Troubleshooting Guide | Manual

Additional DescriptionMore Details

Perfect Battery Charger for Vintage

CTEK offers a wide range of NEW GENERATION battery chargers. Unlike old battery chargers, CTEK chargers are designed with a focus on simplicity, safety and flexibility. The UC 800 is the ultimate charger choice for 6V vehicles. It is perfectly suited for vintage cars and motorcycles and other 6V vehicles up to 100Ah.

Flexible care for battery needs

All CTEK chargers are developed to take special care of the batteries in the vehicle and at the same time focus on the safety of the person and the vehicle. Depending on the weather conditions, usage and the type of battery dictate the care that the battery needs. CTEK chargers are developed to handle virtually all lead-acid batteries, weather conditions and vehicle types. The importance of battery charging is clear when the statistics show that 70% of all battery returns are due to poorly charged batteries. Save time, money and work by charging batteries with a CTEK charger.

Fully-automatic – for charging and maintenance

There is no need for any specific knowledge of batteries or their charging methods; the UC 800 will take care of it. The charger takes its own readings and then begins to charge the battery. Once it is finished charging, it will automatically switch to its maintenance phase – CTEK’s patented pulse charging – arguably the most caring mode for a battery connected for a long time. The UC 800 can be connected for months, which is especially important 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 UC 800 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 UC 800 is specially designed to not damage electronic systems.

Made for all weather conditions and situations

The UC 800 is prepared to charge and maintain, no matter the weather, temperature or situation. The UC 800 is very light and compact, but it is extremely robust and water and dust resistant (IP65 classification). The UC 800 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 UC 800 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. UC 800 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.

Additional DescriptionMore Details

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.

A powerful charger for 12V batteries that require rapid charging such as in garages, RV’s, boats and of course cars. Unlike old traditional battery chargers CTEK chargers are designed with focus on simplicity, safety and flexibility.

Fully automatic – for charging and maintenance

In addition to normal charging of batteries, they also have a fully automatic charging cycle through CTEK’s in-house patented system for maintenance charging. The batteries are kept at full capacity (float) over the first 10 days period. The chargers then switch to pulse maintenance, which is the optimal way of storing the batteries in the long-term and providing them with maximum service life.

Patented desulfation function

Unused batteries lose their power and their life is shortened through sulphation. It is also more difficult to charge sulfated batteries. CTEK MULTI US 25000 has a patented method for reconditioning sulfated batteries. The charger analyses the state of the battery and then, if possible, recovers the battery and its power.

Weather independent

The chargers are fitted with temperature sensors adapting the charging voltage to suit the battery temperature and handle effective charging no matter the climate, from 0 0 F to 1200 F. They are very robust and have an IP44 classification, approved for outdoor use.

Electronic protection

Most vehicles today are equipped with sensitive electronic systems. Unlike less-sophisticated chargers, there is no need to disconnect the battery as CTEK MULTI US 25000 is specially designed not damage the electronic systems.

Unique SUPPLY and RECOND mode

The SUPPLY mode serves as a power supply unit which can run 12V equipment up to 25A. When changing a battery important settings will therefore not be lost. The unique RECOND mode restores the power capacity in a stratified battery and therefore prolongs its life.

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. CTEK MULTI US 25000 is also protected from reverse polarity connections and is short-circuit proof.
