12V | Dual input 20A charger with selectable output charge voltages The D250SE is a fully automatic, 5 step charger that supplies up to 20A of power to any 12V lead-acid or ­lithium* service battery from 40–300Ah.

The CTEK XS 0.8 Features:

* Six step, fully automatic switch mode model.
* Charges lead-acid batteries (Wet, MF, GEL and AGM) from 1.2Ah to 32Ah.
* Maintenance charging for batteries from 1.2Ah to 100Ah.

* Maintenance pulse charging increases battery life and gives superb performance.
* Charges even drained batteries up to 32AH.
* Pulse recover of slightly sulphated 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.

Charging - The XS 0.8 has a fully automatic, Six 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. Bulk
Charging where 80% of the energy is returned. The charger delivers a constant current until the battery voltage has reached the set level.

3. 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.

4. Analyse
via a short intermission in the charge cycle where the charger analyses the voltage drop and tests the self-discharge. The voltage of a defective battery will quickly drop. The charge cycle will be stopped with a warning indication if voltage drops to 12.6V in 2 minutes.

5. Float
Float is maintenance charge at constant voltage, keeping the batteries at 100% charge. In normal charging mode, float is time-limited (max 10 days) while supply mode goes on indefinitely.

6. 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.

Using the XS 800 gives your battery an optimum service life and operational reliability.
The XS 0.8 is easy to use. You do not need to make any settings. The charger adapts the charge to suit the battery and switches to pulse maintenance charging when the battery is fully charged.
