Charging and Discharging

3 Important Battery Information

Note: use only rechargable AAA NiMh battery of typical 800 mAh, 1.2 V. Never use a battery which is damaged or worn out.

Heat or cold reduces the performance and service life of the batteries. It is possible that a handset with hot or cold batteries can be temporarily out of operation even if the batteries are fully charged.

Used batteries should be disposed of in accordance with local authority regulations. Hand them in for recycling!

Do not throw batteries in a fire.

The batteries can be charged and discharged hundreds of times, but sooner or later they will be worn out. If the operating time (i.e. talk and standby time) is significantly shorter than usual, then it is time to replace the batteries.

To maintain optimum operating time, the batteries should be discharged from time to time by not placing the handset in the charger but leaving it switched on until it switches itself off. Only use this method to discharge the batteries.

Extreme temperatures influence the charging capability of the batteries.
