LB1 High Performance Battery for Acer UM08A31 Laptop Notebook Computer PC [3-Cell Li-ion 11.1V]

Before, my computer was good to go for less than hour. After, there are now six hours available. The difference is the new LB1 High Performance Battery. I knew the old battery was going after three years of heavy use, but had not expected the improvements that have been made in battery design.Among the excellent qualities of the LB1 High Performance Battery are--about six & a half hours capacity--super-easy installation (just check all packaging has been removed)--new design adds stability through a built-in extension---see product picture--an amazingly inexpensive & much appreciated low Amazon priceNot sure if this is the correct battery for your machine? Users should take out their old battery (on the Acer Aspire UM08A31 laptop, push the small button on the upper right toward the right when the Acer is face down. put your fingernail under the center of the battery pack and pull out the battery pack). The information listed on the Amazon product description above should match what's on your old battery.Any negatives? None at present. Other reviewers have been concerned about short battery life after a few months. So far so good for my battery, however. Also, users should expect the new battery will generate more heat than a very old one, such as mine was. I also am unsure about the actual manufacturer because the box did not have this information nor did it have the product information exactly as described in the product listing.I could not be more pleased with the quality and value of this product. Highly recommended.

I was very upset to receive the wrong battery from the seller. I do not live in the US, and returning it is not a sensible option due to the cost of returning it. It was sold to me by Powershow. I ordered it by the correct part number as above, but the battery I received is not as described or pictured. It is a much wider model, and does not fit my old Acer netbook AOA 150. It actually came with a paper with the part number on it as UM08A31, but the battery is anything but that. Avoid purchasing from the seller who is too busy or lazy to actually match the product with the part number before packing and sending it. I have an old UM08A31 that will not hold a charge. I actually need one that will hold a charge. Powershow sent me the wrong battery. It is as bad as sending a Ford part in place of a Toyota part. I cannot review the battery that I received, as I do not a have a suitable laptop or even know what product it is for.

My Acer One netbook is an early model from 2008. At that time I purchased a six cell battery as the original three cell did not have the capacity that I required. After about three years, the six cell battery declined in its ability to hold charge. I replaced it with this one. So far so good, I've had the battery for about 3 months. This battery has a little higher rated capacity than it's predecessor, which shows up as an extra hour of use. On my model, I get about four real hours. Without disk access occurring, the battery monitor says that I have 5 hours, but, a real 5 hours seems unobtainable.No problems, recommended.Update: I've had the battery for four months now and have used it constantly, many charge-discharge cycles. Still working as above. The the fact of the extra VA rating has turned out to be a big help to me.

The best battery for my Acer (AOA150)! I don't use that adverb often but this is a great battery. I bought a 9 cell a few years back, had to return it after a week. This one displays 7-8 hours after the second charge and I'm getting about that. My old 6 cell gave me 5-6 hours to start and after a few years went down to 2 (which was OK). It finally died. Btw, cold temps seem to kill these batteries, I was keeping this computer in the glove but I think during the winter months I won't. For casual use, I still love this thing! Who needs an IPAD?

This is a larger battery than the standard 3 cell battery the Acer AspireOne netbook comes with. My battery life was down to about 30 mins after the first nine months, so I ordered this replacement 6 cell battery.I was told that the larger 9 cell batteries can put a lot of strain on the connectors for the Acer netbook, and you have to be careful how it's handled. Since this netbook is used by my son at school, I thought it might get some rough handling in backpacks, and so settled on the 6 cell battery.Price was great, it arrived quickly, and has worked fine.

My Acer Aspire One netbook was a refurbished model. The computer functions great, but unfortunately, the battery life was disappointing, and the battery was short lived (not quite one year). I decided to make it worthwhile and purchase this 6-cell battery, and I'm glad I did! The downside to the 6-cell is the extra bulk that it adds to the underside of the netbook, so it's a tight fit getting it into my carrying case. But the extra battery life is worth it! I ran my netbook for 20 minutes and installed software during this time (heavy fan usage), and the battery life only dropped to 95%.Very satisfied!

I purchased this battery for my Acer Aspire One netbook. The original battery was down to an hour of use on the battery. Previously it had held a charge for just over two hours. I purchased this battery on Amazon because it was considerably cheaper than at the nearby battery store. For the price I paid, I was expecting about the same time as the original. I was pleasantly surprised to find that I have at least 6 hours of power and that includes when I have a two blade cooling pad in use that draws power through a USB port. When this one needs to be replaced, I will purchased another one like it. Well worth what I paid for it.
