How will temperature effect the performance of a battery?
A rule of thumb is that for every 7oC to 10oC rise in battery ambient temperature above 25oC, the expected life of the battery is reduced by 50%. Thus, a battery rated at 8 years on float at 25oC is only a 4 year battery at an ambient temperature of 32oC to 35°C. Conversely, every 10oC drop in the ambient temperature below 25oC will result in a 10% loss in battery capacity.
