As a battery discharges, its voltage drops. This is because the chemical reaction that produces the electricity is not 100% efficient, so some of the energy is lost as heat.

View moreOne of the main reasons that battery voltage dropping under load is because the current passing through the battery causes resistance. This resistance creates heat, which in turn reduces the battery’s ability to deliver power. Additionally, as a battery discharges, its internal resistance increases, which also contributes to a voltage drop.
So, the voltage drop is real — the measured voltage is what your load gets. The more current it draws from the battery, the lower is voltage it gets. When the battery is open you are measuring an open cell voltage. When the battery is in the system it's closed cell voltage under load.
When the battery is open you are measuring an open cell voltage. When the battery is in the system it's closed cell voltage under load. You are dropping some voltage across the internal impedance of the battery because your system is drawing current when the measurement is being made (so at the terminals the voltage is indeed lower).
Discharge Voltage – the amount of battery voltage available at any given point while the battery is discharging. The voltage of a battery gradually decreases as it discharges. The rate of this decrease depends on the device it is powering and the battery chemistry.
The amount of voltage drop will depend on how much current the battery is supplying. A 12 volts battery should read around 11 volts when under load. Keep in mind that this is just a general guideline and may not be accurate for all situations. If you are unsure of what the voltage should be, it is best to consult with a professional.
Internal Resistance: As a battery ages, its internal resistance increases, which can affect the voltage under load. This is one reason why older batteries tend to deliver lower voltages than newer ones. Part 3. Various types of voltage
