CTEK® 56-353 MULTI US 7002 12V Battery Charger

Catalog #: 97004.1011
CTEK® Part #: 56-353
The powerful universal battery charger.

The MULTI US 7002 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. Using RECOND mode, you can correct the acid stratification that often occurs in deeply discharged batteries. The battery thereby has its power restored and has a longer service life
  • 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 prefered 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 desulfation
function Unused batteries lose their power and their life is shortened through sulfation. 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.
  • 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.
  • 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.
  • 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.
  • 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.

*) 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.
