1956-2024 CTEK 12 Volt Battery Charger Multi US 7002

The CTEK 12 Volt Battery Charger MULTI US 7002 is perfect for your new Corvette as well as your vintage Corvette, vintage cars, boats, motorcycle, Quad/ATV, lawnmower, or tractor. Our Most Universal, Unique & Technologically Advanced Smarter Charger!

In addition, 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 in the vehicle.

Perfect for vintage cars, boats with one battery, boats with start & service batteries, boats with a start & service bank, scooters, motorcycles, Quads/ATVs lawnmowers, RVs, and tractors.

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

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 specifically designed to not damage electronic systems.

Designed for safety
All CTEK models are designed to protect the safety of the user. They are spark free, making the connection much easier and safer due to the gases that 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.
