OUR MOST UNIVERSAL, UNIQUE, AND TECHNOLOGICALLY ADVANCED SMARTER CHARGER

The MULTI US 7002 (Part No. 56-353) is the ideal battery charger for your camper, 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 cars, boats with one battery, boats with start & service batteries, boats with start & service banks, scooters, motorcycles, Quads/ATVs, lawnmowers, RVs, and tractors (min 14Ah battery).

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 newly 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 switch 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.

What is AGM?

AGM stands for Absorbed Glass Mat and differs from a standard Flooded battery in that the electrolyte is held on a fibre glass mat and pressed against the active plate area, instead of being allowed to flood around the plates. This type of battery has a low internal resistance and can accept charge very quickly making it ideal for the modern start stop systems. If the battery casing should become damaged the electrolyte will not leak out.


What is EFB or ECM?

EFB stands for Enhanced Flooded Battery, ECM stands for enhanced cyclic mat, two different names for the same type of battery and both are similar in set up to a standard Flooded battery. There are some design changes with this technology, active plate material is more dense, anti-corrosion treatment for negative and positive grid and lower specific gravity to improve charge acceptance are just some of the differences. The EFB battery provides a more cost-effective battery solution over more expensive AGM type batteries.


What is CA/CA?

Calcium/Calcium batteries are a flooded low maintenance or maintenance free battery usually VRLA type. During construction some of the Antimony used in the construction is replaced by Calcium (2% approx.). The benefits are a more robust grid, low water loss and longer shelf life.


What is WET/ FLOODED?

The Flooded battery consists of a series of negative plates (sponge lead) and positive plates (Lead Dioxide) separator material and an Electrolyte solution which is approx. 65% water 35% Sulphuric acid. The flooded type of battery can be vented (which can be topped up) or VRLA which is sealed.

 

What is MF/VRLA?

MF or Maintenance free also known as a VRLA or Valve Regulated Battery type battery is a flooded battery with the addition of Calcium / Silver to the grid material to reduce gassing and water loss. The battery becomes a small pressure vessel by the addition of a pressure valve (instead of the vents in a standard battery) designed to retain gasses created during charging process - Hydrogen and Oxygen within the battery long enough to recombine into water, which replenishes the electrolyte level. Because of this process these batteries are also called recombination batteries.


What is GEL?

The Gel battery differs from any other lead acid battery because the electrolyte is no longer a fluid, Silica is added to create an electrolyte Gel which is applied to the active surface area of the plate. If the battery casing should become damaged the electrolyte will not leak out.


What is SPIRAL CELL?

A very distinctive looking battery, and very similar internally to the AGM battery. But instead of the plates being flat they are wound together very tightly into a cylindrical shape, which gives the battery its name Spiral cell. If the battery casing should become damaged the electrolyte will not leak out.


What is LiFePo4?

The lithium iron phosphate (LiFePO4) battery is a totally different technology from all the lead acid types mentioned previously. Due to its low weight and high-power output, it has become very popular in weight critical environments such as Powersports etc. The replacement cost of the unit at present makes its application restricted


What does SoC mean?

SoC means State of Charge and gives the state of charge as a percentage. A battery that has 11.65V (or less) is flat and has SoC 0. A battery with 12.76V (or more) is fully charged and has SoC 100.


Can you charge a lead acid battery with the Lithium mode?

No - CTEK recommend the correct charge mode be used at all times.
