Dell notebook battery maintenance FAQ

1. Dell notebook battery on the issue of control circuit

As far as I know, the dell laptop battery is not purducted bu dell, it is producted with barebones and OEM. Dell's standard battery must have a control circuit, About 18650 public version of the design, just have no so many tricks like IBM laptop battery.But it’s safe when using.
