New battery already bad??
2013 Ford F-150 5.0. I replaced the battery Friday. Started the truck up great for the rest of the day. Started up fine Sat AM, but after sitting at work all day Saturday, it kinda slow cranked...

Did you fully CHARGE the new battery before use ? Most need that initial charge.
Then....you need to take the whole truck back to the "battery store" so they can test the battery AND the alternator.
P.S. The 12 V gauges and/or idiot lights are useless....because even a failed alternator seems to put out just enough so the light won't trigger and the needle isn't off enough so you can tell.
