and Charging of Ni-Cd (Ni-MH) Batteries
Batteries, due to their construction, undergo some wear and tear. The lifetime of a battery also
depends on correct maintenance. Charging and discharging are the most important factors. You
should take notice of the following to maintain the life of the battery as long as possible.
Ni-Cd (Ni-MH) batteries may experience a memory effect. If fully charged batteries are used
several times only for 15 minutes in the handset and then recharged, the capacity of the batteries
will be reduced to 15 minutes due to the memory effect. Therefore you should discharge the
batteries completely, i.e. use them in the handset until “

Then recharge them as described in the manual. After the memory effect has occurred, it is
possible to achieve almost complete capacity of the Ni-Cd (Ni-MH) batteries by charging and
discharging several times one after another.
Ni-Cd (Ni-MH) batteries can also self-discharge. This self-discharge depends on the ambient
temperature. At temperatures under 0°C, the self-discharge will be the lowest. High humidity and
high temperatures support the self-discharge. Also long-term storage will lead to self-discharge. A
dead Ni-Cd (Ni-MH) battery should not be disposed of normally. They contain toxic heavy
cadmium (metal hydride) and therefore should be recycled.
