Ok so I use my OEM charger when i know the car is going to sitting for a week or longer.
I plugged it up this week as I normally do but after a few days I was in the garage and I hear this buzzing noise coming from the charger and the light was on the second half battery icon. i unplugged it for for a few days then plugged it back in again and I got the same noise same icon.

Have anyone experience this and what could be the issue?

Should I just get a replacement?

Thanks.

 

I had the same thing happen to my OEM Aston CTEK charger. I contacted CTEK they said take it back to my Aston Dealer--Right! 400-miles round trip. So I returned it to CTEK and asked them to fix it and I would pay the repair costs. Two weeks later I got it back, no repair, no note, no customer service. Don't waste your time, buy a replacement CTEK on Amazon.

 

Thanks that's what I thought, Time for a replacement.

 

Could i cut the cigarette lighter portion of the AM charger and wire it to the the CTEK mud 4.3 model?

 

Here's an easier, cleaner way and what I did.
Go to Amazon and buy this: CTEK 93-56-864 MUS 4.3 Black 12V Battery Charger

Then get this Adapter:CTEK (56-870) Comfort Indicator Cig Plug

 

Thanks will do.
