Using Your Battery Packs Effectively
Immediately After Purchase
• Newly purchased battery packs have not been charged, so charge completely
before using.
• When charging brand new battery packs, charge until charge indicator lights,
and disconnect. Then reconnect and charge a second time.
General Use
Battery packs can be charged when the ambient temperature is between
0°C—40°C. Best results are achieved between 10°C—30°C.
After the battery pack has been fully charged, do not continue to try to recharge
it. Repeatedly recharging a fully charged battery pack can cause it to become
overcharged.
Repeatedly recharging a battery pack before it is fully discharged will cause its
electrical storage capacity to decrease (charge memory). In such cases,
discharge the battery pack completely by waiting until the camera’s
OPERATE/CAUTiON indicator goes out, or by using the battery video light until it
grows dim. The indicator will go out about 10 minutes after it begins to flash
(unless video light is attached), and the battery pack can then be removed.
When using the battery pack with the battery video light, be sure to disconnect
the battery pack when the light begins to grow dim. Continuing to use the battery
pack in such a situation may cause it to be discharged below specified-level.
Immediately after use, the battery pack will be quite hot and it is best not to
recharge it at this time. Make sure that the battery pack has cooled off before
recharging.
When a battery pack has been discharged below specified level, you may be
unable to recharge it completely (the battery pack will not recharge fully even
though the charge indicator lights). In such a case, charge and discharge the
battery pack repeatedly (2—3 times) until it is recharged properly.
Storage
When the battery pack is connected to the camera, it will continue to discharge
even when the power is turned off, and this may cause it to become discharged
below specified level. Disconnect the battery pack from the camera when
storing.
When storing the batteiy pack for a long period of time, choose a cool,
chemically stable location. Allow it to discharge completely by connecting it to
the camera and waiting until the OPERATE/CAUTI on indicator goes out (about 10
minutes after it begins to flash).
If the battery pack has been stored for three months or longer, a single
recharging will not be sufficient to restore it to full operability. In such a case,
completely recharge and completely discharge the battery pack 2—5 times.
This will restore it to its original capacity.
Teritiinology
Overcharging and discharging below specified level will cause the battery pack
to function less effectively, and will shorten its life.
Overcharging
Charging a battery pack after it has already been fully charged.
Discharging below specified level
Continuing to discharge a battery pack after its voltage level has fallen below a
specified level (5.0 V for the nickel-cadmium batteries used by Canon 8mm
video cameras).
Charge memorV
When a nickel-cadmium battery is discharged only partially (not long enough for
the charge to cut off automatically), and then recharged and used again, the
continuous recording time decreases. The battery pack will be temporarily
incapable of discharging to final voltage level.
