Battery Self-Discharge
Forklift Battery Self-Discharge . Some of the most frequently asked questions about forklift lead-acid batteries relate to their rate of discharge.. All lead-acid batteries will naturally self-discharge, but how long it takes for the charge to deplete is based on a few variables such as storage temperature, length of storage, sulfating, and whether the battery is exposed to dirt and dust.

The Relationship Between Battery Temperature and Voltage
For example, lithium-ion batteries may experience a drop in voltage as the temperature decreases, while lead-acid batteries may show an increase in voltage under similar temperature conditions. Understanding these differences can help engineers and researchers optimize battery performance in specific applications.

Discharge and Self-Discharge of a Lead–Acid Battery
However, one drawback of this battery type is that the inherent thermodynamics of the battery chemistry causes the battery to self-discharge over time. This model simulates a lead-acid battery at high (1200 A) and low (3 A) discharge rates, and the long-term self discharge behavior with no applied external current (0 A).

Why self-discharge is important in batteries
In addition to the above factors, the self-discharge rate in lead acid batteries is dependent on the battery type and the ambient temperature. AGM and gel-type lead acids have a self-discharge rate of about 4% per month, while less expensive flooded batteries can have self-discharge rates of up to 8% per month.

What happens when a lead acid battery is discharged?
When the lead acid battery is discharging, the active materials of both the positive and negative plates are reacted with sulfuric acid to form lead sulfate. After discharge, the concentration of sulfuric acid in the electrolyte is decreased, and results in the increase of the internal resistance of the battery.
How a lead acid battery self-discharge?
3.3 Battery Self-discharge The lead acid battery will have self-discharge reaction under open circuit condition, in which the lead is reacted with sulfuric acid to form lead sulfate and evolve hydrogen. The reaction is accelerated at higher temperature. The result of self-discharge is the lowering of voltage and capacity loss.
How do thermal events affect lead-acid batteries?
Thermal events in lead-acid batteries during their operation play an important role; they affect not only the reaction rate of ongoing electrochemical reactions, but also the rate of discharge and self-discharge, length of service life and, in critical cases, can even cause a fatal failure of the battery, known as “thermal runaway.”
Can you lower the temperature of a lead-acid battery during discharging?
Thus, under certain circumstances, it is possible to lower the temperature of the lead-acid battery during its discharging.
Does temperature affect battery self-discharge rate?
This loss of water is knownto be a measure of the battery self discharge. In thisstudy, the charging of SLI batteries was examined over arange of operating temperatures as a means forcharacterizing the self-discharge rate as a function ofbattery voltage and temperature. The battery responsewas modeled analytically.
Why does a lead sulfate emit heat at the end of a discharge?
Because of the gradual increase in internal resistance during discharge, this heat will be most pronounced towards the end of the discharge. In the latter case, it is the thermochemical heat generated (or consumed) by the electrochemical reaction at the electrodes during discharge, i.e., the conversion of lead and lead oxide to lead (II) sulfate.
