CTEK Multi XS-7000 Battery Charger
Key Benefits & Features:
The Ctek Multi XS 7000 battery charger is ideal for leisure batteries.
The Multi XS 7000 is a smart and practical battery charger for all types of lead-acid batteries and can even be used on Gel and AGM batteries, where conventional transformer chargers are not suitable. The Multi XS 7000 can be connected for long periods of time in it's protective pulse maintenance mode, and is safe for use with all electronics, so you don't have to disconnect the battery from your boat.
The Multi XS 7000 is spark-free, short circuit-proof, and reverse polarity protected. It can charge drained and sulphated batteries. Even if the mains voltage is as low as 170 Volts.
Splash and dust proof (IP65) and approved for outdoor use.
Features
General
- Six step, fully automatic switch mode model.
- Charges lead-acid batteries (Wet, MF, GEL and AGM) from 14Ah to 225Ah.
- Supply mode for float maintenance for 100 % state of charge.
- Charges even drained batteries.
- Pulse recover of slightly sulphated batteries.
- Four options: 14.4V, 14.7V, 13.6V/Supply and 16V/Boost.
- Low back current drain, low ripple and input voltage independent (170-260V).
- High efficiency: 85%
- Delivered with connection lead with clamps.
- The charger can be connected for months, ideal for seasonal vehicles.
- Compact design with mounting holes for permanent assembly.
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.
- Tested and approved by Intertec SEMKO AB. S-marked and conforms to the following standards:
EN 60335-1, EN 60335-2-29, EN 61000-3-2, EN 61000-3-3, EN55014-1.
Charging Characteristics
- The Multi XS 7000 has a fully automatic, seven step charge:
1. Desulphation
Runs a complete charge cycle within a fraction of a second. The cycle repeats during the whole desulphation phase. Every cycle recovers some lead sulphate into useful material.
2. Start
Starting phase for charging. Charging with limited charging current. The starting phase is over when the voltage rises above 10.5V, at which time the charger switches to bulk charging.
3. Bulk
Charging where 80% of the energy is returned. The charger delivers a constant current until the battery voltage has reached the set level.
4. Absorption
Final part of the charge up to 100%. The battery voltage is kept constant at the set level, during which time the current drops gradually.
5. Pulse
Maintenance charging. The state of charge varies between 95% and 100%. A pulse is sent out to the battery if the voltage drops. This keeps the battery in trim when not in use. The charger can be connected for months at a time.
6. Setting: Supply
The supply mode setting supplies a constant voltage at 13.6V and current up to 7A. It could be used for maintenance charge using the float approach. This approach keeps the battery at 100% state of charge, but the constant small overcharge also increases water loss.
In this mode, the MULTI XS 7000 can also be used as a power-supply unit for operating equipment that requires 13.6V and a maximum of 7A. The spark free feature is disconnected in this setting.
7. Setting: Boost 16V/1.5A/4h
The Boost setting gives a constant current at 1.5A, maximised at 16V for four hours. It will automatically switch to 14.4V pulse setting after four hours.
This mode is used for batteries that have been severely discharged.
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.
Dimensions
The charger can be easily fitted in place using two screws. This diameter of the mounting holes is 4.5mm located as shown in the image above.
