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.
≥
The number of flashes fired by the unit may also be sharply
reduced if the
+
and
-
electrodes of the batteries are
exposed to oils from the skin or other forms of dirt. Before
installing the batteries, wipe the
+
and
-
electrodes carefully
using a soft, dry cloth.
If electrolytes should leak from the batteries, wipe away all traces
of the electrolyte in the battery compartment, and then insert
fresh batteries or fully charged nickel metal hydride batteries.
If you should get electrolyte on your hands or clothes, rinse it off
thoroughly with water. If you should get electrolyte in your eyes,
you risk losing your sight. In such a case, do not rub your eyes
but immediately wash them with clean water, and then seek
medical advice.
≥
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.
