6 cell vs 12 cell dell battery

[Jacquelim]

I bought a 6 cell replacement battery from RAVPower for my hp DV2000, after full charging, the normal use is 2 hours. I also want a longer battery using time. Is the 12 cell battery better than 6 cell battery? Does it fit the laptop well?

the only battery for dv 2000 i saw there are for hp but yes a 12 cell will give you more power and last longer
