As a battery expert with extensive experience in the field of energy storage solutions, I'm often asked about the specifics of battery voltages, especially when it comes to deep cycle batteries. Deep cycle batteries are designed to provide a steady supply of power over a longer period, making them ideal for applications such as RVs, marine systems, and renewable energy systems.
Understanding the voltage of a fully charged 12-volt deep cycle battery is crucial for maintaining the health and longevity of the battery. The voltage of a battery is a measure of its electrical potential, and it's one of the key indicators of its state of charge.
A standard 12-volt deep cycle battery is actually composed of six individual cells, each with a nominal voltage of 2.1 volts. When these cells are connected in series, they sum up to provide the total voltage of 12 volts.
When a 12-volt deep cycle battery is fully charged, the voltage across each cell should be between 2.12 to 2.15 volts, which translates to a total voltage of approximately 12.7 volts for the entire battery. It's important to note that this voltage is slightly higher than the nominal 12 volts because the battery is in a state of overcharge, which is normal and expected when the battery is fully charged.
As the battery discharges, the voltage per cell (VPC) will decrease. At 50% state of charge, the voltage per cell typically reads around 2.03 volts, and as the battery approaches a fully discharged state, the voltage per cell will drop to 1.75 volts or lower.
In addition to voltage, another method to determine the state of charge is by measuring the specific gravity of the electrolyte in each cell. For a fully charged cell, the specific gravity is approximately 1.265. As the battery discharges, the specific gravity will decrease, reaching 1.13 or less when the cell is completely discharged.
It's worth mentioning that regular monitoring of both voltage and specific gravity is essential for the proper care and maintenance of deep cycle batteries. Keeping track of these readings can help prevent overcharging or deep discharging, both of which can significantly reduce the lifespan of the battery.
In conclusion, a fully charged 12-volt deep cycle battery should read a total voltage of around 12.7 volts, with each cell contributing between 2.12 to 2.15 volts. Monitoring this voltage, along with the specific gravity of the electrolyte, is key to ensuring the optimal performance and longevity of your deep cycle battery.

Voltage on a fully charged battery will read 2.12 to 2.15 volts per cell, or 12.7 volts for a 12 volt battery. At 50% the reading will be 2.03 VPC (Volts Per Cell), and at 0% will be 1.75 VPC or less. Specific gravity will be about 1.265 for a fully charged cell, and 1.13 or less for a totally discharged cell.
