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

This battery fits well and installs without difficulty. The connection is secure and it works as expected once placed. It holds a charge properly and provides a stable performance for daily use. The build feels standard for a replacement battery. It matches the description and is a practical option to extend the life of a laptop.

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.

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.

Battery plugged in and 0% battery life. Too late to return to Amazon. Can't find how to contact seller. Beware this company. Addendum : I found out that battery needed calibration and I wish that seller had given instructions. My bad and the battery appears to be working well and I apologize to seller about bad review. Updated to a 4 star only because they didn't give instructions on how to drain battery all the way in a HP and calibrate.

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.

Battery is advertised as having 51Wh. I ran the "battery report" script in Windows Powershell and the software says the maximum design capcity was only 47,880 mWh. I charged the battery up and shut down the laptop. It sat in my office closet for a few months after that. When I went to use the laptop again, the battery was dead. I plugged it in and used it for a couple days and ran the "battery report" again. After only a handful of charging cycles, the "full charge" capacity is now down to only 30,278 mWh. That's a drop now to 63% of what it was new. The OEM battery lasted about seven years. This one is poor quality. It only lasts an hour or so before shutting down. I am writing this review because I went back into my account to see if there was any warranty left. Listing says one year, I am just outside of that, and I doubt the seller would do anything for me. Lesson learned. I should stick with an OEM replacement.

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.

Fits loose but it works
