Characteristics of Lead Acid Batteries
The production and escape of hydrogen and oxygen gas from a battery cause water loss and water must be regularly replaced in lead acid batteries. Other components of a battery system do not require maintenance as regularly, so water loss can be a significant problem. If the system is in a remote location, checking water loss can add to costs. Maintenance-free batteries limit the

How do thermal events affect lead-acid batteries?
Thermal events in lead-acid batteries during their operation play an important role; they affect not only the reaction rate of ongoing electrochemical reactions, but also the rate of discharge and self-discharge, length of service life and, in critical cases, can even cause a fatal failure of the battery, known as “thermal runaway.”
How does voltage affect a lead-acid battery?
Thus, the maximum voltage reached determines the slope of the temperature rise in the lead-acid battery cell, and by a suitably chosen limiting voltage, it is possible to limit the danger of the “thermal runaway” effect.
What causes thermal runaway in lead-acid batteries?
For thermal runaway to occur in vented lead-acid batteries, very high extremes of charging current and the resultant high temperature must be present. While this document only considers thermal runaway in VRLA AGM products many of the causes are also applicable to GEL types.
Are lead-acid batteries causing heat problems?
Heat issues, in particular, the temperature increase in a lead-acid battery during its charging has been undoubtedly a concern ever since this technology became used in practice, in particular in the automobile industry.
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.
Is there a cooling component in a lead-acid battery system?
It was found by calculations and measurements that there is a cooling component in the lead-acid battery system which is caused by the endothermic discharge reactions and electrolysis of water during charging, related to entropy change contribution.
