Works exactly as described. Be sure to check out some videos that show you how to properly charge these up to start. That will lengthen the life of your battery! People still leave these charging overnight or even longer allowing the cells inside to burn out prematurely and then wonder why their batteries don't seem to last very long. A little common sense goes a long way when it comes to battery maintenance.I currently have a 13 yr old laptop which is still using it's own OEM battery. Yes, the same on that came with it! Luck? No, properly using it as it should be.Never charge to 100% unless absolutely necessary. 80-85% charge limit will make your battery last for MANY YEARS! In special cases (limited), if you don't have access to a charger you can charge to 100% but don't do it regularly, it will kill the battery lifespan!These work and I expect it to get a good 5-10 years of use easily.

Was exactly what it said and fit perfect

Perfect to have extra battery on the go for a laptop used in field work

Battery life is no good

Perfect fit for my computer, and easy to replace. My old battery charged, but wouldn't run the computer on battery power. This battery resolved the issue, and had an amazing side effect Previously, under corded power, the mouse pad left- and right-click areas were not recognized - I had to use an external mouse for these. But with the battery upgrade, my computer works great on battery power and the mouse works perfect on both battery and corded power. Very nice unanticipated side effect!

Well, I'm not sure how to rate this battery. I installed it into my wifes Gateway NV57H13u laptop and it fit perfectly. Powered it up... nothing. I plugged the charger into laptop and it booted right up. Quickly checked the battery level and it indicated 1%. So clearly the battery was delivered dead. I charged it up to 100% and used the laptop for 3 hours before charging it again at 8%. It charged up fine. That was only part of my concern, I'm wondering how the service life will be affected. These batteries do not like going flat for any period of time. As I said, form, fit, function was excellent after charging. Delivery was to wrong address--but that is on Amazon, not the seller.Update: Charged battery to 100%, used for 2 1/2 hrs (30%). Laptop shut off and on plugging in and restart battery showed 1%. This battery is bad.

Very good product. This battery is working very well.

When kid 3 who is now in college complained that his laptop wasn't holding a charge and he needed it for a presentation at a conference I'm sure he was hoping to get a new device. I ordered this with the promise that if this didn't work we would get him a new device. It arrived quickly with the pry tools and little screwdriver. I did watch a YouTube video and will also note that I've taken laptops apart to add memory in the past. I was able to find all the screws and get the device open and popping in the battery was simple. Putting the back cover on was a little tricky, but much to kid 3s surprise, I managed to get things put back together without breaking anything or ending up with extra screws. The battery seems to hold a charge far longer than before. The only small issue was that once removed the rubber stripes that hide some of the screws are less likely to fit well.It's possible that kid 3 really jut wanted a new laptop but for now I'll save the bucks. Under 30 bucks VS 800? It's an easy choice
