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, usin
