•When you attempt to charge a battery pack which has never been charged before, the actual charging amount stays less than 80% of nominal capacity*.

*Average capacity when a single cell is charged at 0.1C for 16 hours and discharged at 0.2C.

•Charging of the nickel metal hydride battery pack when an ambient temperature or the temperature of the battery pack itself is more than 30˚C (50˚F), charging time will be longer and charge amount will be less than the case of charging with ambient or the battery pack temperature between 10˚C and 30˚C (50˚F and 86˚F).

When charging with temperature of 40˚C (104˚F), charging finishes with 80% of full capacity. In this case, recharging is possible with temperature of 30˚C (50˚F) or less. Note that recharging is only possible for battery packs whose remaining capacity is 90% or less to prevent excessive recharging.

Lithium-ion battery packs are free from memory effect. There is no need to discharge them fully before recharging.

If the usable time of a battery pack becomes very short, it is time to replace it with a new one.

Battery pack charge indicators at high or low temperatures

The battery pack cannot be charged when it is too hot or too cold. If a charge indicator at the top of the battery charger (figure below) flashes orange, it means that the battery pack temperature is above or below a given standard and that the charger is waiting for the battery pack to return to a temperature at which charging is possible. If the battery pack does not return to the standard temperature within a given time, an error arises and charging is not carried out.
