9-cell battery for Aspire One? What's the life like?

I'm referring to this battery.

My 6-cell is starting to barely give me 4 hours after I accidentally pushed it too far a couple times, and I was searching for a replacement and found these new "9-cell" batteries. Do they really provide the jump in battery life that 6-cells provides over 3-cells? Any experience with these? Thanks for any help.

 

Well, it's 7200mAh. So compare that to the mAh it states on your battery and from there draw a direct parallel to useable battery time.
They don't provide the same jump as from 3-to-6, assuming that the 3-cell is in fact only half that of the 6-cell (i.e. a doubling). But if they're "straigt", it should provide another 50 percent (half of what the 6-cell provides).

I hope that sort of makes sense.

Edit: Found out the 6-cell is 5200mAh. So it's _almost_ 1.5 times as much time you will get by using a 9-cell.

 

6 hours or so. Give or take 20 minutes.

 

That makes perfect sense. I was just wondering if this was legit and if anyone had any experience with 9-cell batteries.

 

What? I got 5 easy on my new 6-cell.

 

Yeah, I think he's calculating from what you get now. But if you got 5 "easy" on a 6-cell you should be able to get 7-7.5 hours (not necessarily "easy" as that would mean the 9-cell should be slightly higher in amperage - or milliamperage as it were)

 

Does anyone know a good free utility to test the wear of my current battery so I know if I need a new one?

 

I have a good 6 hours if I don't run too much background service.

When I start to run database (oracle XE, and others background stuff), then it drop quite a lot, I get around 4-5 hours

 

Using the 9-cell?

 

yes, with the 6 cell it's about 3 hours.

I use it to test some query, and sometimes it spin the disk a lot, I guess that where the lost went.

 

I get 6-7 hours with the standard 6 cell battery. My power draw is about 8W idle and up to 20W fully loaded.
7.2Ah*11.1v = 80W
6 cell 5200mah 1.11v liion
80/8=10 hours * 50-70% efficiency... = about 5-7 hours theoretically when the computer is idle.
expect anywhere from 3-5 hours when under heavy load.

You should get about 30-50% more battery life with 9 cell battery.

 

Wow! I don't know why your battery life is so bad. I never got less than 4-5 hours with my new 6-cell.
