Great battery for the price!! Review by Rebby
How do you rate this product?
Great batteries!! I would recommend these to anyone looking for a replacement battery for their emachine e525 or other compatible computer. They last somewhat longer than the "stock" battery that came with my laptop and I am 100% satisfied with these replacements!! (Posted on 10/24/2015)
Price ! Review by Kingston
How do you rate this product?
The price is what sold me, I have installed it in my laptop, charged it overnight , used it to let it run down then recharged it . The battery holds a charge for about an hour and a half with my settings on the laptop which is long enough for me. (Posted on 9/1/2015)
Something needed. Review by Gaylord
How do you rate this product?
There really isn't too much to say about a battery, except that it fits, it works and now I have to wait and see just how long it will last and hope that it doesn't leak, etc.. The batteries were well packaged, by the company for mailing and the price seems to be very decent. (Posted on 8/20/2015)
Great Review by Coby
How do you rate this product?
Perfect, and pretty cheap. Some websites had this battery for 80.00 and I figured I could find it cheaper, but was surprised to find it for 20.00 on LB1. The replacement battery gives me more time unplugged than the original that came with the laptop. (Posted on 8/4/2015)
Works exactly how it should! Review by Tom
How do you rate this product?
This battery fits my computer, an emachines D525, perfectly. It holds charge for 2+ hours which is a welcome change from the 5 or 10 minutes of my original battery. It's greatly improved my ability to use my laptop efficiently. Plus, you can't beat the price! (Posted on 7/15/2015)
I did a fresh install and the battery has been great Review by Robert
How do you rate this product?
My daughters computer was a mess because the battery was gone and it kept powering down. This contributed to the hard drive been scrambled. I did a fresh install and the battery has been great. The price is a fraction of what others sell them for and so far just as good. (Posted on 6/17/2015)
Awesome Charge! Review by Rob
How do you rate this product?
I choose 5-star rating because I bought a battery that was supposed to be 97% good battery but I received an excellent battery. I get 3 hours on one charge where before I was only getting 1 hour.Thanks so much for getting me exactly what I needed to be able to play online without battery failure interruptions.

This Battery saved my computers life Review by Belli
How do you rate this product?
This Battery saved my computers life and me a lot of money. As a poor college student I have the goal to keep my computer all four years of college. When upon my last year my original battery was zapped and would not hold a charge. Thank to this battery my holding time has increased enough to not have to be right by a plug. (Posted on 4/22/2015)
Works just fine Review by Mark
How do you rate this product?
Fit my emachine E627 just fine. I was concerned about that, but it fit like a glove. I was very happy to see that the power on the batter lasted about 2 hours. That's through just surfing the web and video playback as well. I've had it about a week and have no complaints. (Posted on 4/14/2015)
Good product for the price! Review by Peter
How do you rate this product?
Are you gonna get 4 hours of battery life? No. But given that most laptop battery replacements are over $100 easily, this battery is a great buy! You can't beat the price! I actually ran a movie on full charge and was able to get about two hours before it drained out. Not bad for a $20 battery!!! (Posted on 3/4/2015)
