Are terminals the same size? ( stock battery u vs optima) A connection that isn't tight enough will get hot. Also check your grounds and positive cables for shorts.

Is a block heater to keep the engine warm?

Yep, for use in the winter to keep it warm and make it easier to start when the temps get below 20 or so, might have a peak in the owners manual for the correct temp.

On my Chevy 3500 with the diesel motor I had one but it said NOT to use it unless it got below 25 IIRC.
