How Does Temperature Affect Batteries?
One of the most important factors of battery aging and performance is ambient temperature.
The optimum temperature range for a VRLA battery is 20-25°C. Higher ambient temperatures do actually improve performance but rapidly age a battery.
20°C is the optimum battery temperature. At 30°C, the battery design life halves.
If the ambient temperature around a battery set is not controlled, premature battery failure can occur resulting in a costly battery replacement, and invariably system downtime.
A battery failure due to over-temperature can also lead to complete system failure which would only become evident when the battery set is placed under load during a mains power failure.
