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...

Lead acid batteries perform better in warm weather but hot weather shortens their life. You can’t regulate air temperature but to can shade the battery box from direct sunlight.
Per Trojan…”For every 18° F (10° C) rise above room temperature (77° F or 25° C), battery life decreases by 50%. Charge your batteries fully after each period of use. Allowing your batteries to sit in a low state of charge for extended periods will decrease their capacity and life.”
