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?
The ideal charging voltage for a 12V lead acid battery is between 13.8V and 14.5V. Charging the battery at a voltage higher than this range can cause the battery to overheat and reduce its lifespan. How does temperature affect lead acid battery voltage levels? Temperature affects lead acid battery voltage levels.
A lead acid battery voltage chart is crucial for monitoring the state of charge (SOC) and overall health of the battery. The chart displays the relationship between the battery’s voltage and its SOC, allowing users to determine the remaining capacity and when to recharge.
The nominal voltage of lead acid is 2 volts per cell, however when measuring the open circuit voltage, the OCV of a charged and rested battery should be 2.1V/cell. Keeping lead acid much below 2.1V/cell will cause the buildup of sulfation. While on float charge, lead acid measures about 2.25V/cell, higher during normal charge.
Here is how it works: When the lead acid battery accepts charge, the sulfuric acid gets heavier, causing the specific gravity (SG) to increase. As the SoC decreases through discharge, the sulfuric acid removes itself from the electrolyte and binds to the plate, forming lead sulfate.
