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.
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.
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.
Temperature plays a crucial role in the performance and longevity of lead-acid batteries, influencing key factors such as charging efficiency, discharge capacity, and overall reliability. Understanding how temperature affects lead-acid batteries is essential for optimizing their usage in various applications, from automotive to industrial settings.
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.
Charging at cold and hot temperatures requires adjustment of voltage limit. Freezing a lead acid battery leads to permanent damage. Always keep the batteries fully charged because in the discharged state the electrolyte becomes more water-like and freezes earlier than when fully charged.

Past, present, and future of lead–acid batteries | Science
When Gaston Planté invented the lead–acid battery more than 160 years ago, he could not have foreseen it spurring a multibillion-dollar industry. Despite an apparently low energy density—30 to 40% of the theoretical limit versus 90% for lithium-ion batteries (LIBs)—lead–acid batteries are made from abundant low-cost materials and nonflammable …

Low-temperature charging behaviour of lead-acid cells
At −18°C the charge acceptance rates fell within a range of 20 to 40% of that observed at 25°C. The highest rates at −18°C were favoured where the charge followed a high-rate, low-temperature discharge, with a minimum time and temperature for the open circuit stand.

Low-temperature charging behaviour of lead-acid cells
The effect of temperature on the charging behaviour of lead-acid cells was studied at a depth of discharge of ∼20% of their reserve capacity. As expected the charge acceptance rates dropped markedly at temperatures below 0°C. The ability to charge at these temperatures was limited by a precipitous increase in polarization at the negative plates which occurred immediately upon …
