## Customer Reviews

### ⭐⭐⭐⭐⭐ Works Great with a Dell E7240
*by V***R on June 20, 2021*

I bought 1 battery from this vendor in April 2019, and it lasted two years. Very happy. Confession, I didn't really take care of my laptop, banged the battery around, had a messed up charger that wore the battery out. Two years later in June 2021, I needed a new battery. I bought a second one for my Dell Latitude and again fits perfectly, bought a new charger and hope this battery lasts longer than two years. I would definitely come back to this vendor to purchase laptop batteries.

### ⭐⭐⭐⭐⭐ This battery lasts an incredibly LONG time...GREAT!
*by A***T on December 24, 2017*

I am going to keep this review short! I have a Dell e-7240 and this battery lasts FOREVER! I'd say this battery lasts longer than the original Dell battery, even when it was new! Comparing it to the DELL battery..this one is just a BIT lighter in weight which had me a little concerned..BUT seems makes no difference at all. My only semi negative is, the fit is VERY tight. It fits, but it may be a micro millimeter off in size but not an issue. I just had to push it into a place with a tad more force than the original, but then fits just fine matches the Dell really well too as to color etc.. It seems to take a longer time to charge than the Dell battery, but it seems to literally last almost twice as long. I am super satisfied with this replacement battery...for the price I think you can't go wrong here!

### ⭐ Battery has lasted less than one year
*by B***F on June 26, 2021*

The first battery lasted about two years then swelled up and had to be disposed. This one has swelled up as well but in less than 10 months. It started throttling my CPU to 30% (checked by Resource Monitor). I thought my laptop was breaking down but it runs fine when I remove the battery. I do not recommend this at all.
