DC battery single cell voltage is high

The nominal voltage of lithium-ion is 3.60V/cell. Some cell manufacturers mark their Li-ion as 3.70V/cell or higher. This offers a marketing advantage because the higher voltage boosts the watt-hours on paper (voltage multiplied by current equals watts). The 3.70V/cell rating also creates unfamiliar references of 11.1V and 14.8V when connecting ...

What is a single cell voltage?

Angel Kirchev, in Electrochemical Energy Storage for Renewable Sources and Grid Balancing, 2015 The single cell voltage (denoted as Ucell) is the electric potential difference between the positive and the negative battery terminals.

What is battery voltage V?

The electrical potential between the anode and the cathode in the batteries is called the battery voltage. Different battery cell generate different voltages, the higher the better.

What is the nominal voltage of a lead-acid battery?

By convention, the cell voltage of lead–acid batteries is 2 V; therefore, the nominal battery voltage is always a multiple of 2 V. The voltage of the vehicle system, however, is set somewhat higher than the nominal voltage to operate the battery, given the overvoltage required to recharge lead–acid batteries.

What is the nominal voltage of a battery?

Here are the nominal voltages of the most common batteries in brief. 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.
