The title for this listing says "6400mAh Extended Battery", but the tech details says "2 x 3100mAh Battery". MAJOR difference. Please clarify?

Almost all of the huge after-market batteries are really just multiple batteries in a same housing, wired together so they basically act as one battery.

Since there are so many sellers, I can only confirm that the battery I received says 7800 mAh. Battery life was about what I had been getting from the 5200 mAh 6 cell that the thing came with (before that battery started to die).

Apparently it depends upon which vendor you choose to purchase from on Amazon. My original battery had 8850 maH capacity, just like Andrew mentions below. However, the battery that I received has only 7650 maHs of capacity so I'm debating whether to return it. The part number for my original battery is 636631-001 while the new battery is 593550-001 but appears to be new and a genuine HP part. Apparently HP has offered multiple batteries with different part numbers as a MU09 battery. I purchased my battery from Amazon through Mobile Parts Pro. I'm curious to compare the capacity of batteries purchased from other vendors under this same Amazon item number. Apparently it depends upon which vendor you choose to purchase from on Amazon.

Truthfully i didn't pay much attention to the mah number. On amazon i entered the phone type and weeded out the battry from there. The battery was a bit different than my original in that the connector was 2 separate pieces instead of 2 wires attached to one connector. I hope this helps at least a bit

You should contact Sony or look up extended battery on their site to make sure. That's how I did and got the product info and then looked on Amazon to buy.

If you can find a 5900mAh rated battery, it would be better. the higher the number, the longer it will run on a charge. When you buy any of these generic batteries, try to make sure you can see an accurate picture of the side of battery that has the battery info and make sure it's in the item description so when you buy it, and it turns out you get jipped, you can throw that in the sellers face. Too many sellers have descriptions with their items that are not what they say they are.

Good question. If the battery said 1500 mah on it, how do we really know its 1500mah? Think about it. A lot of batteries are overrated anyways. I don't see how anyone can go wrong at this price point, so just buy it and enjoy =D

Voltage is the same.. mAh rating is overstated. It doesn't last as long a genuine battery but for the price I suppose I will live with it. Probably 20% less run time. Also energy retention isn't as long.

The battery depicted in this picture does not appear to be the same one that I purchased. The one that I rated was white with a blue label, and it indicates 950mAh, 3.7v, and a serial # S.S: NTA2340, L/N: 0108. It was advertised by several retailers as being the latest version. Hope that this helps you out.

It's best to confirm the replacement version with Anker, especially with HP. HP's part numbering policy doesn't always work the way one would expect. Voltage rating and interface need to be confirmed. A 12 cell battery will be physically larger, with the body of the battery extending out the bottom of the laptop along the length of the battery. This puts the laptop at an incline so the top of the keyboard (Function Keys) is higher than the bottom (space bar). I like the change as it makes the keyboard more comfortable to type on. It also allows more air circulation under the laptop.

The battery is larger than the original, 20x26x6mm and 5.89g versus 18x22x6mm and 4.68g (including wires for the weight). I had posted this in a review earlier...

Hi, I'm not home at the moment, but I believe I still have my 3500 back and battery. I also got the smaller extended battery option (2100 or 2400 I believe) and ended up using it instead. You can have mine if you like. Louis

An swer here..when i purchased the batterys i was looking for a good long lasting battery an not a legal battle over technical stuff. Also in your question you wrote with current tech only about 3600mah. Notice the word about! You may be correct but you may not have found all the facts yet either. But beside all the technical an nit picking things it is a good battery an has served its purpose for me so far.

Unprotected, more mah means lasts longer, also this seller sent me 18350 instead of the 18650 I ordered and one is twice the size, hard to mistake one for other. Beware of this seller

It has been a while since I replaced my battery but I am almost certain that it was a 550MAH. The new 700MAH is working great.

It was supposed to ship with the 4400 battery right from the beginning but acer didn't have enough 4400mah batteries in stock which is why they decided to ship the first batches with the larger battery. That is what I have read, I will provide a link should I find the article, or just google it.Anyway, I also think that all aspire ones should come with the larger batt. a downgrade like that seems a little unfair.
