This blog covers lead acid battery charging at low temperatures. A later blog will deal with lithium batteries. Charging lead acid batteries in cold (and indeed hot) weather needs special consideration, primarily due to the fact a higher charge voltage is required at low temperatures and a lower voltage at high temperatures.
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.
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.”
Heat is the worst enemy of batteries, including lead acid. Adding temperature compensation on a lead acid charger to adjust for temperature variations is said to prolong battery life by up to 15 percent. The recommended compensation is a 3mV drop per cell for every degree Celsius rise in temperature.
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.
Advantages: Lower temperatures often result in a longer service life for lead-acid batteries. Challenges: Discharge capacity decreases at lower temperatures, impacting the battery’s ability to deliver power during cold weather conditions.

High temperature results in enhanced reaction rate and thus increasing instantaneous capacity but reduces the life cycle of a battery. Every 10°C rise in temperature reduces the life of a battery to half of its rated value [4].
The lead-acid battery system is designed to perform optimally at ambient temperature (25°C) in terms of capacity and cyclability. However, varying climate zones enforce harsher conditions on automotive lead-acid batteries. Hence, they aged faster and showed lower performance when operated at extremity of the optimum ambient conditions. In this ...

The freezing of battery electrolyte often occurs when the battery is undercharged and exposed to low temperatures. This is because when a battery is fully charged, the water and acid in the electrolyte are combined. …
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."
When charging lead acid batteries, it is essential to stay within the recommended temperature range provided by the manufacturer. Excessive heat or cold can negatively impact the battery''s performance, reduce its charge acceptance, and even cause permanent damage.
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. …
The risks in charging an industrial battery: The charging of lead-acid batteries can be hazardous. However, many workers may not see it that way since it is such a common activity in many workplaces. The two primary risks are from hydrogen gas formed when the battery is being charged and the sulfuric acid in the battery fluid.
Charging lead acid batteries in cold (and indeed hot) weather needs special consideration, primarily due to the fact a higher charge voltage is required at low temperatures and a lower voltage at high temperatures.
