1. What is Charge Retention? Charge retention refers to a battery’s ability to retain its stored electrical energy over time when not in use. This is inversely related to the self-discharge rate, which measures the rate at which a battery loses capacity on its own, without any load. For LiPO batteries, charge retention is one of their strengths […]
