AFAIK all the Sonicare models use lithium-ion batteries. Even after (I think) 5 years mine's still good for around 2 weeks of use.
The cheaper Oral-B models use NiMH batteries, and they don't make clear in the product info which models use which, you really have to do some research to figure this out. Family members who have the Oral-B NiMH models have found they can no longer hold a charge for more than a day or two after a few years of use.
