I think your C-Tek charger is faulty or being upset by your test equipment, I've been using an MXS 5 and MXS 10 for years and neither of them have ever missed out stages in the process. Step 8 should not kick in until it has been at stage 7 for a week.

Glad I bought the noco 5, all I need it to do is keep the battery charged up on my golf gtd mk7.5, it's a 70ah battery, not getting much use at the moment, seems to be working fine so far, mixed reviews all over Amazon and Facebook for both units, after watching your videos I feel confident I made the right purchase

so i have a deep psycho battery that has been in a trailer that my boss uses for catering. It’s an old battery and I got it taking a charge and got it from him for my boat. i have been charging it now for 6hrs and was going to use the repair mode will it help the battery or hurt the battery. it’s pretty much a dead battery

I own a CTEK MXS 5.0, it does not get HOT at 0.8A setting but I have yet tried the 4.3A for charging. Thanks for your advice, I think I'll go get a fan and a power surge protector to pamper this HOT Swedish baby before it gets fried.

Thumbs up. Great review and test of Ctek and Noco battery chargers. I'd like to see you test PulseTech Battery Charger's and PowerPulse passive 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 than use voltage spikes.

Thanks god bless

I'm really enjoying this series. I'm holding off buying a charger until all the results are in . After the "CTEK vs NOCO GENIUS 5" test I'd be really interested to see a "Noco GENIUS 5 vs NOCO GENIUS 2" showdown. I'd be really interested to see whether a longer charge time at lower amps results in extra amp hours. I remember there was some indication that this may be the case during one of the early test runs of the Noco Genius 5.

I see parts 4 & 5 of the video. Where can parts 1, 2, and 3 be found? I'd like to start from part 1 and watch all the parts in sequence. Thanks in advance!

Thanks for the efforts. What do you think the "repair" or "recon" mode of these chargers suppose to accomplish? desulfation of large crystals? The drop seems to suggest that they are making it worse. No?

I have the C-TEK 7002 charger, it has the Power Supply mode, it is very useful.

Extremely grateful for going through the trouble of doing various tests and analysis. I am about to buy a charger and was doing the research whether to go for Ctek or Noco. Have read quite a bit of Ctek going wrong whilst can't see many Noco going wrong.

Thanks for this comparison, looking forward to end result 👍

That was really interesting! The point about heat/reliability is interesting, anecdotally I have a CTEK Multi US 3300 from around 2008 that lasted until 2022 when I repaired it. It’s still going in 2024.

Good comparation!

Just a query on the noco when are they actually fully charged?

8 comes on and off because it discharges and recharges to keep the battery alive.

È meglio il Noco Genius 5 oppure Ctek MXS 5.0 ???

I was wondering yesterday what was that video about; I mean, the title and the content didn't match. My CTEK MX 5.0 doesn't run hot at all, maybe because of the winter temperatures in the garage, so I still have some hope that this overpriced peace of "Swedish meatballs engineering skill" will last a few years. Or should I preemptively send it to you for an upgrade? (well, there is a 5 year warranty on the piece, but I doubt in it).

Neither of my CTEK chargers get hot.
