For a 12 volt lead acid battery, this is 20Ah. At the 8 hour rate, a 12 volt lead acid battery should provide 1.5 amps. Most batteries are actually rated at the 10 hour rate, which would be 2 amps for a 12 volt lead acid battery. However, some manufacturers use different terms such as “C/20” or “2C” to express the capacity of their batteries.
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.
For lead acid batteries the rated capacity (i.e. the number of AH stamped on the side of the battery) is typically given for a 20 hour discharge rate. If you are discharging at a slow rate you will get the rated number of amp-hours out of them. However, at high discharge rates the capacity falls steeply.
The actual capacity of a lead acid battery, for example, depends on how fast you pull power out. The faster it is withdrawn the less efficient it is. For deep cycle batteries the standard Amp Hour rating is for 20 hours. The 20 hours is so the standard most battery labels don’t incorporate this data.
The voltage of a lead-acid battery also varies with temperature. At room temperature, the voltage of a fully charged lead-acid battery is around 12.6 volts. As the temperature of the battery decreases, the voltage of the battery also decreases. Similarly, as the temperature of the battery increases, the voltage of the battery also increases.
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?
