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.
Discharging a lead acid battery below its recommended voltage can cause permanent damage to the battery. It can also reduce the battery’s capacity and lifespan. Therefore, it is essential to avoid discharging the battery below its recommended voltage level. This will ensure its long-term health and performance.
Temperature affects lead acid battery voltage levels. The voltage level of a lead acid battery increases as the temperature decreases and vice versa. Therefore, you need to consider the temperature when measuring the voltage level of a lead acid battery. At what voltage level is a lead acid battery considered fully charged?
Figure 5 : Chemical Action During Charging As a lead-acid battery charge nears completion, hydrogen (H 2) gas is liberated at the negative plate, and oxygen (O 2) gas is liberated at the positive plate.
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.
Charging at cold and hot temperatures requires adjustment of voltage limit. Freezing a lead acid battery leads to permanent damage. Always keep the batteries fully charged because in the discharged state the electrolyte becomes more water-like and freezes earlier than when fully charged.
