It has a 2-year-old battery. Car sits a lot. Battery was charged for about 45 minutes, but was still weak, (car turned over).
After driving it for about 5 minutes, shut it off, sat for 10 minutes and it started right up as if it was never discharged.

Fluid level is fine in battery upon removal of caps.

Is there any chance one of those electrolyte solutions can help, even for a short time?

Or is there anything else I can do to rejuvenate the battery?

Thanks

A electrolyte solution is unlikely to rejuvenate your two-year-old battery. This is because of the effects of sulfation on battery plates. You might be able to use a disulfate, these devices can sometimes reverse the effects. I would just get a new battery.
