The battery in my laptop was dying. I bought this a replacement. It's been in my computer for a couple months now and seems to be working fine. Definitely improved time I can work unplugged with my laptop. Nice that they included tools for the job.

Renewed life to an amazing laptop

I purchased this laptop battery expecting a reliable replacement, but it turned out to be completely useless. After installing it, I charged it to 100%, unplugged my laptop, and within five minutes, the battery died. Now, my laptop won’t even turn on!This is unacceptable for a product that’s supposed to extend my device’s life. Either I received a defective unit, or this battery is just poor quality. Extremely disappointed and frustrated—waste of money and time. Avoid at all costs!

Perfect fit! Comes with all the tools to open and close the laptop - all you have to do is set aside the time, clear some space and in 15-20 mins, you're back to having a laptop that doesn't "poop out" way too soon from an exhausted battery.

Easy installation, perfect fitIt was exactly what I needed.

EDIT:About 8 hours after I left my review, I was contacted by the seller through an Amazon chat. They apologized for the inconvenience and asked for my address, and they sent me a new battery free of charge, free 2 day shipping, no return needed. I installed the battery and now have a functional laptop again. Updating to 4 stars as the battery works just fine and I had no issues with installation. Customer Service def gets 5 stars in my book.Original Review: 1 starBattery nonfunctional out of the box. It fit perfectly, was the same type of battery, but when I transfered the cable to the new battery and installed it, laptop refused to boot from the battery. When turned on with power cable plugged in, booted fine, but as soon as I removed the power cable, laptop would shut down. I thought it may have been the internal power cable, but I plugged my old battery back up and had no issues.

Battery was easy to install and provided 4 - 5 hours of of unplugged heavy laptop usage before requiring recharge. Initial impression is that this is a solid battery replacement for my Dell XPS laptop. The true value is how long it lasts and the jury will be out on that one hopefully for a couple years!

Funciona mejor que la que trae de fábrica, aunque tampoco dura mucho para un uso normal me duro 4 hrs. Pero en comparación a la anterior que me duraba 30 Mins me va mejor con esta, adicional cambiarla no cuesta porque trae las herramientas que se necesitan, me gusto esta compra.
