On the subject of battery life and heat, I have to mention that I live in one of the hottest places in the US, near Phoenix, Arizona, and have never seen a problem with battery life due solely to heat. Common daily high temperatures here from mid-May until the end of September are 105F to 115F. The batteries in all my vehicles last at least three and usually closer to five years. I have a 2017 Honda CRV (battery died at about three years), a 2000 Ford F-150 that usually requires a battery at a little over three years, a 1923 Ford with a six-volt battery that lasts about four years. The other two motorcycles got over three years life out of their batteries and the Miata, which was killed by a twenty-ton gravel truck, got at least three years and I am thinking it was closer to five years out of it's battery. While all my vehicles are garaged except the truck, my garage is unbearably hot in the summer. All the batteries are common lead-acid batteries available at any automotive parts store. Hope this helps.
