6 FAQs about [How to measure the battery self-discharge power]

How do you measure battery self-discharge?

There’s not one method for measuring self-discharge. The method used depends on the battery chemistry and the level of accuracy required for the measurement. Measuring the open circuit voltage (V oc) is a common way to determine a battery’s state of charge and thereby measure self-discharge over time. But measuring V oc can be challenging.

What happens if a battery has a different self-discharge rate?

Varying self-discharge rates between cells in a battery pack can result in voltage imbalances between the cells and a shorter battery pack life (Zheng et al., 2020). Self-discharge rates vary depending on the cell chemistry, capacity, electrode geometry, electrolyte formulation, impurities, and temperature.

How much does a rechargeable battery self-discharge per month?

But that’s not always the case; specially designed rechargeable nickel metal hydride (NiMH) batteries can have self-discharge rates as low as 0.25% per month (Table 1). There’s not one method for measuring self-discharge. The method used depends on the battery chemistry and the level of accuracy required for the measurement.

How does self-discharge affect the shelf life of batteries?

Self-discharge can significantly limit the shelf life of batteries. The rate of self-discharge can be influenced by the ambient temperature, state of charge of the battery, battery construction, charging current, and other factors. Primary batteries tend to have lower self-discharge rates compared with rechargeable chemistries.

What makes a battery self-discharge?

Self-discharge is an inherent characteristic of batteries. The rate of self-discharge differs among various battery chemistries. In addition, the quality of the materials used and the construction details of the battery can strongly influence the rate of self-discharge.

What factors affect battery self-discharge rate?

Self-discharge rates can vary considerably for different battery chemistries (Table: Wikipedia ). Self-discharge can significantly limit the shelf life of batteries. The rate of self-discharge can be influenced by the ambient temperature, state of charge of the battery, battery construction, charging current, and other factors.
