If the batteries were making poor contact with the negative spring,

OK that's plausible. I'll stretch the springs out even more.
I doubt that is it. Remotes draw very little current for very short
periods of time. I poor connection would cause eratic behavior, but
not a lot of heat. I suspect the batteries were somehow shorted
thereby causing the current to be only limited by the battery's
internal resistance. That would heat the batteries.
