6 FAQs about [Temperature tolerance of lead-acid batteries]
How hot should a lead-acid battery be?
Only at very high ambient air humidity (above 70%), water from outside the battery can be absorbed by the hygroscopic sulfuric acid. In summary, the internal temperature of any lead-acid battery (flooded and AGM) should not exceed 60 °C for extended time periods frequently to limit vaporization. 2.1. External and internal heating of the battery
Can you lower the temperature of a lead-acid battery during discharging?
Thus, under certain circumstances, it is possible to lower the temperature of the lead-acid battery during its discharging.
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.
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.”
Why is temperature important for automotive batteries?
The battery's temperature is one of the most significant parameters for the service life of automotive batteries. Low temperatures may be critical due to freezing of the electrolyte, in particular at low states of charge (SOC). High temperatures may accelerate the ageing of batteries, resulting in premature end of service life.
What temperature is a battery heated at?
All our experiments have been carried out in a thermo chamber at temperatures up to 60 °C. Under these conditions, the batteries are heated nearly uniformly, which means that all parts of the battery, including the lid and the valves, were on the same high temperature level.
