CTEK XS7000 Battery Charger

Universal charger for cars, boats, and RVs.

The MULTI XS 7000 is suited for cars, boats, and RVs. This charger is ideal for year-round use. The supply mode provides you with power even without a battery. It also works as a Memory saver so you can unhook the battery without loosing settings and codes in vehicle computers, ant-theft radios, keyless-entry systems, etc. The Boost mode reconditions your battery after deep discharging. Your battery will recover quickly and last longer.

Uses for Charger

RV's
The MULTI XS 7000 provides more power and can also be used in the absence of batteries.
Cars and tractors
The MULTI XS 7000 provides more power and its supply function can also simplify battery replacement..
Heavy vehicles
An alternative is to the MULTI XS 14000 is to use one MULTI XS 7000 for each 12 Volt battery. The individual treatment of each battery prolongs battery life.
Boats
The MULTI XS 7000 is ideal for leisure batteries.

Batteries

The MULTI XS 7000 can be set very easily to charge different types of lead-acid batteries (Wet, MF, GEL and AGM) and conditions. You will find an explanation of the various battery types under Charger University, Battery Types.

The MULTI XS 7000 charges a wide range of battery sizes, from 14Ah to 225Ah.

Safety

• Electronic safe, the charger will not damage vehicle electronics. The battery does not normally need to be disconnected from the vehicle when charging.
• Minimal gas build-up and a patent-pending spark protection system. (however, in supply mode the spark free feature is disconnected).
• Short circuit and reverse polarity protected.
• Double insulation.
• Splash and dust proof (IP65) and approved for outdoor use.
• Progressive temperature protection.

Charging

The MULTI XS 7000 has a fully automatic, eight step charge:
1. Desulphation
Desulphation with pulsing for sulphated batteries.
2. Start
Starting phase for charging. The starting phase continues until the battery's terminal voltage has risen over a preset level. At this point, charging goes into the bulk phase. If the terminal voltage has not reached the preset level within a preset time, charging is suspended. The error mode is indicated. This indicates a battery which is faulty or has too large capacity. If a large battery is charged that has been severely discharged, it may be necessary to restart the charger after a preset time.
3. Bulk
Primary charging where approximately 80% of the charging takes place. The charger delivers maximum current until the terminal voltage has risen to the preset level. After a number of hours, the charger goes on to the next phase, even if maximum voltage is not reached.
4. Absorption
Final charging, voltage is kept at the preset level. During this phase, the current is gradually reduced. If the maximum length of time for Absorption is exceeded, the charger automatically continues with Analysis.
5. Analysis
Charging is suspended for a short period and the battery voltage measured. If it falls too quickly, the battery is probably faulty. Charging is suspended and an error is indicated.
6. Recond
Recond is used to recover severely discharged flooded batteries and for reconditioning severely discharged batteries suffering from stratification. The voltage increases with reduced current for a limited time period (depending on the charge level of the battery at start). The higher voltage starts some gassing and mixing of the acid, which is beneficial for both battery capacity and expected life. The battery could emit explosive gas during this step.
7. Maintenance charging - float
During the first 10 days of maintenance charging the battery is maintained with constant voltage.
8. Maintenance charging - pulse
State of charge varies between 95% and 100%. The battery receives a pulse when the voltage sinks, keeping the battery in good shape when it is not being used. The charger can be connected for months at a time. If the battery is charged and/or the battery's terminal voltage drops, the charger starts a charge pulse until the voltage has reached the preset level. The charge pulse is then interrupted and the cycle is repeated as long as the charger is in pulse maintenance phase. If the terminal voltage drops even lower, the charger automatically reverts to the beginning of the charging curve. If possible, check the water level in the battery.

Using the MULTI XS 7000 gives your battery an optimum service life and operational reliability.

*) Back current drain is what drains the battery if the charger is connected without the power cord connected.

**) Ripple denotes the amount of interference there is to 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. Voltage ripple could harm other equipment, which is connected to the battery. The MULTI XS 7000 delivers voltage and current with very low ripple. The battery gains a long service life and there is no risk of damage to other electronic devices connected to the battery.
