SOME FACTS ON THE SUBJECT OF AMBIENT OR OPERATING TEMPERATURE. As a general rule, Banner recommends an operating temperature of max. -40 to +55 degrees Celsius; optimum storage conditions are approx. +25 to +27 degrees Celsius. These criteria apply to all lead-acid batteries and are valid for conventional, EFB, AGM and GEL technology.
Temperature effects are discussed in detail. The consequences of high heat impact into the lead-acid battery may vary for different battery technologies: While grid corrosion is often a dominant factor for flooded lead-acid batteries, water loss may be an additional influence factor for valve-regulated lead-acid batteries.
Lead-acid batteries will accept more current if the temperature is increased and if we accept that the normal end of life is due to corrosion of the grids then the life will be halved if the temperature increases by 10ºC because the current is double for every 10ºC increase in temperature.
It is well known that all lead-acid batteries will have a shorter life when operated at a higher temperature. This is the case no matter what type lead-acid battery it is and no matter who manufacturers them. The effect can be described as the ARRHENIUS EQUATION.
In any case, good quality lead-acid batteries will not normally fail due to drying out. Drying out is not relevant to vented types and we can use the Arrhenius equation to give an estimate of the life when the operational temperature is different to the design temperature.
The higher the temperature, the faster chemical processes such as self-discharge take place in the battery, with massive repercussions for its service life. Heat effect For this reason, the ambient temperature must not exceed +55 degrees Celsius.
