Best Laptop battery replacement for Acer 1825pt?

[DiamondsareMine]

I have a laptop with a battery that needs to be replaced but I can't choose which one to get.

I found a "high performance" 6 cell battery that only has 4400 mAh but for some reason, it is more expensive than a 9 cell battery with 7800 mAh. Why is that? Which one is the better buy?

I think they are both third party. I just needed help on which one I should get and the pros and cons

3rd party seller. the 6 cell is by newegg. the 9 cell is not

Cheap laptop with advertised high capacity is about an 80% chance of dropping capacity to 1/2 in a month if not failing.

The 6 cell one is likely higher quality construction but any 3rd party battery is pretty iffy how long it will work, and especially how long it will keep a good charge for.

Of those two, I'd go with the 6 cell one.
