Using Jump Start terminals for trickle charger?

Thanks for the info Kaz - much appreciated. Will look into adding an inline fuse to give myself a bit more protection.

Cheers!

Fitted the ctek this morning. Changed the 3 pin plug into a waterproof connector that then connects to an outdoor rated lead into my garage (NSX currently parked outdoors)

All seems to be working ok - thanks for the info guys.

Without wishing to cause any unnecessary worries, the use of the CTEK MX5 seems to have killed my NSX's battery. It was working fine for several weeks - the string of LEDs showing progress illuminated and then changed as normal = all healthy. And then one day the string of LEDs was not lit.

Now, when disconnecting and reconnecting, the CTEK doesn't seem to think there's a battery attached.

I will investigate more this week.

I have a CTEK MX5 - it has been used without any problems since 2018.

Yes, this one has worked fine for several months. I checked it every morning.

Am hoping it was just a bad battery.

did the ctek get switched off at the power source?

i found that if its not powered up, but still connected to the battery it WILL discharge the battery completely. so if you want to switch it off overnight, for example, i HAVE to unclip it from the battery too

and i have found if a battery is very flat i have to give it a kick with a conventional battery charger, to get enough voltage for the ctek to recognise a battery is connected

Not switched off, as far as I know. Unless there was a power cut at the workshop?

(Bizarre that the CTEK wouldn't have a simple diode fitted to stop discharge of the battery!)

Hopefully you'll figure out what happened. You can get a battery health tester to see what condition the battery is in. Like you say it probably was that
