Connect the battery charger to 
a wall outlet (wall socket) using 
the power cord (mains lead).
Charging starts, and the CHARGE lamp 
lights. When the CHARGE lamp goes out, 
charging is finished.
For details on the battery charger, see page 
121.
To remove the batteries
Press the - end of the battery down in order 
to raise the + end, then remove the battery.
When charging is finished, disconnect the 
power cord (mains lead) from the wall outlet 
(wall socket), and remove the Nickel-Metal 
Hydride batteries from the battery charger.
Charging time
This represents the time required to charge fully 
depleted Nickel-Metal Hydride batteries using 
the supplied battery charger in an environment 
where the ambient temperature is 25°C (77°F).
Charging is complete in approximately six 
hours. The CHARGE lamp may remain lit 
longer than six hours, but this is not a 
malfunction.
If you use the battery charger supplied with the 
STAMINA “Quick charge” kit (not supplied), 
the batteries will charge faster.
Charging time
When charging two Nickel-Metal Hydride 
batteries: Approximately 2 hours 30 minutes
When charging four Nickel-Metal Hydride 
batteries: Approximately 5 hours
Notes on the Nickel-Metal 
Hydride batteries
• At the time of purchase, or when the 
Nickel-Metal Hydride batteries have not 
been used for a long time, they may not 
be fully charged. This is typical of this 
type of battery, and is not a malfunction. 
If this happens, repeatedly using up the 
battery fully, and then recharging it, 
should correct the problem.
If the poles of the Nickel-Metal Hydride 
batteries are dirty, the batteries may not be 
charged properly. Occasionally clean the poles 
of the batteries and the terminals of the charger 
by wiping them with a dry cloth.
When transporting the Nickel-Metal Hydride 
batteries, be sure to use the battery case 
(supplied). If the +/- metal terminals are 
shorted, there is a possibility of danger from 
excessive heat or fire.
Even when Nickel-Metal Hydride batteries are 
not being used they lose their charge naturally 
over time. It is recommended that you recharge 
the batteries just before using them.
If you recharge Nickel-Metal Hydride batteries 
before fully using up the existing charge, the 
so-called memory effect* can occur, and the 
low battery warning will be triggered sooner 
than expected. Charging the battery after fully 
depleting the existing charge should correct the 
problem.
*
The “memory effect” – the situation in which a 
battery temporarily accepts a less than full 
charge.
