Best Battery for cordless phone

Jake'sGran

We are low phone users but there is just my oldest friend that I speak to for about an hour. Lately the phone goes off after about half an hour and she said I need to buy the best quality battery.
What do I ask for and are they expensive (not that this matters). My OH has some weird habits when it comes to batteries and I wonder if he uses old ones sometimes when replacing them - crazy! While we are at it, which do you think is the best cordless phone?.

It depends on the make and model of phone you have.

Cordless phones usually use NiMH batteries these days but the type varies. Many are AA or AAA but some have special battery packs. You'll need to take the old one(s) out to check.

Then go onto ebay. £5 or so should do it.

After I posted I found an article by Which and top of the list of the Panasonic Lithium @ £6.99. They gave it 100% for performance.
But further down the list they say Morrisons's own are good at £1.69. These are both AA

My Binatone E3300 phone's battery is dieing at the moment, I can't make calls but can receive calls. The battery is approx £5, I have seen some advertised on ebay cheaper but are companies in China, has anyone bought direct from China? The ones from English companies are going to have been manufactured in China anyway, so I am thinking I might as well save some money.
