Canon EOS 300 D - Manual (Page 19)

Recharging the Battery
O © Do not recharge any battery pack other than Battery Pack BP-511 or
BP-512.
® If the battery is left in the camera for a prolonged period without the
camera being used, a low electrical current may be discharged
excessively and the battery’s service life may be affected.
When not using the camera, remove the battery and attach the
protective cover to prevent shorting. Before using the camera again, be
sure to recharge the battery.
After the red lamp lights, continue to recharge the battery for an
hour to attain a full charge.
© After recharging the battery, detach it and unplug the power cord from
the power outlet.
O The time required to recharge the battery depends on the ambient
temperature and battery’s power level.
O The battery pack can operate in temperatures from 0°C to 40°C (32°F to
104°F), however for full operating performance, use between 10°C
(50°F) and 30°C (86°F) is recommended. In cold locations such as ski
areas, battery performance is temporarily decreased and operating time
may be reduced.
Q If operating time is sharply reduced even after charging normally, the
battery pack may have exceeded its useful life. Replace it with a new
battery pack.
