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.

Thus, under certain circumstances, it is possible to lower the temperature of the lead-acid battery during its discharging.

How does temperature affect battery life?

Of course, there are also correlations between them. For example, if battery capacity is reduced by temperature, the relative death of discharge (DoD) increases when taking out the same amount of energy and so lifetime is reduced. The next important thing is what happens with the battery at this different temperature.
