I would always go with this seller since my battery was dead and I randomly bought it and now it works amazing and last waaaay linger than I expected.5 stars

Works great. I hope it lasts a long time, easy to install.

It works

The battery was a perfect fit, looked just like the Dell battery and the fit was perfect!

This battery went into my wife's Dell 17-7779 laptop. After checking out a YouTube video, to get an idea about the job, I decided to tackle it myself... the job was quick and easy, the necessary screws drivers were supplied, although you only need the Philip's headed one...one caveat about using the video..it doesnt address the instructions on the initial set-up of your battery like the included instructions want you to do...so dont forget to follow the instructions on what to do after the battery is replaced because there is a small sequence of events you need to perform to maximize the longevity of the new battery...this was a very good purchase that gave me a reason to open up the laptop...lol..took about 15 minutes

Purchased this replacement battery at the end of Dec. 2022 and it has never held a charge without being plugged in and now my computer gives me error messages that the battery is not compatible with my Dell.

This battery was an exact fit, holds a great charge and lasts a very long time. Extremely happy with the quality and speed. Five stars all around!

Battery fits perfectly and works perfectly for Dell inspiron 17-7778 model.I’ve not tested for more time, definitely works fine since it’s new and not sure how much it will last for. May be it will last for couple of years..

Showed up fast and was easy to install, I have never changed out a battery before. Comp is working great!

La durée de charge est environ 3 heures 1/2 a4 heures

I didn’t get the screwdriver to open the battery.

This battery is not OEM, and it's 55Wh and not 56Wh. Besides that, it works fine in my G7 from 2018. It replaced a swollen battery that didn't last for 45 min, and it last around 4h now if not gaming.
