
• If the 12vDC external battery is disconnected while working, the power source will
automatically switch to the BT-53Q rechargeable battery.
• Be sure to charge the battery within the charging temperature range (10 to 35°C).
• Do not perform charging with others except the AC/DC converter AD-13.
• For l.onger battery life, conform to the suggested charging time to the extent possible.
• The battery source will discharge when stored and should be checked before using with
instrument.
• Do not recharge the battery when fully charged. Doing so will lower battery performance.
• For long-term storage, the battery should be charged at least once per 3 to 6 months and store
in a place at 30°C or below. If you allow the battery to become completely discharged, it will
have an effect on future charging.
• 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.
