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.
Putting it simply, a completely depleted ‘dead’ lead acid battery will freeze at 32°F (0°C). When a lead acid battery is fully discharged, the electrolyte inside is more like water so it will freeze”. (Jump down to chart) What happens when a lead acid battery electrolyte physically freezes?
5. Optimal Operating Temperature Range: Lead-acid batteries generally perform optimally within a moderate temperature range, typically between 77°F (25°C) and 95°F (35°C). Operating batteries within this temperature range helps balance the advantages and challenges associated with both high and low 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.
Failure mechanisms may be different but they are just as damaging as those created by higher temperatures. Operating lead-acid batteries at low temperatures, without temperature compensation will have damaging consequences for both the application and the battery. These are principally:
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.
