    Thanks for that test I was sceptical of the ctek as a desulfator. You have shown it doesn't really desulfate long and goes to auto charge you saved me getting one, I'm after a stand alone strong pulsing desulfator. Ctek here is a battery charger not much else cheers

      The 8A charger I reviewed last week as strong desulphation pulses and is a good strong charger to get the charge in quickly but use it for maintenance as the voltage cut off points are inaccurate..

    I would like the charger to pulse all the way during the charge cycle. If the battery is sulphated, it will take significant time to desulphate it properly. I wonder if it can be made to do that, over several weeks.

    • @razenby
      @razenby  4 года назад +1

      Longer would be better. It does dissolve the lead from the plates as it is effectively overcharging battery. Could lead to electrolyte loss if less too long.

    Great review and test of Ctek battery chargers. I'd like to see you test PulseTech Battery Charger's and PowerPulse battery desulfators. I use a PulseTech Power Pulse battery desulfator that you leave on your battery at all times, PulseTech claims that it will extend the battery life up to three times, and uses a patented frequency rather then voltage spikes.

    • @razenby
      @razenby  2 года назад +1

      Compared to wet lead acid, the specified charge profile on an AGM requires the maintain bulk charge to a higher terminal voltage and the charge terminates at a slightly higher voltage. Harder for longer and terminate the charge at a higher voltage. In practice the CTEK's A to D doesn't have the resolution or repeatable accuracy to do it correctly. It is an expensive piece of very cheap design.

  • @duncho1

    Is 30ms higher voltage pulsing present also at RECON mode (6) or in there it is just a constant 15.8V with limited current flow to 1.5A?

    • @razenby
      @razenby  3 года назад

      It depends on the internal resistance of the battery. There is no background charge happening only current caused by the pulse. Have a look at the latest NOCO genius 5 video.

      @@colinsvoboda7925 Personally, for a healthy battery I would not leave the CTEK not permanently connected. Also it does not have any temperature compensation. The CTEKs I have tested have the termination voltage set too high to prevent plate erosion. The MXS5.0 does not deal well with mains transients so leaving i connected 24/7 seems to be an issue.

      @@razenby The model I have MXS 5.0 (1090) North American model which claims to have charge voltage compensation according to ambient temperature although designed with a temp pickup within the case not sure the point unless it starts stone cold but even then the rise in internal temp would remove much benefit. It sounds like the NOCO handles maintenance and topping up better not to mention better build quality. Would you leave the Genuis connected to maintain or end up with the same result? Would be nice if NOCO included a lower amp setting but we can't have it all!

    What I don't understand is that CTEK charger goes in 1 second from step 1 to step 2, in 4 seconds to step 3, in another 5 seconds to step 4, but the pulses are shown in the oscilloscope for another 30 seconds. I would expect the charger to be in step 1 for that time (only the first LED on).

    My CTEK is hopeless on the Desulphation mode, it always just stay in the mode for a few seconds and it moves on to the next. The greatest success of this charger is the Swedish who can manage to convince people paying big money for a cheap and incapable charger.

    I have a CTEK MXS5.0 on stage 1 (desulph) for 3 full days now. For the first two days, it was a solid yellow, the third day is blinking every 2/3 seconds....it is working to desulphate? Its for a 2016 GX460 that was sitting unused for 4 months...

    • @razenby
      @razenby  2 года назад +4

      If the battery is too far gone it will never recover and the cycle wont ever end and all the lights wont come on. Unused for four months isn't a problem unless a vehicle has drained it below 11 volts at the terminals and it has been there for w while. In which case the battery is gone. say goodbye. For a disconnected battery most manufactures recommend a maintenance charge every six months and they also state that if the battery voltage measures below 11.5 volts the battery must not be sold but scrapped as it is 'irreversibly damaged'.

    The desulfation programme is there to remove Harmful sulphites from lead in the battery not charge it.

    • @razenby
      @razenby  3 года назад +2

      The CTEK desulphation mode overcharges the battery to erode the plates and hopefully remove sulfates by undermining their attachment to the plate. Hopefully without ruining the battery, On some chargers the repair mode includes a charge cycle and with others you are required to fully charge the battery before attempting a desulphation. On modem VRLA starting batteries it is a myth anyway,

  • @philalvirez4614
    @philalvirez4614 3 года назад +1

    desulfation shows 8 hrs: why that time? and what was the voltage at start of stage 1 and at the end? this way we could learn what improvement we get with desulfation and in what time. and tried the manufacturer but no response. they just want to sell...perhaps you know a better way to reach the right ones that could answer all my questions ?

    • @razenby
      @razenby  3 года назад

      Thanks for the comments. Refer to the NOCO Genius 5 playlist. The CTEK got sucked in by viewers and the detailed testing of CTEK VS NOCO recond modes on an ailing battery. Working OK on a daily basis but capacity was dropping. A series of 5 videos so far...

    My MXS 5.0 spends about three seconds on step 1 before going through 2 again, a couple of seconds and then onto 3. The battery is about five and a half years old. I did, out of curiousity, disconnect the -ve terminal and run the RECOND programme. It made no difference to anything but the car was behaving anyway.
    I think the desulf and RECOND modes are smokey mirror things. If the battery is that shot that this is necessary then it's time for a new one anyway. These programmes might get you a week or two's grace whilst organising getting a new battery fitted. That's all. It's a marketing thing.

    How does this ctek charger compare to the ultimate speed ulgd 5.0?

    • @razenby
      @razenby  4 года назад +1

      It is overpriced and overrated. The only + point over Climate Speed ULGD 5.0 is that the CTEK will recover a very flat battery because it doesn't have the 6V mode. In particular the termination of charge voltage was a long way out and the analyse stage is a scam on a timer. If you only need a 12v charger then DON'T buy an intelligent universal one that claims to do both 5 and 12V. They wont get you out f trouble if the 12V battery voltage goes too low.

      Didn't say it was however it is supposed to be intelligent and detect if reconditioning is needed. (See the patents). It spent quite a while in step 6 reconditioning (see chart). It made no difference to the Ah of the battery. I also tried a week in reconditioning mode and it made no difference to this battery. Smoke and mirrors and a row of LEDs works well for sales.
