Does hot weather affect battery performance?
I have four 12 volt lead acid deep cycle batteries in a vented metal box on the tongue of my Toy Hauler. We recently have gone through several days of 100 degree temps. Made me start thinking about...

Look no further than your car/truck for that answer. A car battery in Phoenix Arizona lasts 2 years. A car battery in San Francisco lats 5-7 years. A car battery in Buffalo NY lasts 4 years. Heat kills a battery faster than anything.
Concur ! At least for lead-acid batteries. That is why many manufacturers are putting insulating sleeves around the battery or in a few cases moving them out of the engine compartment.
I have two vehicles where the battery is NOT in the engine compartment. One has the battery under the rear seat, the other in the trunk. And in those to cases batteries tend to last 10+ years. Now part of the reason for the battery location likely as little or nothing to do with heat and more to do with weight distribution getting close to 50/50. 75lbs more in the trunk is much better than 75lbs more over the front axle.
