Rechargeable nickel metal hydride
batteries
Nickel metal hydride batteries can be made ready
for use by recharging them using a dedicated
charger. However, mishandling may cause
electrolyte leakage, heat generation, the ignition
of flames and even rupturing of the batteries
themselves. Heed the following precautions.
Nickel metal hydride batteries have a specific
service life. As they are increasingly used or as
time goes by, their capacity will diminish gradually.
When the length of time during which the unit can
be used has dropped drastically, the batteries
may have reached the end of their service life.
Obtain fresh batteries.
≥ The length of the service life of batteries differs
depending on their storage method, operating
conditions and the environment in which they
are used.
∫
When the unit is not going to be used for a
prolonged period
≥ If the batteries are left inside the unit, a faint
current will flow continuously, even when the
unit’s power is off, gradually discharging the
batteries. If they are left like this, they may
overdischarge and may become unusable even
when recharged.
≥ When storing the batteries for a prolonged
period, it is recommended that they be charged
once a year and that after their remaining
charge has been used up, they be removed
from the unit and stored again.

(number of full flashes in MANUAL mode at
intervals of 30 seconds)
Photo taking conditions
≥ Temperature: 23 °C
Flash interval
≥ The number of flashes and flash interval differ
slightly depending on the storage status of the
batteries and the operating conditions.
≥ It may not be possible to properly recharge
batteries with dirty + and - electrodes. Use
a soft, dry cloth to carefully wipe the + and -
electrodes as well as the terminal areas of the
charger.
≥ Either when they are purchased or when they
have not been used for a prolonged period,
nickel metal hydride batteries may not have a
sufficient charge. This is due to their
characteristics and is not indicative of trouble.
Their regular performance will be restored
after they have been charged a number of
times.
≥ It is recommended that the batteries be
recharged only after their existing charge has
been used up. If they are repeatedly charged
without their existing charge first having been
used up, it may be difficult for them to sustain
their capacity. (A phenomenon referred to as
the memory effect.)
≥ If the memory effect has occurred, use up the
existing charge in the batteries until the unit
cannot fire and then recharge them fully a
number of times. This will restore their
capacity.
≥ When nickel metal hydride batteries are not
being used, their capacity will diminish due to
the effects of natural discharging.
≥ Do not continuously charge nickel metal
hydride batteries which already have a
charge.
≥ Do not remove their external jackets or
damage them in any way.
≥ Read the instructions accompanying the
charger used when recharging the batteries.
