CTEK Power’s Multi US 7002 is a primary switch mode battery charger with pulse maintenance, representing state-of-the-art technology for battery charging. The Multi US 7002 features multiple charging modes, as well as a unique 8-step charging curve. Taken together these refined and new technologies allow the Multi US 7002 to move far beyond the capabilities of other 12V chargers, even to the point of determining whether a battery can hold the charge given, and in the process ensure that each of your lead-acid vehicle batteries gets the best possible care.

Eight-step Automatic Battery Charging Cycle
Going forward, there is no need for any specific knowledge of batteries or their charging methods; CTEK’s 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. These include: desulphation, allowing for possible reconditioning of batteries that have lost power due nonuse.; Soft Start, which charges until the battery’s terminal voltage has risen to a preset level; Bulk, in which primary charging to approximately 80% occurs; Absorption, a final charging stage where voltage is kept at a preset level; Analysis, during which charging a suspended and voltage measured; Recondition, where the battery is fed a constant current of 1.5A and maximum voltage of 15.7V; Float, during which constant voltage is maintained; and finally Pulse/Maintenance Charging, in which the battery receives a pulse of electricity when the voltage drops below 95%, keeping the battery in perfect condition indefinitely when it is not used. The Multi US 7002 is also perfectly suited for Optima Yellow Top batteries and can also be connected for months, which is ideal for seasonal vehicles.

Multiple Modes for Flexible Use
The Multi US 7002 is specifically developed for different needs, vehicles and batteries. With this in mind users can choose between several different modes. These include: Normal, for wet, maintenance-free and most Gel batteries; Cold Weather mode, recommended for use in conditions <41°F; Supply Mode, a maintenance mode supplying a constant voltage of 13.6V; and Recond Mode, a unique mode used to recondition batteries that have been severely discharged.
Charging for All-weather Conditions
A very light and compact charger, but still extremely robust and water and dust resistant (IP65 classification), the Multi US 7002 is designed to charge and maintain batteries, no matter the weather, temperature or situation. 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 and Compatibility
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.
Key Features:
- Eight step, automatic switch charging, with patented desulfation functionality to recondition batteries that have lost power due to non use.
- Charges 12-volt lead-acid batteries (Wet, MF, Gel, AGM and Ca).
- Maintenance pulse charging increases battery life and gives superb performance.
- Multiple modes including: Normal, for wet, maintenance-free and most Gel batteries; Cold Weather mode; Supply Mode, a maintenance mode supplying a constant voltage of 13.6V; and Recond Mode, a unique mode used to recondition batteries that have been severely discharged.
- Low back current drain, low ripple and input voltage independent.
- Delivered with two interchangeable connection leads, one with clamps, and one with eyelet terminals.
- The charger can be connected for months, ideal for seasonal vehicles, and compact design with mounting holes allows for permanent assembly.
- 5 year limited warranty.

* 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. The 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. |
