CTEK Multi US 7002 Car Battery Charger (56-353)




We price match!

The CTEK MULTI US 7002 is the ideal car battery charger! Perfect for all cars including vintage cars, boats with one battery, boats with start & service battery, boats with start & service bank, RVs, campers, scooters, motorcycles, Quad/ATVs, lawnmowers, and tractors.

Thanks to the 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.

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.

Battery Info:
AGM: The AGM lead-acid batteries are sealed, maintenance free and easy to charge. Many automakers and car owners are adopting the use of AGM batteries for the increased starting demand of modern cars with start/stop feature. These are ideal for higher electricity demand (such as those with larger engines), and are more resilient to being drained. These batteries are designed to perform better in all temperature ranges and are more durable than flooded batteries.
(Examples are: Optima batteries, and Odyssey batteries)
EFB: Your vehicle will only require an EFB (Enhanced Flooded Batteries) battery if it currently has one. For example, vehicles with Stop-Start technology may use one of these batteries. These batteries are meant to tolerate the constant stopping and starting without impacting the battery. While similar to the AGM, it has a longer cycle life. The EFB battery will withstand more cycles of charge and discharge than an AGM before it reaches the end of its useable life.
CA/CA: A calcium battery is a lead acid battery with a calcium component. The battery container is fully sealed and maintenance-free. Many modern vehicles use calcium batteries as they are less likely to be affected by extreme weather conditions and higher charge rates.
Wet: Also called Flooded or Conventional, the wet cell batteries are the most commonly used car battery on the market. Usually flooded batteries are not sealed. Flooded batteries hold very good rates of charge for the price, but require more work.
Gel: The gel-filled lead-acid batteries come with a Geld filled’ label on the battery. Delicate and needs caution when charging, however NOT commonly used in vehicles.
MF: A maintenance free battery is a sealed battery that is easily identifiable because they do not have filler caps. Most new cars come standard with maintenance free batteries.
(A battery can be one of the above types and MF)
