Mr Tuna: When it got to me, it was at 12.39v. A bad sign already. On the smart charger, it got up to 12.85. I couldn't get it any higher with the megawatt at 14.7 volts.
I'm not a battery expert, but I thought this seemed like it is probably a POS. Is that right?
Not necessarily. Many are fully charged at 12.84V. Depend on the manufacturer.
That came up in the other thread, right? And Mex said no, they really should be over 13? I don't think you replied to him. I thought that meant that you agreed with him, but maybe you were just being polite?
Do you (or anyone here) know what voltage a full charge should be on a Johnson Control battery? I don't think they have a customer-facing helpline, do they? And the guys at the local AutoZone don't even know that AGM are different from wet.
Edit: Well whattaya know, I found a customer service number for them. Not open till Monday of course. Putting it on my list.
