In exide batteries manual it was mentioned that, "if battery room temperature is maintained high, then life of battery will reduce but capacity will remain same. But if battery room temperature is less, then life will be more but capacity will be less."

In this case, how temperature is affecting battery capacity?

Vinu... contact Dynasty Technology for their paper, "Batteries, Life Expectancy vs Temperature"!

Battery Capacity means the ability to provide output current, or precisely AH (ampere hours). Battery life means the capability to provide capacity over a period of time.

As these batteries depend on a chemical reaction which has increased activity at higher temperature and reduced activity at lower temperature, the statement on capacity.

Putting aside the long story, higher temperatures also promote degradation within the cells due to corrosion of cell electrodes and change of electrolyte composition. This will eventually cause breakage of electrodes and reduce life.
