The question the battery supplier will be asking is: Why has the battery died?
You will need an unquestionable answer, because he will be blaming it on everything possible to avoid giving you a free replacement battery given the opportunity, and on the other hand you will want to know because it probably will happen again if you don't fix the problem now!
Were the alternator recharge voltages as specified for the battery?
Were any wires loose or with lugs not correctly fitted?
Heat could be a problem, but not a major one with a small engine block.
How long did the previous battery last under the (exact) same conditions?
If it had been a red, blue or yellow top, makes no difference, it would still be dead because it is not the battery specs, but the condition of the battery, possibly due to the lack of correct charging, or if you say the heat is really EXCESSIVE then the battery may have died from heat exhaustion.

Yeah Mainy, all sounds fair an resonable. I've done a lot of electrical work on this particular car and have a good quality third party volt meter sitting on the dash which I installed myself and it has always been suprisingly good on charge rates etc. Almost ALWAYS 14.2 volts continuously, no matter what the ambiant temp and load. I mean my charging system is all over the frigin place depending on how I hold my mouth when I look at the meter! ;-)
I checked all the connections out there and there didn't seem to be any impedance problems or shorts. That was my first thought was that something unfused has shorted (maybe an alternator connection or similar) and has flattened the battery, but now that we've pulled the battery out and it's completely poo, and the car ran fine on one of my old POS batteries I had lying out near the shed you gotta wonder what happened..?? I know there was a lot of heat under the bonnet as I could hardly touch the anything under the bonnet without buring my hands, and my car had to have a few rests between plays as the temp guage was heading a little north on a few occasions, but still they are supposed to be better in the heat than standard bat's....

If it has a CCA rating then it is meant for starting. So should not be a drama as a cranking battery.
However, excessive heat may well be the problem.
I personally find the Exide Extreme very good value, especially on Kmart 25% off everything days!
My current one has been installed for 3 years now and still gives good service. Note that the Extreme has a CCA as well as RC and Ah rating, so it can be used for deeper discharges than a normal cranking. When the fridge has been run overnight on it, it will take quite a few hours to fully recharge. However, the last couple of hours it will take only 2-5 amps, and that means really that it is already about 90% full.
