(Why Does) As a battery discharges, the voltage it produces decreases. However, the amount of voltage lost during discharge depends on the type of battery and how it is used. For example, lead-acid batteries typically lose about 2% of their voltage per cell per hour when discharged at a constant rate. As a battery discharges, its voltage drops.
When removing the load after discharge, the voltage of a healthy battery gradually recovers and rises towards the nominal voltage. Differences in the affinity of metals in the electrodes produce this voltage potential even when the battery is empty. A parasitic load or high self-discharge prevents voltage recovery.
Keep the discharge power unchanged, because the voltage of the battery continues to drop during the discharge process, so the current in the constant power discharge continues to rise. Due to the constant power discharge, the time coordinate axis is easily converted into the energy (the product of power and time) coordinate axis.
When a battery is discharging, the voltage across its terminals will decrease for a number of reasons. Firstly, as the battery discharges, the concentration of reactants in the electrodes will decrease and this will lead to a decrease in the potential difference between them.
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.
When the voltage of a battery gets too low, it needs to be replaced. As any battery ages, it will slowly lose its ability to hold a charge. This is due to a number of factors, including corrosion, electrolyte evaporation, and plate shedding. As the battery’s voltage drops, so does its capacity to power your devices.
