There is no danger of overcharging the battery in under 5 days.
After a-rest period of 1 or 2 months, charge for 20 hours.
EXCEPTIONAL CHARGE
Immediately after the camera's purchase, or when the batteries have
not been charged for several months, it is very beneficial to
"retrain" them for normal use in the following manner: charge them
for 24 hours. Then let the camera run, empty, for about 10 minutes.
Then charge again for 12 hours. This method is preferable to using
a long consecutive charging period to put batteries left dormant and
inadequately charged back into shape. In serious cases, this
procedure can be repeated until the batteries are perfectly
"re-educated", without any risk of overcharging them.
The only reason for this procedure is to allow the batteries to
"recuperate 'a normal rhythm" if they have been long neglected.
Once this has been achieved. resume charging according to normal
charging times.
A few
hints: To insure maximum battery life, charge them once a
month when not in use.
Do not hesitate to re-charge the battery after a filming session.
There Is no danger of overcharging. Never leave batteries comple-
tely discharged, as this might finally put them out of action.
