Do batteries last longer in hot climates than in cold ones?

Batteries used in colder or moderate conditions can last between twice and three times as long as batteries used in hot climates. Heat kills batteries! Keep your alkaline batteries in the fridge! In the northern states or Canada the life expectancy of a battery is between 48 and 54 months. In the Southern States like Florida the average life expectancy of standard batteries is about 18 to 23 months. This data is based on normal usage and very good charge and discharge conditions. Temperature is a MAJOR contributor to deep cycle battery life and performance. You will experience longer life in moderate (not hot) environments, and you will see reduced performance or run time in colder environments.
