Old batteries failing I wondered if was worth replacing the batteries or the complete shaver but having paid quite a lot for the shaver I decided to replace the batteries.
The batteries arrived as expected, all I needed was to fit them, following the guide on U tube I started out. It was a bit fiddly tiny parts all placed in order to be refitted, the top came off to find the second part was a different model to u tube, then to find a different video of my model. The rubber holding it together proved a little difficult to remove this done the batteries slipped in easily.
Charged the batteries have lasted six day before the charging came on, quite pleased with that.
