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.
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.
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.
Lead-acid batteries: A lead-acid battery should come with a smart charger that allows for voltage changes when sensing fluctuating temperature ranges. It should set the voltage higher when the battery is charged at lower temperatures and a lower voltage when charging at higher 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.
