This is called thermal runaway and it can destroy a battery in as little as a few hours. Lead Acid Battery Cycle Charging. Cyclic (or cycling) applications generally require recharging be done in a relatively short time.
Lead acid batteries get warm during charging because of heat generation from chemical reactions and internal resistance. This warmth is normal, but excessive heat can harm the battery''s efficiency and life span. Monitor the battery''s temperature regularly to ensure proper operation and prevent overheating issues.
During a thermal runaway event, the battery will self-discharge its entire capacity in a matter of minutes! The by-product of discharging so fast is an excessive amount of heat – and all of that energy has to go somewhere. Most commonly, this presents itself as a swelled battery – the battery will bulge from all sides.
Lead-acid: Lead acid is reasonably forgiving when it comes to temperature extremes, as the starter batteries in our cars reveal. Part of this tolerance is credited to their sluggish behavior. The recommended charge rate
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." This
To enable fast charging at all temperatures, some industrial batteries add a thermal blanket that heats the battery to an acceptable temperature; other chargers adjust the charge rate to prevailing temperatures.

thermal runaway of safety and service life of the lead-acid battery constitutes a serious threat. By understanding its causes and taking preventive measures, users can minimize the risk of thermal runaway while taking full advantage of lead-acid batteries. With proper use, monitoring and maintenance, the possibility of catastrophic failure can be significantly reduced,
Also, it is good to look from the cell at atomic scale through the thermal system design to the charging algorithms and handshakes. The drive for a 10 min fast charge to reach 80% state of charge is tough against the other pressures of
Thermal Runaway is defined as a critical condition arising during constant voltage charging in which the current and the temperature of the battery produces a cumulative, mutually reinforcing effect which further increases them, and may lead to the destruction of the battery.
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.”
Thermal management of lead-acid batteries includes heat dissipation at high-temperature conditions (similar to other batteries) and thermal insulation at low-temperature conditions due to significant performance deterioration.
A lead acid battery charges at a constant current to a set voltage that is typically 2.40V/cell at ambient temperature. This voltage is governed by temperature and is set higher when cold and lower when warm. Figure 2 illustrates the recommended settings for most lead acid batteries.
Temperature Control: Ideally, lead-acid batteries should be charged at temperatures below 80°F (27°C). Charging at high temperatures can lead to thermal runaway, where the battery overheats and becomes damaged. If your battery becomes hot to the touch during charging, stop the process immediately and allow it to cool. 4. Avoiding Overcharging
Choosing the Right Charger for Lead-Acid Batteries The most important first step in charging a lead-acid battery is selecting the correct charger. Lead-acid batteries come in different types, including flooded (wet), absorbed glass mat (AGM), and gel batteries. Each type has specific charging requirements regarding voltage and current levels.
To charge a sealed lead acid battery, a DC voltage between 2.30 volts per cell (float) and 2.45 volts per cell (fast) is applied to the terminals of the battery. Depending on the state of charge (SoC), the cell may temporarily be lower after discharge than the applied voltage. After some time, however, it should level off.
