CTEK XS4003 Battery Charger

Practical household charger

The MULTI XS 4003 is a multitasker in compact format. It replaces all the chargers in your home. Switch between charging your lawn mower, the battery for your car or RV. The built in cold weather mode is perfect for flat batteries in the winter. The MULTI XS 4003 can even charge Gel and AGM batteries, where conventional transformer chargers cannot be used.

• Charges lead-acid batteries (Wet, MF, GEL and AGM) from 1.2Ah to 120Ah.
• Maintenance pulse charging increases battery life and gives superb performance.
• Charges even drained batteries.
• Pulse recover of slightly sulphated batteries.
• Three unique charging modes for use on small batteries, large batteries and a special cold mode that is also suitable for AGM batteries.
• Low back current drain, low ripple and input voltage independent (170-260V).
• High efficiency: 85%
• 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.
• Compact design with mounting holes for permanent assembly.
• 5 year warranty.

Batteries

The MULTI XS 4003 can be set very easily to charge Wet, MF, GEL and AGM lead-acid batteries. You will find an explanation of the various battery types under Charger University, Battery Types. You can use the MULTI XS 4003 to charge a range of batteries, from small 1.2Ah to large 120Ah.

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.
• 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 4003 has a fully automatic, four step charge:
1. Desulphation
Desulphation with pulsing for sulphated batteries.
2. 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.
3. 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.
4. 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 4003 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. The MULTI XS 4003's extremely low back current drain corresponds to 1Ah per month. Many other chargers have 1Ah per day.

**) 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 4003's ripple is only 2%. The battery gains a long service life and there is no risk of damage to other electronic devices connected to the battery.
