Yes, cold weather does affect the capacity of a lead acid battery. Cold temperatures reduce the chemical reactions within the battery. In colder conditions, the electrolyte solution, usually a mixture of water and sulfuric acid, becomes less effective. This decreases the battery’s ability to produce electric current.
Undercharging, due to lack of low temperature voltage compensation, leads to low specific gravity (SG) of the electrolyte in a battery. The SG in a discharged battery is higher at low temperatures than it would be under standard operating conditions. This is due to the normal SG variation with temperature of any liquid.
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.
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.
Other consequences arising from low-temperature operation, include reduction in both on-charge gas evolution and battery capacity. Whilst water loss is more of a problem with higher temperatures, insufficient gassing due to charging at low temperatures may result in inadequate electrolyte stirring.
A fully charged lead-acid battery performs better in cold temperatures. In cold conditions, a lead-acid battery should be kept at a minimum of 75% charge. Regularly checking and charging the battery can help prevent damage. Using insulation methods can also lessen the impact of cold weather.
