FAQs about Inverter battery self-discharge current
What is battery self discharge rate?
The rate at which battery capacity is lost during storage is called the self-discharge rate. The battery self discharge rate, also known as the charge retention capacity, refers to the ability of the battery to maintain the stored capacity under certain conditions when the battery is in an open circuit state.
