There's a chance that the Vox uses a very generic battery that other 7" tablets use. However, with pretty much all products I bought in the last few years I never had to replace a lithium battery. It might be quality brands like Sandisk, HP and Toshiba just use better quality of lithium batteries unlike certain companies who pose their cheap garbage as quality (I'm referring to many big companies that sell stuff by just using their names to sell products). My Father is using a 8 year Nokia phone and it practically has as good battery life as the day he bought it.

Edit: That article seem very bias to me.
