Dell 9-cell Laptop Battery

Just a quick question about whether it is worth th £70 extra and if it really incereases battery life by a decent amount?

Any advice is appriciated.


Battery life is increased pretty much linearly (50% longer than a 6-cell, three times as long as a 3-cell). Worth extra £70? Probably not, depends largely on how you intend to use laptop but it seems quite a premium - if it was a case of getting a 9-cell + an extra spare 3-cell or 6-cell for the £70 I'd have said yes, but on its own probably not (assuming thats the premium on a 6-cell?)

Also worth considering a 9-cell normally sticks out a bit at the back making a laptop a bit more awkward to fit in a sleeve/bag and a bit heavier...

I got a 9cell from ebay for £40. It was identical to the one that came with my laptop.
I get about 5-6hours out of it.
