Over the course of the winter my pride and joy is tucked up in the garage with the dehumidifier and temperature controlled garage, which is vitally important. To supplement the car’s cosy environment is the next most important thing, the trickle charge to the battery. Couple of reasons being it keeps the battery at an optimum level and prolongs the life of the battery. I use the CTEK mxs5 which has served me well for the last eight years 24/7 and I haven’t had any problems, until now. The wall mounted charger showed that all was good and the unit was on the maintenance cycle as expected when I popped into the garage to check up and have a day messing around in there.

A couple of months or so ago I went to the garage and noticed that the unit’s quick connection (which has a traffic light set of LEDs) was flashing red, this is a visual sign of low power in the car’s battery. I just put it down to a recent power cut during a storm which had messed up the maintenance charge process. I reset the charger and the process started up again, and I thought no more of it. I went back in a couple of weeks ago and all looked OK. Something told me to check the battery level, I got in the car turned the ignition on and the volt meter was showing just over 11 volts not the 12.5 volts that should have been available. Those that know these old cars are aware that there is an ‘Ammeter’ not a volt meter in the instrument cluster. I didn’t like the idea of a direct battery feed going to the dash, it didn’t tell you a great deal either as they either didn’t work or just in the middle of the gauge. Safety in mind I swapped out the Ammeter for a volt meter which I made on my own. (If you want to know how I swapped the stock Ammeter to a modern voltmeter that also still looks stock, click here.)

I tried to turn the car over which was rather slow, but eventually she fired up before what seemed like an eternity of ever slowing turn overs until I reckon the last but one revolution of the starter motor managed to fire the car into life.

I ran the car for a few minutes to get a little power charge into the battery while I finished up what I was doing in the garage. After shutting the car down and reconnecting the charger back up, I closed up the garage and wandered back into the house where I assumed the horizontal position on the sofa to start researching the issue. I found a forum where it seems there is a generic failure where these units show the maintenance cycle, but it’s not actually trickle charging the battery, so the battery runs low. I got into some heavy reading looking for the replacement, and to see if anything new was on the market since I bought that last one. I have previously given the CTEK unit 10 out of 10 and after (nearly) nine years it’s still a deserved score, and they still make them. With that in mind I was certain that I was going to do a like for like CTEK swap out, but another brand ‘NOCO’ caught my eye. I did the usual comparison, review readings and there was virtually nothing in it between the two manufacturers for the price and functions. So I ordered the NOCO for one reason only. I have also reviewed the NOCO Genius 5 here or cut and paste this link to read it:

NOCO Genius % battery charger (onemanandhismustang.com)

That one reason? Taken from the NOCO website;

“Thermal Comparison: the new integrated thermal sensor automatically monitors and adjusts the charging cycle based on fluctuations of ambient temperature, limiting the chance of under-charging or over-charging, providing a more accurate and fully charged battery. Avoids under-charging in cold weather down to -4F and avoids over-charging in hot weather up to 104F.”

My garage can get hot sometimes in the summer, so this ‘Thermal Comparison’ for me was the winning function, just pipping the CTEK. To replace the CTEX with the same model would have been literally five minutes, going to another supplier was something I knew would take a little bit of time to get it nice and neat under the hood, back to how I wanted it, out of sight out of mind.

The NOCO doesn’t look as fancy as the CTEK, but it’s function for me at the end of the day, I don’t have to look at it all the time, so it’s not really an issue or is it?

Once unpacked there is a rubbish bracket that clips to the NOCO and is held in place by a rather tacky looking velcro strap. You have to thread the strap under the unit into the bracket’s loop all of which is a bit cumbersome. Perhaps it’s a quick release, but it would have been nice to have a wall mount without the velcro. For £80 I would have wanted something a little nicer looking to be honest. When I walk into the garage and see it, it just bugs me. Surely it would have been cheaper for a slightly longer bit of plastic for the all mount, than to make and brand a bit of velcro.

The cable length under the hood wasn’t long enough, so I had to cut the wires and splice a longer cable in (same amp rating), so that I could route the cable where I wanted it to be out of sight but also easy access at the front of the car once in the garage. This supposedly half hour swap of charger took me about three hours by the time I took the car battery out, remade the cable, re-routed the cable, cleaned the area thoroughly, reinstalled the car battery and clamp, mounted the unit on the wall and cleaned up.

So far the new unit looks to be doing it’s thing as I would expect. However, I did notice that the maintenance cycle (slow green pulse LED) took a while to initiate as I suspect the charger was stabilising the battery from what it had been left with from the CTEK.

The one function I’m missing though is the LED lights on the CTEK connector. This was a simple traffic light idea for the status of the battery charge.

It’s not the end of the world of course, but a rather nice to have which I think NOCO should investigate for an option accessory purchase, I’m happy to test and review the item if you are reading this NOCO. I’m yet to decide on the final position of the new charger, so it’s not the neatest of fittings I have done. But for now it will serve a purpose until I can fully trust the new charger.

It wont be long now before the first car show is ready, so I will need to get the car out, fill it up with fuel and give it the de-winterising of the products I applied for protection. That usually takes me about a day all in. Hopefully I will be a little more regular with the posts again once the car shows start.

I have more reviews to add so look out for those too. I can’t wait to get my car out and go for a drive.
