NICKEL METAL HYDRIDE BATTERIES - CONTINUED
Features
These batteries have similar discharge characteris-
tics to those of Ni-Cd batteries.
Nickel-metal hydride batteries have approximately
double the capacity compared with Panasonic’s
standard Ni-Cd batteries.
Like Ni-Cd batteries, nickel-metal hydride batteries
can be repeatedly charged and discharged for about
500 cycles. (example: IEC charge and discharge
conditions)
Nickel-metal hydride batteries can be rapidly
charged in about an hour using a specially designed
charger.
Since the internal resistance of nickel-metal hydride
batteries is low, continuous high-rate discharge up to
3CmA is possible, similar to Ni-Cd batteries.
Similarity with Ni-Cd batteries
Double the energy density of conventional
batteries
Cycle life equivalent to 500 charge and
discharge cycles
Rapid charge in approx. 1 hour
Excellent discharge characteristics

Five Main Characteristics
As with Ni-Cd batteries, nickel-metal hydride batteries
have five main characteristics: charge, discharge,
storage life, cycle life and safety.
1)
Like Ni-Cd batteries, the charge characteristics of nickel-
metal hydride batteries are affected by current, time and
temperature. The battery voltage rises when the charge
current is increased or when the temperature is low.
The charge efficiency differs depending on the current,
time, temperature and other factors.
Nickel-metal hydride batteries should be charged at a
temperature ranging from 0 C to 40 C using a constant
current of 1It or less. The charge efficiency is particularly
good at a temperature of 10 C to 30 C. Repeated
charge at high or low temperatures causes the battery
performance to deteriorate. Furthermore, repeated
overcharge should be avoided since it will downgrade
the battery performance.
Refer to the section on recommended charge methods
for details on how to charge the batteries.
