Truck wont start after parked on slant

JaysFinishing

So i was cleaning my garage and had my truck parked on about a 30 deg slant (driver side lower than passenger side) beside garage as i was emptying into it. After about 3 hours i went to go move truck into garage and absolutely nothing when i turned key.

Before this was out 2 or 3 times and no issues and nothing prior to identify a possible problem.

I put charger on it and said full charge so tried to boost and when trying to turn over just click of starter eventually got it going drove around and came back, tried it later and turned over fine.

Went this morning and battery still had charge but as soon as i went to turn over nothing. Tried boosting just click.

Battery test was fine. Any ideas.

It worked fine and had no issues prior to it being on the slant parking, so thinking something to do with that but see no leaks underneath.

Hello! Sounds like a loose or corroded battery terminal. Clean booth terminals and apply die-electric grease. Be sure they are tight, but do not over tighten as this can break the battery post or connector. Good luck!
