Switching off mains supply and my cordless phone battery advice for all makes of phone:
If you are switching off the mains supply connected to your phone base unit, perhaps while you go on holiday, it is advisable to also remove the rechargeable phone batteries from the handset.
This is because the handset will continue to use or flatten the phone batteries when the mains supply is disconnected.
It does this by repeatedly trying to re-establish contact with the now disconnected base unit.
Also if this continues until one or more of the cells go flat then the first cell at zero volts will be charged in reverse polarity by the other partly charged cells causing permanent failure. For more advise please see our Home page and Guides page.
Here you can find advice on disposal or recycling of your old battery.
Please make sure that you buy the correct rechargeable batteries for you phone. Do not use alkaline batteries in the handset if you are going to place it on the base unit to charge. This is because alkaline batteries are not rechargeable. If you needed to use your phone and the batteries in the handset were faulty then the handset will work with alkaline batteries for an emergency situation. Just remember not to place the handset on the base unit.
There are many makes of batteries available on many shopping sites some of them are good and many are not. We provide a 3 year warranty against manufacture type failure. This does nut include wearing the batteries out which will happen over approximately 1000 cycles. If a company is offering higher capacity cells then these will not charge properly. You can see the operating range in more information on our product pages.
