Temperature Control: Ideally, lead-acid batteries should be charged at temperatures below 80°F (27°C). Charging at high temperatures can lead to thermal runaway, where the battery overheats and becomes damaged. If your battery becomes hot to the touch during charging, stop the process immediately and allow it to cool. 4. Avoiding Overcharging
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.
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.
Temperature plays a crucial role in the performance and longevity of lead-acid batteries, influencing key factors such as charging efficiency, discharge capacity, and overall reliability. Understanding how temperature affects lead-acid batteries is essential for optimizing their usage in various applications, from automotive to industrial settings.
Lead acid is sluggish and cannot be charged as quickly as other battery systems. (See BU-202: New Lead Acid Systems) With the CCCV method, lead acid batteries are charged in three stages, which are constant-current charge, topping charge and float charge.
Under the right temperature and with sufficient charge current, lead acid provides high charge efficiently. The exception is charging at 40°C (104°F) and low current, as Figure 4 demonstrates. In respect of high efficiency, lead acid shares this fine attribute with Li-ion that is closer to 99%.
The final impact on battery charging relates to the temperature of the battery. Although the capacity of a lead acid battery is reduced at low temperature operation, high temperature operation increases the aging rate of the battery. …
