I say go for it.
The only thing I am NOT happy with is the listed battery life - I figure the battery was probably an original 2008 model and has had quite a bit of battery degrading going on (I estimate 65% gonna use a battery checker when it comes in to test)
Listed with it is a 6cell (Do cells matter in Laptop batteries? or just Voltage/mAh?) "Lithium Ion Battery - lasts about 1 hour"
I figure I'd so some Ebay searchin for the model number + battery and found that they seem to all be 7.2v
Now getting a replacement requires a little more effort though...
12 cell, 7.2v, 8800mAh
10 cell, 7.2v, 10400mAh
Comes down to the "Do cells matter?" question. I am getting mixed answers "yes, it's like how many batteries are inside" and "no, only voltage/mAh matters, if the voltage is the same simply the higher mAh is all you need to look at"
Prices are all over the place too, dang shill bidding and boosting prices. (like the 8 cell, 8800mAh for $400!)
One of the 10400mAh is running a whopping low of $30ish . Very affordable. New, 2 year warranty (overseas of course, but hey, what can you do?)
I just gotta get a definate answer to that big question " In battery life of a laptop, do Cells matter?"
Of course there is still the possibility that the ebay sellers just don't know what they heck they really have, and copy/pasted descriptions without actually looking at the device at all. This is what I believe to be the issue IF indeed amount of cells helps determine the battery life.
If I remember right... Volts X Amp gives you watts.... so Volts x mAh in this case would give you milliwatt hours?
But.. how do the cells factor in for this?
Does an 8cell, 7.2v, 10400mAh have more battery capacity (life) then an
12cell, 7.2v, 08800mAh battery?
I mean.. if based on Volts X mAh alone - voltage is the same, so higher mAh means more capacity. But if Cells have some factor in the equation - then this isn't the case, like... I dunno if this is the proper way to do it, but
12cell X 8800mAh = 105600mAh
8cell X10400mAh = 83200mAh
or a 22,400 mAh difference. But I have never seen any kind of equation based off of "Cell math" in battery life determination though, so...
I don't believe that is the case... can anyone correct me?
I couldn't find "Strike Through" option for edit, so I underlined.
Cells seem to be the amount of "little batteries" inside - in whatever form. But the mAh rating is already calculated for the TOTAL of those cells, I believe. Meaning in this particular case - cells have no meaning to me what so ever, besides adding weight.
Can anyone clearify this while I work? Gonna be gone for several hours.. I hope someone looks.
