulfate batteries by converting lead sulfate crystals back to usable sulfuric acid.
  2. Bulk stage is the main charging phase. This stage accounts for 80 percent of the charging process and uses a constant charge level.
  3. Absorption stage completes the charge (to virtually 100 percent) using diminishing current to prevent battery damage.
  4. Pulse-maintenance stage begins 18 hours after the battery is fully charged. In this stage the charger maintains the battery at the optimum charge level of 95 to 100 percent by recognizing any drop in voltage and sending a corresponding pulse of current to keep the battery properly charged. Pulse maintenance can be continued for months at a time.

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!

Protects the User

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.



Protects the Battery

CTEK's patented, switch-mode, pulse-maintenance charging system is scientifically engineered to safely charge your battery by employing the most up-to-date technology. Using carefully monitored, low-grid voltage, CTEK's patented process differs from competitors' chargers in its ability to provide the precise final voltage that your battery needs to maintain optimum charge level. This sophisticated, interactive device will never overcharge or undercharge your battery. You may leave it attached to the battery for months, making it perfect for seasonal vehicle storage.

Won't cause overcharging or overheating. These together can cause gassing and excessive acid concentration that shortens the life of the battery by corroding the lead plates. When overcharged, the battery cells become dried out. Electrolytes "boil dry," generating excessive heat that can cause a fire.

Won't cause undercharging or sulfation. 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 w/ 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.

Provides desulfation w/ a patented process. Desulfation is the reversal of sulfation damage. The CTEK charger's unique process not only prevents the undercharging that produces excess sulfation, it also includes a desulfating step that can often "revive" a lightly sulfated battery. It accomplishes this w/ carefully monitored electronic pulses of energy that help to break down the lead sulfate crystals, allowing the battery to accept charge once again.

Ensures consistent charging w/ low ripple-wave percentage rate. Ripple-wave percentage is the quantity of disturbances exhibited in current and voltage. Even minor variations in household current can cause undercharging or overcharging, but CTEK's low-ripple design regulates the incoming current before passing it on to your battery. This process can cause the charger to be a little slower than linear chargers but results in a healthier, more productive, longer-lasting battery.



Protects the Vehicle and Its Electronics

The charger is also safe for your vehicle. Its sophisticated circuitry is designed to be compatible w/ 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 w/ 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.

CTEK US 800 12-Volt Battery Charger Review

Video Transcript for CTEK US 800 12-Volt Battery Charger Review

Today we are going to review part number CTEK56213 from CTEK. What this is is a battery charger designed for smaller batteries such as on your motorcycle, ATV, snowmobile, lawn mower, and also it would be a great addition to your trailer break away kit. A small 12 volt battery with that would be a perfect companion. We will go ahead and review some of the components that come with the kit and the typical application afterwards. :29

The CTEK charger comes complete with two different attachments to go to your battery. The one shown here is a permanent install, if your battery has terminals on it you can actually bolt these rings onto and leave this on there all the time. The second half comes with a pair of regular clamps that you see on jumper cables and other chargers. So that is great for small batteries with just tabs on them that do not have a bolt on terminal. :55

Moving on to the main component will be the charger itself. As you can see it has one end that will plug into the other attachments that go to the battery. Then you have the body of the charger itself. It does plug in to any 1-10 outlet. One nice detail about this is that it comes with a bag to store everything in that you use. There is a clear side here for your other two pieces. It also has a strap on top to hang it from a hook. In this demo we are going to use a trailer break away kit. We are going to use it to charge. So if your trailer is sitting over the winter not being used, go ahead and open up the case, disconnect the wires, and pull out your battery. Now you do not have to worry about taking the battery inside to charge it, because the whole unit is weather proof so you can leave it in the garage. Our little break away battery has just little tabs on the end so we will go ahead and use the clamps to attach it to. 2:03

We will go ahead and attach that to our CTEK charger. These simply snap together. Go ahead and hook up our terminals. Of course, red to red and black to black. Sometimes these batteries get kind of dirty and dusty, you can not see what is going on and may not be color coded. What happens is, if you actually get it wrong, black to red and red to black, and plug it in it will actually tell you right off the bat that you have your polarity reversed. So we will go ahead and fix our leads. Nothing lit up so go ahead and plug it in to our 1-10 outlet power supply. All right, it turns itself on instantly and already shows us the condition of the battery. It is only partly charged so it is going to go through all four steps to recharge the battery. And when it is fully charged, it will tell you with the green light that it is good to go. And also, for batteries that use the 6 volt system, there is an identical version of this charger that is designed for 6 volt applications. And that one is part number CTEK56191. And with that that finishes our review of part number CTEK56213.
