As I mentioned before, one of the first things I did with my Hackbook was to downgrade the BIOS so I could use 3rd party batteries. Well, I’m happy to say the battery I ordered from MyDigitalDiscounts works great with my laptop. I haven’t tested the duration yet, but plan to on an upcoming 6 hour flight. Hopefully I’ll get to watch at least three films before the juice dies -supposedly the 8-cell battery can provide up to 10.5 hours (YMMV). I’ll report back in another week or so with some real world numbers and I can’t stand reading benchmarks…

One thing to note on this battery – it does give you laptop a high heel effect. The battery is so large that it rakes the entire unit. It actually makes it more comfortable to type on – and the battery has anti-skid pads on it so it should stay put on your desk or tray table. I am a little concerned because the screen won’t tilt as far back as it does with the stock battery. On a desk or lap, that’s no problem – I am a bit wary about the tray table though. We’ll see. I can always prop up the front on a book.
