Replaced my battery 3 / 4 weeks ago. Jeep started right up, nothing was lost except the EQ (Bass / Mid /Treble) settings.

That has happened to me before, but usually its not an issue. I think I left the battery out for like 12 hours at the time when I was charging and testing it.

Check all the leads, last summer a failed but later tested good battery was the result of a bad ( Corroded) ground
$100 tow for a $12 part.
