How Does Temperature Affect Lead Acid Batteries?
What we do know is that operating at a higher temperature will reduce the life of lead-acid batteries. We should also consider the battery configuration and thermal management. If, for example, the battery is arranged on a 6 tier stand that could easily be over 2m high, it is not uncommon for there to be a 5ºC difference between the bottom and
How Heat Affects VLA and VRLA Lead-Acid Batteries
While VLA batteries handle heat better than VRLAs, because the electrolyte is always in contact with the cell container for better heat dissipation, VRLAs will also fail sooner when used in poorly ventilated UPS applications. Even though a battery operating at a high temperature can show increased capacity at times, the life of the battery will

Will a lead-acid battery accept more current if temperature increases?
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.
