Analogue or digital ?

[scooby1]

I am asking for advice please and would very much appreciate it anyone could advise me on what I'm sure is a very simple question but because of my age I am struggling a bit. We own and live in a private household with just one telephone line and at the moment we have a Gigaset telephone base station and 2 subsidiary phones in 2 other rooms. We need to update the phone system because although we have renewed the AAA re-chargeable batteries in all 3 handsets they all keep losing their charge during any lengthy conversation.
We rather like the PANASONIC KX-TGU433EB system https://www.currys.co.uk/products/p...MIwpD-8-OIkgMVvZZQBh1nzQ_DEAQYByABEgKnlfD_BwE
but are in the dark about whether we should be buying a system that plugs into our router as well as the BT wall socket. We have a splitter socket mounted on the wall that was installed by a BT chap which plugs directly into our main BT socket and which both our telephone system and our EE Smart router are plugged into.
We live in a very small village which in fact has the BT exchange in it, we are about 300 metres from the exchange. My question is, should we buy a system that will work out of a router as well as a normal BT plug if all lines are eventually changed to digital ? Apologies if I have been typing nonsense but I really could do with some help.

The change, will be to fibre, and the router will have a phone socket in it, into which to plug your phone. Any phone, or phone system can be plugged in, so get what ever phones you like now - they will work.

Your AAA cells should keep the phones in use, going for hours - Are they decent quality cells? Are you dropping them back on the charger base, after each use?
