SR03XL L08855-855 Battery Replacement for Hp Pavilion 15-CX 15-cx0xxx 15-cx0058wm 15-cx0056wm Envy X360 15-CN 15-CP 17-BW Series for hp pavilion laptop 15-cx0xxx battery SR04XL 52.5Wh 4550mAh

Fit perfectly, EXCELLENT instructions (which is so rare I have to call it out), charged up and held a charge. I hope it lasts but my original battery was HP branded and swelled up like a balloon, so I don't see the value in buying a name brand.

I got this battery as a replacement for my old HP Pavilion Gaming Laptop battery. I have had this laptop for a little over 5 years now, and the battery that it came with has been severely detoriated as a result of regular use. I would get about a hour and a half of battery life before I had to connect the charger, pretty rough.Luckily with this replacement battery I ordered, I can use my laptop for several hours now without having to worry about hugging the nearest wall to keep it alive. I can use my laptop for about 4 or 5 hours and barely cross the 50% mark. So far I’m pretty happy with this purchase.

On the part of the business end, they were so fast in fulfilling my order. I live in a ho-bunk town where shipping is usually time consuming process.In addition, being a university student having a device that can work on the go is paramount. My previous battery would die after 30 min minimum and sometime wouldn't even hold a charge at all so I always had to find a wall outlet. After using my new laptop for a week or so I can manage on battery for 2-3 hours before charging. (Given I use it for product design on systems like solidworks this is a very long time indeed on a CPU intensive software.The packaging was superb and safe I have no doubts that a good amount of work was put into it. Thank you so much, this tiny upgrade has taken my "I need to replace this" laptop, back to feeling new again. Thank you Thank you Thank you.Great product, Great people. Period.

Purchased this for a 4 year old HP laptop. It was dying even in a bag for a day after charged. When that happened it would reset the BIOS settings and have to be set when turning it back on. I purchased this battery and it seems to all be working back to normal. Two things to note. #1 original battery had some foam on one side to protect laptop components. New one does not and it was not something I could peal and transfer easily without damaging. I am not sure on long term effects. #2 it did not initially turn on I had to plug laptop in then try to start a couple times and reset my BIOS settings. After that everything seemed to function normal. I will update if I have any additional battery issues. Hope to get at least a couple years out of replacement battery.

This battery works well for a replacement battery on my laptop. It came with the items I needed to install it. The battery holds charge and lasts quite a few hours. It was easy to replace the battery.

So far, this product has been great. It was perfectly compatible with my laptop. The screwdrivers were a definite plus! Overall happy with the product. One thing that could be better is information or presentation of warranty terms

It came with a tool set and some instructions for replacement. Considering the technology this battery works with, don't expect crazy battery life.

Good as new until further notice
