• Batteries generate power using a chemical reaction and as a result have a limited lifetime. Even
when in storage and not used for long periods, battery capacity deteriorates with the passage of
time. This may result in the operating time of the battery shortening despite having been charged
correctly. In this event, a new battery is required.
