Can I charge a dead battery with a CTEK charger? Most CTEK charger require a minimum battery voltage of 2V. If the battery voltage is below 2V you will need one of our chargers with a” Supply mode” to accomplish this. The Supply Mode function is currently available on our Multi US 7002, Pro25 series as well as our MXS 25EC chargers in North America.

MC = 14.4V / 0.8A for batteries 1.2 -14 Ah CAR = 14.4V/ Charger output (e.g., MXS 5.0 is 4.3A) SNOWFLAKE/AGM (MXS 5.0) = 14.7V SUPPLY = 13.6V/ up to a max charger output (e.g., Multi US 7002 = 7A)

Use programs according to the battery size or type: MC = 14.4V / 0.8A charge mode for smaller batteries using a low amperage - 0.8A charge rate. CAR = 14.4V/ Charge mode using the full amperage rating of the charger e.g., MXS 5.0 would use 4.3A for charging SNOWFLAKE / AGM= 14.7V/ Charge mode using the higher voltage required by some manufacturers.

CTEK recommend getting the battery tested - it may need replacing. Try to charge another battery where possible to exclude charger fault. Check the user manual for details on light patterns. This could indicate a problem with the battery. CTEK recommend getting the battery tested - it may need replacing.

Can I leave the charger connected to the battery for a long time? Yes. CTEK chargers are designed to fully charge a battery and then automatically switch over to long term maintenance. Before leaving the charger unattended for a long time ensure that the battery is fully charged as indicated by the green LED.

There is no reason to disconnect or remove the battery from the vehicle – or open the battery caps – while charging with CTEK. CTEK chargers are spark proof reverse polarity protected and electronically safe.

I can't guarantee that I will be at home when the charger says it's finished. Should I disconnect it and continue charging when I come home? No, you don't have to monitor on the charger. It will automatically switch to maintenance mode and keep the battery fully charged until you return.

A CTEK charger is so small. How can it charge so quickly and efficiently, when compared with ordinary chargers? CTEK's chargers use the same type of technology that computers use to reduce dimensions, to increase power and to charge using a well-controlled and 'pure' current. Also, think how big mobile telephones were 15 years ago and how small they are today, and can even so do so much more.

How deeply discharged can a battery be and still be recharged by a CTEK charger? Most CTEK 12V chargers can charge up batteries 2V. Our 6V charger can charge from 3V, and our 24V chargers manage batteries from 4V. Chargers equipped with the "Supply" mode need no counter voltage, and therefore can charge up batteries from 0V.

15.8V. Most manufacturers consider everything to be fine as long is voltage is below 16V and CTEK is under that limit by a good margin, even during Recond. Note that the service life of some components is shortened by high voltage. A rule of thumb says that a light bulb's life span is halved by increasing voltage by 5%, but this is normally not any great danger.

Are there CTEK chargers for other battery types? CTEK also produces the CTEK LITHIUM US charger, which has an ideal charging programme for 4x LiFePO4 (lithium iron phosphate) with a nominal 12V terminal voltage.

CTEK has never supplied Y-cables because it is an unsafe solution. With a Y-cable, you connect the batteries of the two motorcycles. You could compare this to the starter cables you use to jump-start a car. If one battery is fully charged and the other is completely drained, there is an incredibly high current between the batteries.

Can I leave the charger connected to the battery for a long time? Yes! CTEK chargers are developed to fully charge a battery and then automatically switch over to long term maintenance. Before leaving the charger unattended for long time, ensure that the battery is fully charged, indicated by a green light.

No. Lithium batteries needs a different charge than lead/acid batteries. Due to severe risks if overcharging, we do not recommend using a CTEK charger that is developed for lead/acid batteries, for that purpose. Charging lead/acid batteries with a Lithium charger does not give the best result and cannot be recommended.

What is WET/ FLOODED? The Flooded battery consists of a series of negative plates (sponge lead) and positive plates (Lead Dioxide) separator material and an Electrolyte solution which is approx. 65% water 35% Sulphuric acid. The flooded type of battery can be vented (which can be topped up) or VRLA which is sealed.

Sulphation is the cause of 85% of battery failures under warranty and is caused by a lack of charge - low voltage in the battery. Every CTEK charger starts its charge cycle with a de sulphation phase - designed to break down the sulphates and restore battery performance if it is required.

In Absorption the voltage is now constant, and the current is reduced to take the battery from 80% to 100% with minimal gassing, the CTEK charger is constantly responding to the amount of current the battery is taking and reducing accordingly.
