Battery Usage Time Information A battery is an expendable supply, so when using it over a long time, the capacity/battery life is shortened. If the battery life is reduced to under half of its initial time, we recommend purchasing a new battery. For long periods of not using the battery, keep the battery after discharging it. This extends the battery life time. 150
