Cool Out-of-storage electrical weirdness

2014 Sunseeker 2500TS

So this happened:
I messed up and let the coach (van) battery fully deplete over the winter. Had a tow truck jump, engine finally started, engine gauges normal, but.....RPMs cycled between only 300-700 or so, every 8-10 seconds, gas pedal dead, panel annunciators wierd. I thought: funky fuel? air blockage? I let it continue for 5-8 minutes, then had to leave. Shut it down, then right back up, and it ran Normally, so I drove it to my home. The battery may be shot, still shows red dot. The only not-normal thing now is the battery discharge indication (red dot), and the leveler warning beep is constant, though they remain retracted. I know there are electronics all around, but wanted to get any early feedback from you good ole' boys. WTF?
Battery's on the charger now.

Those computers seeing low voltage or spikes will do some weird things. The programming will glitch as it's running.

If the battery was completely dead, it's probably best to just invest in a new one. I'd at least have it load tested after you charge it.
