My laptop was really old and the battery finally ran out of charge and didn't think I could find a replacement. I was surprised to find one especially for such a good price. It works well and haven't had any problems. Don't know the battery life yet because I recharge it every time I'm done with using the laptop. I'm usually on the computer for a couple of hours. The longest is probably 3-4 hrs.

Be sure to not leave your laptop pluged in for to log as you can damage the batter from over charging it. The batter gives me about 3 hours of use time when fully charged. Personally, I lave my laptop ungluged once the batter has been charged. However, If you are using your laptop for longer than 3 hours its best to remove the batter for the time until you need the battery. Over all its a great price for a laptop battery.

Easy to install with a great price. I’d thought the battery would last a bit longer, as I’d plugged it in in the morning, charged fully (which didn’t take long) but by late evening it needed to be charged. But given the fact that I had to use my laptop plugged in all the time, I’ll take it! Hoping with use the battery will stretch.

Me preocupaba que no funcionara por ser generica, pero total normalidad.Hasta en mi casa hubo bajadas y subidas de voltajes, la enchufe sin protección y la pila perfecta!Vamos a ver cuanto dura. Hasta ahora perfect

My old battery died after years of use. It wouldn't hold a charge so I found this one at a reasonable price. It fit right in the slot of the computer and charged up quickly. I use my computer as a media hub and the battery works great! I've had the battery for about three months now and no complaints.

Holds a charge threw out the day gaming, but not as well as the original one.Then needs to be plugged in.Good enough for old laptops that still work. My Dell has been going strong since 2009.This battery replaced the original one I and works fine.

This battery gives me about 2 hours on my laptop. Considering my old battery would not charge at all I am happy to have something to use. My laptop is about 7 years old and this battery gives it just a little more life before I have to replace it.

These batteries are pretty good. I ordered two one for me and one for mom. One was good and the other was defective and wouldn't charge. The company refunded my money right away and I purchased another one. Excellent service and both working great and last a long time. Good people to deal with.
