According to a common industry standard, a BESS is considered to have reached the end of its service life when its actual charging capacity.

Charged batteries lose energy over time, even when they are not used. The self-discharge rate measures the percentage of energy lost within a certain period (usually 1 month).

This figure refers to the voltage a battery can be charged and discharged with safely. The voltage range of an accumulator largely depends on the storage technology.

The optimum operating temperature for most BESS is around 20 degrees Celsius. However, they tolerate temperatures between 5 and 30 degrees Celsius. Some technologies are more tolerant of temperature variations than others.
