Specs:
This CTEK charger comes w/ two battery cables: one w/ clamp terminals and one w/ eyelet terminals. The 16" 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.
Superior and safe, this eight-step process (plus Supply Mode) uses switch-mode, pulse-maintenance technology.
Supply mode - available only on this CTEK model - provides backup power to your vehicle while the battery is being changed. No more tiresome system resetting after battery changes.
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!
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 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.
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! CTEK's low ripple rate eliminates the danger of damaging electronic devices connected to the battery, and it prolongs the battery's service life. If you must replace your battery, the Supply Mode provides backup power to your vehicle's systems when you remove or replace the battery, sparing you the hassle of resetting your controls.
Indicator lights on the face of the charger light up to show the current charging stage.

With this items I am fully satisfied - thanks for follow up - any time again
Great design / features, easy to use.
Have ordered from etrailer in the past, fast shipping and battery charger seems to operate fine!
Good price, quickly delivered, well presented on the web site, placing the order was easy, good email communication. Overall very pleased.
Exactly what I needed to maintain several different size batteries at the same time.
I used this for my boat batteries.
Using this on battery back sump pump system. Customer service was very helpful when I had questions on which model to order for the application. Thank you.
So far it looks great. Easy to set up and use. I'm using it to charge two 6 volt batteries hooked up in series.
This product has performed as advertised. Instructions were fine. I use it on my Lawn Tractor over the winter months.
I have ordered products from etrailer for years and have never been disappointed in the products , price or promptness of delivery.
The Ctek charger is small, but very effective. I have a vehicle that I only drive once or twice a month. Now I don't have to worry about the battery being dead and having to have the computer reprogram after jumping it off. Works great. Thanks Etrailer!!
This CTEK charger got my large automotive battery up to full capacity in no time, and is maintaining it perfect through cold winter storage. As usual, prompt & well packaged delivery from etrailer!
Exactly what I needed etrailer had. Fast delivery everything I ordered was in great condition. Great service. Have ordered from etrailer several times, always on time and is exactly what was ordered.
