      I have the cheapest oral-b (bought for under 20 euros about a decade ago) and it uses AA-batteries, a pair of rechargeable ikea 1900mah batteries last for about 100 cumulative minutes of usage.

      Yup, you need to send it back to them but for a few quid (or included if you have their replacement head subscription) they will change the battery for you.
