I have a battery tender and I use it, I was just wondering why my battery loses energy so fast. This morning I did not even hook up the battery tender yet and it was back up to 12.5V even though last night it said 12.0V.
Well, my car is showing 12.0V with my car off. It will show 13.0V then 12.5 V and rest at 12.0V after a total of about 10 seconds total. ford has said nothing is wrong but something has been wrong after I had my car for about five months.
Replaced my battery after ford told me that my battery was fine (4-5 times). Seems like they were wrong. I started telling them about it after I had my car for about five months.
Yes, I have received these questions in my C6, C7, and now my Mach 1. Funny that my 2013 SVT Raptor I did not, it was black so people just thought it was a regular truck since you could not really see its SVT name.
When people ask how much my Mach 1 was and I tell them they always ask why did you pay that much for a car. They usually will go they would not pay that much for any car.
I bought a new battery. I charged it to 100%, reset BMS, let it sit for eight hours, and then drove my car around. I think it is good now, accessories mode on 12.5V, car running 14.5V. Seems like ford missed the battery being bad the four or five times I went there and had them check it.
