Lead–Acid Batteries

For flooded lead–acid batteries and for most deep-cycle batteries, every 8 °C (about 15 °F) rise in temperature reduces battery life in half. For example, a battery that would last for 10 years at 25 °C (77 °F) will only be good for 5 years at 33 °C (91 °F). Theoretically, the same battery would last a little more than 1 year at a desert temperature of 42 °C.
