After you receive your new batteries it is important to charge them correctly. To do this open the battery compartment on the handset or handsets and look at the way the existing batteries are fitted. This is important as you must fit the new batteries the same way round.
This is also referred to as observing the polarity. Then remove the old batteries or battery and fit the new ones. Then place the handset on the base unit or satellite charging unit and leave to charge for 24 hours. You can make emergency calls after a few minutes. If you have multiple handsets you can leave one in general use while you charge the other handsets.
Then after the charge period you can use your cordless phone normally. It will take 3 to 4 charge cycles for the new cells to reach maximum capacity. For more on this and other relevant subjects please see the information section above. More interesting reading on telecommunications.
