play can be used as a guide for recharging and replacing the battery.

follows depending on the operating con-
ditions.

• Usable time decreases quickly as the
temperature drops. Battery performance
will be recovered when the battery
warms up again.
Battery life
• Batteries are consumable. The battery's usable time will be shortened with
repeated charging and discharging. The battery should be replaced when it
can only be used for about half as long as a new battery.
• Leaving the battery unused in a fully charged state for an extended period of
time shortens battery life.
• The battery will naturally discharge gradually when left unused. It will discharge
approximately 10% to 20% in one month, and 50% in six months. It may
become unusable if left unused for a year or more.
