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.”
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
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.
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.
In normal circumstances battery terminals are not supposed to get hot. If every connection is tight and clean out of the corrosion heat shouldn’t be present. In case you touched your terminals right after you cranked up the engine and it takes longer than usual, you can expect terminals to be slightly warm to the touch.
Thus, under certain circumstances, it is possible to lower the temperature of the lead-acid battery during its discharging.
What is a Battery Terminal?
You can also identify battery terminals by their color; the positive terminal is often red, while the negative terminal is black. What functions do battery terminals serve in a circuit? Battery terminals serve two primary functions in a circuit. First, they provide a secure and stable connection between the battery and the rest of the circuit.
