Quick Answer: In general, a 12V lead acid battery should measure around 12.6V when fully charged and around 11.8V when discharged. However, various factors like temperature and usage affect these readings.
Lead-acid batteries, like any other batteries, have a different voltage at different stages of charge. For example, a 12V lead acid battery has a 12.73V voltage at 100% charge and an 11.36V voltage at 0% charge. These specific battery
What voltage should a AGM battery be? It should be between 12.9V and 12.15V. If the voltage is lower, then the battery will degrade faster. Try to keep the battery above 50% State of charge (SOC) to maximize lifespan.
Then, the voltage is limited to the peak voltage until the current drops (to 3-5% of the C rate for lead acid batteries). Standard "12V" Lead-acid batteries are six cells; the peak charge voltage is between 13.8 and 14.7V (at 25C, this value is temperature dependent); however prolonged time at this voltage will cause damage.

Essential charging guidelines for a 12V lead acid battery include using an appropriate charger. An ideal charger should provide a voltage of about 14.4 to 14.7 volts during the
When charging a lead-acid battery, hydrogen gas is produced as a byproduct. Electrolysis of water occurs during the charging of a lead-acid battery. The battery''s voltage causes water (H₂O) to break down into hydrogen (H₂) and oxygen (O₂) gases. This reaction is one of the primary contributors to gas production at the battery''s
To charge a lead acid battery, use a DC voltage of 2.30 volts per cell for float charge and 2.45 volts per cell for fast charge. Check the charge levels and monitor the state of charge (SoC).

Just like any other battery type, lead acid batteries have different voltages at various stages of charge. For instance, a 12V sealed lead acid battery has a voltage of 12.89V at 100% charge, while 11.63V indicates it is at 0% charge.
The state of charge (SOC) of a lead acid battery refers to the amount of charge remaining in the battery. The SOC of a lead acid battery can be determined by measuring its voltage using a multimeter or other device. As the battery discharges, its voltage level decreases. Conversely, as the battery is charged, its voltage level increases.
Higher lead acid battery voltages indicate higher states of charge. For instance, 12.6V means a 12V battery is fully charged, while 12.0V means it's around 50% capacity. Temperature affects voltage, too. Cold temperatures increase the voltage while hot temps decrease it. The charts here assume room temperature.
Charts for different lead acid battery voltages follow the same format. Just multiply the voltages by 2 for 24V or 4 for 48V batteries. The only way to get an accurate reading of a lead acid battery's state of charge from voltage is to measure its open circuit voltage.
The voltage of a lead acid battery decreases under load, which means that the voltage will be lower when the battery is powering a device than when it is not. The amount of voltage drop depends on the load and the capacity of the battery. What is the critical low voltage threshold for a lead acid battery?
As a lead acid battery discharges, the voltage decreases linearly. For example, a 12V battery may provide 12.6V when fully charged. After discharging halfway, the voltage will drop to around 12.3V. The rate of discharge impacts the voltage. Faster discharge rates result in lower voltages for a given state of charge.
