This battery saved me from having to buy a new laptop. I have an HP laptop and the battery had swelled and broke the mouse.My husband used the plastic pry tool included to open up the laptop. Unfortunately my laptop would not release completely. Whether that was our inability to get it off, or the way my laptop is made, I'm not sure.We still had room to get the old swollen battery out and the new one installed.I let it drain as suggested in the instructions before the initial charge to 100%. It charges up very fast and works great.I would purchase this battery again.

Saved a lot of cash by doing a personal repair. Easy to do and battery was a perfect repair. Still working great.

Battery life is perfect!! Very easy to install and I also ordered another one a few months ago.

To begin with, I am a retired IT field tech.My laptop is an HP 17-by0061st, roughly six years old. The current battery is definitely bad. Upon removal, I saw that it was bubbled, and the diags confirmed that it was due to be replaced. The laptop, when powered off, would reboot instead of powering down.This battery part number for the battery from the HP manual matched the part number provided here, L1119-855. However, the MwAH was higher on this part than the original battery.Nonetheless, I installed it. I had some initial boot issues on first boot. I don't know if that was related to the difference in MwAH. Once I passed that, things were fine. My shutdown issues were resolved. And the battery reaches roughly 50% depletion after more than 2 hours, which is about the same run time that I had when the laptop was new.The install manual included with the battery said to fully discharge it to 2% then do a complete recharge. On Win11 you don't have the option (With this laptop) to reach a 2% level. It automatically go into sleep at 10%. There is no way that I am familiar with to adjust that lower. However, following the built-in limitations did not prove to be an impediment.I read some reviews that said that the included screwdriver was inadequate. While I have my own tools, I did use the supplied screwdriver, and found no problem.Allow me to provide a hint on screw removal. Laptop screws are rather small, and easy to loose. Grab a bowl, and put your screws in that as you remove them. In fact, have multiple bowls to put screws from different laptop parts in (One if you have a screw for an optical drive, one for bottom screws, etc) I use left over lids from peanut jars.Two other hints. One is, don't work on the laptop next to the edge of the table. Move the laptop a foot or so away from the edge of the table. That way, if you drop a screw, there is less chance that it will fall on the floor.The other hint is that if you drop a screw, don't try to catch it. Instead, follow it with your eyes to the floor. If you try to catch it, the probability is low that you will catch it, and the odds increase that you will lose it. Especially if your floor is carpeted.

work great

Beware if you are putting this in an HP laptop! The laptop will not recognize this battery and will tell you it is not charging. Once the battery's factory charge drops too low, the laptop will shutdown, and you will not be able to restart the laptop because now the battery is drained. The power adapter won't help because the laptop refuses to charge this battery.Research online says that most HP laptops will only recognize an authentic HP battery (which this one is not).

I ordered this replacement battery and it fit perfect into my computer and was almost fully charged. I haven’t checked to see how long it lasts yet.

Works well.
