Yes, it is in the engine compartment but fairly far from the engine and
  low in the compartment with free air space on all sides. It does not
feel very warm to the touch after long drives. Most cars have their
batteries in the engine compartment, mounted higher and with a lot less
space around them than I have.

It may just be a battery quality issue. It had 3 weak cells according to
my hydrometer. The big box retailer swapped it for a new one after only
a small struggle. It has an 18 month free replacement warranty and was
11 month in. Strangely, they gave me a new receipt so the 18 months
begins again.
