Charging and Battery Storage Notes

Keep the following in mind for proper charging, maintenance, and
storage of the battery.
• Only recharge the battery at room temperature, approximately
50°F to 104°F (10°C to 40°C). Charging at a high temperature
will increase the time it takes to charge the battery.
• The battery will discharge during storage. Always check the
battery charge before using the BR-1.
• Charge a stored battery every 7 days. Allowing a battery to
become discharged can reduce the overall performance of the
battery and charge efficiency.
• The charger may become somewhat heated while charging the
BR-1.

Installing the Battery

The rechargeable battery can be charged using either the power port
(see "Charging the Battery" on page 2-1) or the optional charger.
