Genuine Dell battery as advertised. As expected it works great.

While I can certainly say this battery was very easy to install. It took about 5 minutes to install and everything has worked very well the last couple days. The initial battery life is great. Not sure of the overall battery life down the road or the longevity as I just bought the battery but so far it is working very well.

Second time buying a replacement, Original battery lasted 3.5 years, this one lasted 2.5 year. Just installed a 3rd one, hoping it lasts a few years as well.

Easy replacement, fit just like the original. No complaints.

This has been an expensive disappointment. I decided to spend the extra money on the Dell OEM battery to ensure I was getting a high quality product. Needless to say, I have consistently been experiencing poor battery performance, even when using modest energy settings for my laptop. It seems this unit is not manufactured to the same quality specifications as the original battery. I now have to keep my laptop plugged in constantly but the battery is only 1 year old.I won't be buying Dell products in the future. I advise you to consider doing the same.

I was skeptical at first to order this figuring a OEM dell battery cheaper then what Dell was selling for, took the chance and when opened the box to my surprise an actual Dell Battery. I Have my laptop back to running for 5-6 hours like it was when New.

I thought I could save a buck and bought a 3rd party battery for my Dell Inspiron 15 7000. After several attempts and countless hours it did not work. The moral to this story is Only Buy OME Parts!! Received the Dell battery, installed, did the 3 charging cycles and all is good!! Now getting 6-9 hrs of use. Highly recommend!!!

Easy to install & saved a $100.
