Question: The battery I recieved has the same pa3534u-ibrs number but it has 4400mah on it instead of the 4000mah like the original. Is this the correct replacement?
Document: I, like many college students, depend on my laptop a lot. My battery was dying really quickly, so I wrote down the numbers on the old one, and matched them to the numbers on this battery. When I recieved it, it was ONE number off. I took it to the tech center on campus, and they said it should be okay, and even helped me put it into my laptop. It didn't fit as nicely as it was supposed to, which should have been a warning sign.
My experience is that although it was the correct battery for my laptop, it didn't particularly fit as nicely as the original. In my opinion, it also didn't seem to have as long a charge, and my laptop motherboard fried about 6 months after purchase -- I have no idea if it was related or not, but the computer is gone now so it's not like I'm using the battery anymore anyway.
This is the second time I have ordered this battery from the same company and both times when I received this battery it was not the correct model number!!! The listing on Amazon says model number PA3534U-1BRS, which is also listed on the label on the battery box, but when it was opened, the model number on the battery was PA3534U-1BAS!!! As you can see the last three digits are not the same, so the battery does not work!!!
The replacement battery I received is excellent. Instead of having my computer constantly plugged into the charger, I can now use my computer without it. Thank you very much for such a wonderful product
I wasn't sure if this replacement battery would be worth the cost, but decided to try. It works great. It arrived quickly and now the laptop works with the battery several hours instead of a couple of minutes.Thanks
Seems to take a long time to charge and a short time to discharge. The reason I bought this unit is that Windows declared  my Toshiba battery had bit the dust. And, because a puppy attacked the cord on my Toshiba adapter I decided to buy replacements for both units. I don't like the battery so much. I hope I am blaming the correct unit for my dissatisfaction. Windows likes this unit, but given my early experience I don't know how long Windows will stay happy.
was happy with it at first, but noticed the battery time was less than the original. then after a few weeks of use, the battery time really diminished. After a few months it holds a charge for about 15 minutes at best. FOr the price, I guess its ok. Still need to have the charger close by, but instead of the original battery that was totally dead, at least I can change rooms without rebooting.
I was skeptical because of price point. I did several searches for the correct one for my laptop and finally chose this one. It came 75% charged. It works flawlessly and holds charge no problem. It even last longer than my original battery. Over 2 hours.
This battery replacement is excellent for my computer, it works just like the original one. It have the same duration of the original.
We purchased this as a replacement to our original battery and it is ok but not great and we get nowhere near the time we would like to have. Generally we are only good for about 2 hours max.
Answer: i ordered the same for pa3534u-ibrs number and what i received has worked just perfect. battery last a long time.
