It doesn't mention the new low discharge rate "hybrid" NiMH batteries.
These might be a better choice for your phone because their
self-discharge rate is lower. If you find that your batteries have gone
flat even though you haven't used the phone then these new batteries
might be a good choice for you. You can recognise them because they are
usually sold fully charged.

It depends if the phone is kept on the cradle most of the time. If it is,
the batteries will be on trickle charge so the self-discharge won't matter.
If you keep the phone switched on but off the cradle, the batteries will
probably go flat in a week or two anyway. It's only if you turn the phone
off for months that the self-discharge becomes an issue.

Personally I'd buy a cheap'n'nasty pair of batteries for a phone, as you
can't be sure the charger is any good. Unless you talk for hours and hours
on end without putting the phone back on the cradle, the batteries are
probably going to be sufficient - higher capacity is better. Until the
charger kills them, at which point you just have to buy some new ones.
