Lead Acid Battery Voltage Drop Under Load at Latoya Cannon blog

Lead Acid Battery Voltage Drop Under Load. You are dropping some voltage across the internal impedance of the battery because your system is drawing current. At 9v it will drop right away. A battery’s voltage drops under load because of the internal resistance of the battery increases. At 11v it is almost going straight down. The greater the load, the larger the voltage drop will be. The internal resistance of the battery causes voltage drops under load. At its 12v mark, you can see there is a tipping point where the voltage goes from relatively constant to plummeting. This is caused by the chemical reaction inside the battery that creates electricity. When the battery is in the system it's closed cell voltage under load. Why does lead acid battery voltage drop under load? When a good battery is put through a load test equal to its rated cca (cold cranking amps) its voltage will drop to around 9.6 to 10.5 volts. 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.
