Ctek Mxs 7.0 8 Step Battery Charger (7 Amp)

The universal battery charger.

The MULTI XS 7000 is an ideal battery charger for your caravan, car and boat. The battery charger is well suited for year-round use. Thanks to its SUPPLY mode the battery charger provides power even without a battery. The SUPPLY mode is indispensable when changing the battery as you avoid losing complicated program settings. Using RECOND mode, you can correct the acid stratification that often occurs in deeply discharged batteries. The battery thereby has its power restored and has a longer service life.

The MULTI XS 7000 is an ideal battery charger for your caravan, car and boat. The battery charger is well suited for year-round use. Thanks to its SUPPLY mode the battery charger provides power even without a battery. The SUPPLY mode is indispensable when changing the battery as you avoid losing complicated program settings. Using RECOND mode, you can correct the acid stratification that often occurs in deeply discharged batteries. The battery thereby has its power restored and has a longer service life.

Charging:
The MULTI XS 7000 has a fully automatic, eight step charge:

Setting: 14.4V or 14.7V

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.
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.
Bulk
Charging where 80% of the energy is returned. The charger delivers maximum current until the battery voltage has reached the set level.
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.
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.
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.
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.

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.

SETTINGS EXPLANATION:
14.4V Normal setting for wet batteries, MF and for most Gel batteries.
14.7V This setting is recommended for charging batteries at temperatures lower than -5 degrees C. It is also suitable for many AGM batteries.
13.6V/SUPPLY In this mode, the charger delivers a constant voltage of 13.6V. This is the best maintenance mode for applications where maximum capacity from the battery is important. The MULTI XS 7000 can also be used as a power supply without a battery attached in this mode. No counter voltage is necessary to start the charger in this mode. Note that the spark free function is suppressed in this mode, the reverse polarity protection works but there is no indication.
16V/RECOND This mode is used to recover severely discharged batteries where you might expect stratified acid (high acid weight at the bottom, low on top). Note that the battery has to be fully charged first. Use this mode with care, as the high voltage may cause some water loss. 16V is normally no problem for electronics in 12V systems, although maximum effect and minimum risk for electronics is achieved by disconnecting the battery.

*) 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.

Mounting:
The charger is easily fitted in place using two screws. The diameter of the mounting holes is 4.5mm located as shown in the image. The image also shows the dimensions of the charger.
