CHARGE lamp to a wall outlet (wall socket) 2 Power cord (Mains lead) , 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. 12 Charging time Nickel-Metal Hydride Charging time battery NH-AA-DA × 2 (supplied) Approx. 6 hours 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.
