More Laptop Battery Life Stuff

I have a Toshiba A200-1V0 Laptop as do a lot of other people in the UK due to it's price vs. features.

It's a great little machine, but the supplied battery life leaves something to be desired.

On the front of the box when I bought it there was an offer to get a second battery sent out if I registered with Toshiba - I did and they sent me the battery.

Turns out that there are 3 different batteries that are available for the Toshiba Equium A200-1V0:

The supplied 3 cell one lasting about 45 minutes to 1h 15 minutes depending on usage
A 6 cell option, which lasts for around 2-3 hours depending on usage
A 9 cell option which I've yet to try.

Toshiba sent me a 6 cell battery for registering with them which helped me out no end on my journey to work (1h 15 mins on the train each way). With the original battery I had to charge the machine each end, at home and at work, meaning that I always had to carry the power supply plug with me.

With the free6 cell batter I just had to charge the machine once a day i.e. at home over night ready for the next morning meaning I could leave the supply plug behind.

BUT I want to go further and actually get the 9 cell option now I've seen how much an improvement the 6 cell is over the 3.

I looked on the Toshiba website (http://uk.computers.toshiba-europe.com) but there was no information there, so I phoned the number shown: 0870 444 8944 to try and order it as a spare part. Still no luck as I phoned on a Saturday and Toshiba use a 3rd party who don't work weekends to deal with repairs and spares: http://www.topazsupport.co.uk - 0844 800 2835

So I visited them and they only show a 6 cell replacement battery: http://www.topazsupport.co.uk/product248.html which seemed a bit odd.

I'll call them on Monday to find out exactly what the situation is but it doesn't seem that promising
