At extremely low temperatures, such as -40°C (-40°F), the charging voltage per cell can rise to approximately 2.74 volts, equating to 16.4 volts for a typical lead-acid battery.
Battery capacity falls by about 1% per degree below about 20°C. However, high temperatures are not ideal for batteries either as these accelerate aging, self-discharge and electrolyte usage. graph shows the evolution of battery function as a number of cycles and depth of discharge for a shallow-cycle lead acid battery.

This wear-down characteristic applies to all batteries in various degrees. (See BU-804:How to Prolong Lead Acid Batteries) Charging a lead acid battery is simple, but the correct voltage
The lead acid chemistry likes to be close as possible to 100 percent charge. A car battery will get f''ed up if you discharge it below 50% a few times whereas a deep cycle lead acid battery will handle below 50% for hundreds of cycles. But keeping a deep cycles above 50% at all times is crucial to keeping its lifespan up.
The 6 cell Lead Acid battery should ideally be charged at 13.8V to 14.7V. Any lower and you wouldn''t be able to reach full charge and any higher and the battery might get heated up and might get damaged . If the battery voltage is higher than your charging voltage current will start flowing in the opposite direction and thus discharging the

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.
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.
Discharging lead acid batteries at extreme temperatures presents its own set of challenges. Both low and high temperatures can impact the voltage drop and the battery's capacity to deliver the required power. It is important to operate lead acid batteries within the recommended temperature ranges to maximize their performance and lifespan.
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.
Here are some key points to keep in mind: 1. Reduced Charge Acceptance: At low temperatures, lead acid batteries experience a reduced charge acceptance rate. Their ability to absorb charge is compromised, resulting in longer charging times. 2. Voltage Dependent on Temperature: The cell voltages of lead acid batteries vary with temperature.
