CTEK Multi US 7002

Our most universal, unique and technologically advanced smarter charger

The MULTI US 7002 (Part No. 56-353) is the ideal battery charger for your caravan, car and boat. The battery charger is well suited for all-year use. Thanks to its SUPPLY mode the battery charger provides power even without a battery. The SUPPLY mode is indispensable when changing the battery as you avoid losing complicated program settings.

Perfect for vintage car, boats with one battery, boats with start & service battery, boats with start & service bank, scooter, motorcycle, Quad/ATV, lawnmower, caravan, and tractor.

Includes two interchangeable connection leads, one with clamps, and one with eyelet terminals. 

The Universal Charger

A NEW GENERATION of CTEK universal charger, the MULTI US 7002 has a unique 8-step charging curve. This new refined technology developed by CTEK ensures that the vehicle's battery gets the best possible care. It even analyzes if the battery can hold the charge given. If it cannot, the battery is faulty and needs to be replaced. The CTEK chargers are developed for safety: personal, vehicle and battery.

Fully automatic - for charging and maintenance

There is no need for any specific knowledge of batteries or their charging methods; the MULTI US 7002 will take care of that. Once you switched to the preferred mode, the charger takes its own readings and then begins to charge the battery in 8 steps, including pulse maintenance for best performance and service life (arguably the most caring mode for a battery connected for a long time - a CTEK patented system). It is also perfectly suited for Optima Yellow Top batteries. The MULTI US 7002 can also be connected for months, which is ideal for seasonal vehicles.

Patented desulphation function

Unused batteries lose their power and their life is shortened through sulphation. It is also more difficult to charge sulfated batteries. The MULTI US 7002 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.

Made for all weather conditions and situations

The MULTI US 7002 is prepared to charge and maintain, no matter the weather, temperature or situation. The MULTI US 7002 is extremely robust and water and dust resistant (IP65 classification). The MULTI US 7002 is certified for use between -4°F and +122°F. In order to make things easier and more convenient, the Comfort Connect (eyelet terminals) can be permanently connected to the vehicle's battery.

Compatible with other electronic equipment

Most vehicles today are equipped with sensitive electronic systems. Unlike less-sophisticated chargers, there is no need to disconnect the battery; the MULTI US 7002 is specially designed to not damage electronic systems.

Designed for safety

All CTEK models are designed to consider the safety of the user. They are spark free, making the connection much easier and safer considering the gases batteries normally produce. The MULTI US 7002 is also protected from reverse-polarity connections and is short-circuit proof. A red light on the charger will simply indicate that the charging cannot begin until the user has connected the charger correctly.

Unique Supply and Recond mode

The Supply mode serves as a power supply unit that can run 12V equipment up to 7A. When changing a battery, important settings will therefore not be lost. The unique Recond mode restores the power capacity in a stratified battery, prolonging its life. The stratifying process starts after just a few deep discharges of the battery.

*) Back current drain is what drains the battery if the charger is connected without the power cord connected.
**) Ripple describes the quality of the current and voltage. A high current ripple heats the battery and shortens its life. A linear charger has a current ripple of 70-400% which is much larger than the maximum 5% for a modern sealed battery. High voltage ripple could harm other equipment that is connected to the battery. MULTI US 7002 delivers voltage and current with very low ripple. The battery has a long service life and there is no risk of damage to other electronic devices connected to the battery.

Benefits of using a CTEK Charger:

#1 Maximizes Battery Life

CTEK Smarter Chargers maximize the life of your battery. Our patented desulphation function can extend the life of your current battery 2-3 times that of its normal life. With an annual growth rate of over 50% for the last six years, people around the world are finding CTEK chargers as a valuable investment to keep their vehicles, boats, motorcycles, and much more, in prime condition.

#2 High-Quality Engineering

CTEK Smarter Chargers are of the highest-quality engineering, but don’t take our word for it. CTEK is the preferred battery charger for some of the most prestigious engineering brands in the world: Porsche, Audi, Lamborghini, Bentley Motors, Scania AB, BMW, Rolls-Royce Motor Cars, Chevrolet (Corvette), Ferrari, Alfa Romeo S.p.A., Maybach-Motorenbau GmbH, Aston Martin, Arctic Cat, Yamaha Motor Company, Maserati, Mercedes, and more. Plus, they are available at an affordable cost.

#3 Monitors and Maintains Battery Performance

CTEK Smarter Chargers smartly maintain the battery in prime condition through a series of 4 to 8 steps in our unique charging process. Our chargers constantly monitor the battery to understand the battery condition and then act accordingly: disulphate, revive, charge, condition and maintains. CTEK Smarter Chargers also regulate the main voltage to protect sensitive and expensive electronic and audio equipment. They even have a backup power supply that allows you to charge vehicle batteries without losing your vehicles program settings.

#4 Saves Time, Money and the Environment

CTEK Smarter Chargers can help you save time, battery costs, towing costs, repair costs, and the environment through regular battery maintenance. Why? Battery Failure is often reported as the number one cause for breakdowns around the world and with modern verhicles complex and sensitive electronic equipment, this continues to be a big issue. As a result, motorists are unnecessarily paying for battery replacements, towing, and mechanic time, then throwing their existing batteries away! (and doing so regularly).

#5 Re-Conditions Old / Dead Batteries

CTEK Smarter Chargers recondition and help revive dead batteries. Our unique reconditioning step allows the battery to recover quickly and last longer.

#6 Affordable Investment

For the cost of a battery, a CTEK charger can keep all of your batteries in prime condition and offer you peace of mind for years to come.

#7 Sparkproof and Shockproof to prevent accidents

CTEK Smarter Chargers are safer to charge with because their spark-free, short-circuit-proof design incorporates a feature that prevents reverse polarity. In other words, the charger will know if you attach one end to the wrong battery post and will not operate if it is attached incorrectly. Conveniently, the red alarm light on the charger alerts you if it wasn’t attached correctly so that you can get it connected properly.

 #8 Reliable and nearly indestructible

CTEK Smarter Chargers are durable and can perform under extreme weather environments, with a temperature range of (-4°F to +122°F). They are shockproof, weatherproof, dustproof, and fully approved for outdoor use (IP44-IP65).

#9 Plug and Play - no need to disconnect the battery

Even though CTEK Smarter Chargers are sophisticated “under the hood”, they are easy to use. CTEK’s patented float/pulse charging allows ‘set and forget’ for months at a time without harming the battery. Motorists do not need to have a specific knowledge of batteries or their charging methods. With each Smarter Charger intended for unsupervised use, CTEK is foolproof to connect. There is no need to even disconnect the battery during use – it’s simply ‘plug and play’.

#10 Multi-Purpose

 CTEK’s range of Smarter Chargers suits all types of lead-acid batteries for vehicles of all sizes and types including cars, motorbikes, marine vessels, agricultural vehicles, motor homes, lawn mowers, and more.
