Does a Battery Lose Voltage As It Discharges? (Why Does)
Why Does Battery Voltage Drop Under Load . Batteries are like people in that they get tired as they work. The chemical energy in the battery is converted to electrical energy, and this process is not 100% efficient. That''s why batteries get hot when you use them for a long time – some of the energy is being lost as heat.

The Ultimate Guide to LiFePO4 Lithium Battery Voltage Chart
3.2 Discharging LiFePO4 Batteries: A. Discharge Voltage Range: LiFePO4 batteries can safely discharge down to 2.5V per cell, but most BMS systems will cut off at around 2.8V to 3.0V per cell to protect the battery. For a 12V battery, this is about 10V to 11V. B. Depth of Discharge (DoD): LiFePO4 batteries can be discharged up to 100% of their capacity without significantly

What Is Deep Discharge and How Does It Affect Batteries?
Part 2. What happens during deep discharge? When a battery undergoes deep discharge, several critical changes occur: Voltage Drop: As the battery discharges, its voltage decreases. Each battery type has a specific cut-off voltage where it ceases to function effectively. For example, lead-acid batteries typically should be discharged at 10.5 volts.

What is discharge voltage?

What happens when a battery discharges?
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. The voltage also drops because of internal resistance within the battery itself.
Should a battery be discharged to a lower voltage?
At a very high current flowing for only a very short time, it is not only' safe, but advisable to allow a battery to discharge to a lower voltage, the increased drop being due to the rapid dilution of the acid in the plates. The cell voltage will rise somewhat every time the discharge is stopped.
What affects the change of battery discharge voltage?
The change of the battery discharge voltage is related to the discharge system, that is, the change of the discharge curve is also affected by the discharge system, including: discharge current, discharge temperature, discharge termination voltage; intermittent or continuous discharge.
What is the discharge characteristic curve of a battery?
The working voltage of the battery is used as the ordinate, discharge time, or capacity, or state of charge (SOC), or discharge depth (DOD) as the abscissa, and the curve drawn is called the discharge curve. To understand the discharge characteristic curve of a battery, we first need to understand the voltage of the battery in principle.
