how long is a 9cell supposed to last?

How long does a dell 9 cell battery last?

 

Hey there....I think usually bet. 1-3 years! It all depends on the usage it's getting!
And, over time batteries start to go downhill slowly...lose their *juice* per se!

Here is a great guide on Batteries!

Depends on the notebook, configuration etc

 

Unless you mean how many hours per charge.
In which case read above post.
I've found 6 hours on my Inspiron 1520 (T7250, 8600M GT)

 

You need to tell us what computer you are talking about before we can say a word. Some computers can get 8 hours on a 9 cell, others manage 2.

I can't give you an answer without information.

latitude d620

i just bought an oem battery off ebay and now i'm wondering if the battery's any good

 

You should be getting somewhere around 5-6 hours or so, depending on the hardware in the D620.

The battery itself will likely last around 2 years, give or take.

i'm getting 3-4 hours

 

@archaic, Download Everest from Lavalys.

I don't know if the trial version will show you this, but anyway: run it, and go under (in the program) "Computer" > "Power Management". See "Wear Level".

It will show you how much the battery was used.

 

my d620 with a 9 cell really doesnt last that long, but again it depends on what im doing with it. Also when i switched the mobo to the nvidia card it uses alot more juice
