I’ll apologize for the length in advance. I’ve had this truck since July of last year. New battery had just been installed when I bought it. Ran flawlessly until one morning in January when it wouldn’t start. Fine when I parked it that night, woke up to go to work and it just clicked. Took the wife’s car to work. Came home for lunch, jumped the battery. Started right up. Took the truck back to work. Went back out after work, click. Had a coworker jump me, went directly to the part store to have them test the alternator and battery. Left the truck running fearing it wouldn’t start again, but they said they’d need to turn it off to test it. Couldn’t take that chance. Knowing I had a 5 month old battery, I assumed it was the alternator, so I just bought a new one. Charged the battery while I installed the new alernator. Got it all done, started the truck no issue. Came out to go to work the next day, click. Took the battery out of the truck and tested it every hour for 8 hours, and it slowly kept dropping in voltage. Took the old alternator and the battery to a part store and had them test both. They tested them both twice and said both were good. I bought a new battery anyway and installed it. Truck started right up. I did some parasitic drain testing just to be safe with the new battery and new alternator in the truck and it did exactly what it was supposed to do. Started with a bit of a draw when connected and after about 7 minutes or so of various systems doing there thing, it dropped down to where it was supposed to be. Trucks been running perfect for the past 2 1/2 months. This morning, go out to go to work, click. Jumped it, started right up. Went to work, let it run about a 1/2 hr in the parking lot, shut it off and continued my day at work. Went out for lunch about 5hrs later, started right up. Came out after lunch, click. Hooked up a charger on 2amp setting, took the wife’s car back to work. Came home, waited until about 7pm, unhooked the charger, tested the battery 12.95V. Tried to start it, click. Tested the battery again 12.46V. Jumped the battery, started right up. Checked the battery while running 14.66V. Let it run for about 25min, turned it off. Checked the battery 12.86V. Tried to start it, click. Checked the battery 12.41V. Truck is now sitting in the driveway and won’t start if I don’t jump it. Anyone have a similar issue? What am I missing?
UPDATE
Tested battery this morning after letting it sit overnight, 12.41V, so no voltage drop or parasitic drain happening.
