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.

The effect of low temperatures on lead batteries

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.

Heat Effects during the Operation of Lead-Acid Batteries

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."

BU-804: How to Prolong Lead-acid Batteries

The solubility of lead in battery acid is very approximately 4 parts per million. The charge-discharge and discharge-charge reactions proceed regardless of lead''s low solubility because lead is able to move around quite easily across the surface formations of the electrodes.

Battery Charging at Low Temperatures

Li-ion can operate to a temperature of –40 o C but only at a reduced discharge rate; charging at this temperature is out of the question. With lead acid there is the danger of the electrolyte freezing, which can crack the enclosure.
