TREE.NB 8N0T7 Replacement Laptop Battery for DELL XPS 15 9575 Precision 5530 2-in-1 Series Notebook 08N0T7 TMFYT 0TMFYT 11.4V/75Wh 6-Cell

Perfect! It was exactly 60,002 mWh as I checked on the battery report on my laptop and it last up to 8 hours with just regular browsing this is perfect! And for 29 dollars is even better! It's charging speed is better than I thought and it fit perfectly. I got no warning from the system of It being incompatible so that means it's just right.

My old laptop which still work great wasn't keeping a charge anymore and after opening it, and getting the information, I needed this battery. I replaced it myself. I have never replaced a laptop battery before, let alone open a laptop. One key didn't work after replacing it but it wasn't the battery itself, it was just the way I put the laptop back together. I have used this battery for one year now and have no issues. It's like it's a brand new laptop

I purchased the battery for a Dell Latitude 7390 2 in 1 as the original had degraded down to about an hour of battery life. OEM replacement was around $100, so I took a chance on this one for $30. Install was pretty straightforward but a minor issue was the cable on the new battery was a bit longer and the connector was a TIGHT fit. Took some serious force to get the pins into the socket and some monkeying to get the battery to seat correctly with the longer cable. Besides that annoyance, the battery cells tested at 100% with diagnostic software and my laptop appears to be back to a 6-8 hour battery life. I'll update this review if the battery fails prematurely, but at a third of the price of OEM, if I get a few years out of it, I'll be happy.

We purchased the TREE.NB B31N1912 Laptop Battery to replace the battery in a ASUS Sonic Master computer. It arrived way quicker than I expected. It had about a 70% charge when it arrived. It came packed good, the battery box was inside a larger box, stuffed with brown paper. It was set in a little plastic shipping container with an open top to keep it from sliding around in the battery box. There wasn't any damage to the battery. The battery fit right into where it was supposed to, BUT make sure you don't slide the little connector too far back where you put it in or you will make a quick job an hour job! So needless to say that is what we did, so installation took longer than it should have, if that wouldn't of happened, it would of installed great! It came with a little screwdriver and a plastic thing that looked like a small putty knife to put it in with. It fit into place properly and the screw holes lined up. It charged to full fairly fast, but it seems like it doesn't hold the charge the best, so I'm not a whole lot impressed with the battery life. The old battery quit working a couple of months ago, so this at least lets me move the computer around, so it works okay for the money. I am a little disappointed on how long it holds the charge, that is why I only gave it 4 stars.

Fits loose but it works

Bought this battery for my t480 in February. June 18 it is no longer recognized by the laptop and will not charge or recognize the battery. I decided to go against the reviews saying it would break after a fre months.. and here I am.. it happened to me too. Highly disappointed!!!

I got this as a replacement for the RR03XL rechargeable battery for my HP Probook 450 G5. The battery works, plain and simple. However, I don't know long it lasts on a single charge because I literally just finished installing it and I always have a multitude of applications running at the same time, so I'm not sure that my usage would be considered moderate. Also, while the replacement battery comes with a pry tool and screwdriver, you will also need a T9 and T10 screwdriver (which are NOT included) to perform the installation. BUT...Take my Advice (this is about the installation, not the battery itself) Get a professional to do the installation. The battery for the HP Probook 450 G5 is embedded deep inside the machine beneath the keyboard, requiring the laptop to be almost fully disassembled to replace. There are also a number of sensitive electronics to unclip from tight spaces so the risk of fatal damage to the keyboard (and/or backlight), power button, finger print reader, trackpad and audio jack port is very high. I doubt that this battery was meant to be replaced by the end user; let a professional do it.

My computer hasn’t recognized the new battery and I’m still getting the same pop up. Prolly a software issue I need to figure out not sure yet.
