Battery Information
After your Panasonic batteries are fully charged:
• Battery life may vary depending on usage conditions, such as:
– when viewing the Caller ID Caller List, and
– ambient temperature.
• Clean the handset and the base unit charge contacts with a soft, dry cloth
once a month. Clean more often if the unit is subject to grease, dust or
high humidity. Otherwise the batteries may not charge properly.
• If the batteries are fully charged, you do not have to place the handset on the
base unit until "Û" flashes. This will maximise the battery life.
• The batteries cannot be overcharged.
• Nickel metal hydride (Ni-MH) rechargeable batteries (AA size) are available.
When you replace the batteries, you must program the battery type selection
(see page 00).
Important Notice concerning the Correct Use and
Charging of Ni-MH Batteries
Batteries, due to their construction, undergo some wear and tear. The lifetime of a
battery also depends on the 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-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 "Û" on the display starts flashing.
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-MH batteries
by charging and discharging several times one after another.
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-MH battery should not be
disposed of normally. They contain toxic heavy metal hydride and therefore
should be recycled.
