The problems associated with cold temperature operation for lead-acid batteries can be listed as follows: Increase of the on-charge battery voltage. The colder the battery on charge, the higher the internal resistance.
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
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. The battery temperature is mainly determined by external factors like climate conditions and battery packaging.
Thus, under certain circumstances, it is possible to lower the temperature of the lead-acid battery during its discharging.
Similar with other types of batteries, high temperature will degrade cycle lifespan and discharge efficiency of lead-acid batteries, and may even cause fire or explosion issues under extreme circumstances.
Most battery users are fully aware of the dangers of operating lead-acid batteries at high temperatures. Most are also acutely aware that batteries fail to provide cranking power during cold weather. Both of these conditions will lead to early battery failure.

As low-cost and safe aqueous battery systems, lead-acid batteries have carved out a dominant position for a long time since 1859 and still occupy more than half of the global battery market [3, 4]. However, traditional lead-acid batteries usually suffer from low energy density, limited lifespan, and toxicity of lead [ 5, 6 ].
The lead acid battery uses the constant current constant voltage (CCCV) charge method. A regulated current raises the terminal voltage until the upper charge voltage limit is reached, at which point the current drops due to saturation. The charge time is 12–16 hours and up to 36–48 hours for large stationary batteries. With higher charge currents and multi-stage …
