A few weeks ago I bought an extended six-cell battery for my HP2133 Mini-Note. I had originally thought that the three-cell battery would be enough for me, but I was spectacularly wrong. As I’ve just started my PhD, I am finding that I have a lot of two-hour seminar sessions that I have to complete, and the three-cell battery was battling to get to an hour or so, tops, when I ran it on the ‘high-performance’ settings.
And running the HP2133 Mini-Note on low-power use is not recommended if you need to do anything substantive, although it’s fine for tapping out a few notes.
With the extended battery, and on low-power mode, I’m easily getting 3 or more hours of practical use out of the notebook. The battery is very good, although I don’t like the way that the higher battery makes the machine sit up – it’s far less ergonomic if you’re typing on a flat surface (which is what you should be aiming for). With the six-cell battery, and if you keep the three-cell charged up and carried around with you, you’ll get through a day interspersed with meetings and presentations and plane flights very easily in my view.
If you’ve got the mini-note, the extended battery is a must-have.
