I bought this battery for my laptop as a replacement, and so far it has exceeded my expectations. Installation was simple and it fit perfectly, without needing any additional adjustments. Since I started using it, the battery life has been excellent, allowing me to work for several hours without being plugged in. The laptop feels stable, doesn't overheat, and the performance is the same as, or even better than, the original battery. Furthermore, the charging time is reasonable, and it maintains a consistent power level. Overall, it's an excellent option if you need to replace your laptop battery. Good quality, good performance, and a very recommendable price-quality ratio. I would definitely buy it again.

Works very well

Just perfect. Perfect fit.. perfect charge and was powered enough to use immediately. Arrived a day early. Great Seller and I highly recommend.

It fits my dell 3521 very well. It last little over 3 hours (little shy compared with the original battery). At the price I will recommend as a “buy”

The battery is compatible with my Dell computer. The battery that came with the computer lasted almost 8 years. I don't know how long this battery will last, but I'm sure it will outlast the computer! This battery functions well. I have noticed that I've picked up a little speed since replacing the bad battery.

Perfectly compatible to my aging laptop

I bought this replacement battery because right in the middle of using the laptop, the factory battery with 62% charge, I got a bizarre message stating that the battery had experienced a permanent failure and had to be replaced. Seriously? It had just gone 7 hours running the laptop and was in the middle of a recharge. Online references didn't help to solve this issue. Was about to junk the laptop (Dell 15" i7 from Costco about 5 years ago) when I happened upon the reviews for this replacement battery. So? The reviews are right. The battery is awesome and runs my laptop for at least 8-10 hours with my putting it to sleep a little bit every couple of hours. Very happy and saved myself $1,000 cuz I don't have to buy a new laptop. Yet...

Misleading advertisement. I bought this wanting a 65Wh battery and this is being shown here in my terminal as 57.72WH much lower than the factory battery as well... I don't recommend getting batteries from this company

I have an older Dell computer that still worked great, decided to gift it to my mom but I needed a new battery. This battery is awesome, holds a long charge and works great. Was packaged well!

It is a good quality battery, and work better than the one come with the laptop!

Durée de vie de la batterie inconnue pour le moment! Durée de la charge est de 4h à peu près!

Looks good so far - no issue for now

Works great
