A great choice
My laptop just up and battery power shut off. I never thought of ordering a new battery pack after 4 or 5 years!!Looking on Amazon, there were 2 for my specifics, and I went with the lower price one with good reviews.After putting new battery pack in-charged in no time, and works like a charm! I am back in business!! Highly recommend this brand!!

SO far so good
I was pleased to find this battery. Others online say they are for the A41-X550A but the techs were off. This was the right match. I just received it and am on the first charge so I'll post an update when I know more. So far so good. It fits, it charged and I'm on my laptop. A new battery is better than a new laptop at this point for me. I'm happy with the purchase. But, time will tell....

End of Life In Less Than 4 Months
Initial analysis after the first several weeks of use on this battery displayed good performance and life. The duration generally lasted a few hours, depending on use, it gave no indications of overheating whether or not it was charging. Now, less than 4 months after initial use, it will not hold a charge. The battery indicator shows a rise to 100% in just minutes, then down to zero after less than 15 minutes.

Great replacement battery
Fits exactly the same as the original and holds at least as much charge if not more. I have not noticed any deterioration in its performance beyond what would be expected in the time I have used it.
