Camaro brand charger/tender

Richiefcknrich · 08-08-2022, 04:58 AM

Hello everyone had this camaro tender for about year and a half now and it’s not going to green even after hours on the car. Not able to warranty it so just checking in to see if I am missing something before I trash it and get a differnt one.
If it’s on the car a few hours and I unplug then replug in to the wall it goes green for a few mins then back to red.
Thanks for any help.
Also our factory batteries are AGM correct?
If I replace our Walmart has the pictured below, any good?
Thank

Have your battery tested. It could be the charger, but it's more likely the battery.

Mine did the same thing on a brand new CAMARO tender unit you have shown and a basically brand new car

That's a CTEK rebranded by GM.

Not sure about wal-mart's price. I got a CTEK MXS 5.0 off amazon for about $85. I would recommend you go with a charger that has a dedicated AGM mode (not a dual-mode) if you have an AGM.

I have a working GM charger that is, as ctrlz says, a rebranded CTEK, but I'm no longer using it because it got replaced by a fancy Optimate 6

Richie, if you want my old GM charger as a quick free stopgap, it's yours, just pay for shipping.

I too have and regularly use a CTEK MXS 5.0. Two of my 3 cars are non-AGM, so it's nice to be able to need only one unit that can switch modes.

Battery is still 12.82v day after driving and after almost 4 weeks of sitting it’s 12.63v. Hook up the GM branded maintaining charger it stay red(picture below). Is this charger bad? I can’t find where others have had this issue so it’s hard for me to just write it off as bad charger. From what I read from the voltages I have I can’t imagine the battery is bad?
I let it charge for about 3 hours last night no change , light stayed red, before it’s was hour or so and light went green.
Let me know what you guys think.
Thanks
Richie

Looks like a re logo'd C Tek to me. Check out their website, I think it's an MXS 5 or something like that that I have,....a brilliant device,....leave it on as long as you like, it will keep your battery in good shape.
