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.
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.
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.
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.
Lead-acid batteries contain lead grids, or plates, surrounded by an electrolyte of sulfuric acid. A 12-volt lead-acid battery consists of six cells in series within a single case. Lead-acid batteries that power a vehicle starter live under the hood and need to be capable of starting the vehicle from temperatures as low as -40°.
This article demonstrates how a lead-acid battery can be unknowingly used and abused simply by not recognising the need for temperature compensations in the charging and discharging of a battery during cold weather periods. The problems associated with cold temperature operation for lead-acid batteries can be listed as follows:

Thermal Considerations of Lithium-Ion and Lead-Acid Batteries
Low temperatures reduce the output of a lead-acid battery, but real damage is done with increasing temperature. For example, a lead-acid battery that is expected to last for 10 years at 77°F, will only last 5 years if it is operated at 92°F, and just a year and a half if kept in a desert climate at a temperature of 106°F. Starter batteries ...
