Fair life
The battery life for the replacement is not nearly as good as the original was. I could easily get 5 or 6 hours of use on the battery when I purchased and with the replacement 2 hours is the maximum.

Pretty Good
My previous battery had started out lasting 8 hours, but decayed to only 1.5 after a while. I got this one as a replacement and it lasts more in the 6 hour range with the screen brightness at max level and active usage. It works pretty well.

A necessary buy for a P51
The P51 (especially with 4K screen) is very power hungry.
For airline travel, you'll definitely need this battery. Here's why:
The P51 power brick is giant. At about 1.5 pounds, it's luggable. The overall power picture, though, is the machine's weakness. For air travel, I bought this extra battery immediately. When I plug into an AA power port, the machine warns that it's on airline power, which isn't enough to drive the machine. Instead, it draws power from both the power port *and* the battery, so the battery drains during flight. You will not land with a full battery ... beware. I have tried running only with battery stretch mode: the machine is very sluggish and the screen is dim. I haven't needed to push the machine to max performance yet ... but I expect only a few hours per battery in this mode. Considering this, I now have a 90W power supply (LVSUN LS-PAB90S-2U) that I'll be trying on my next trip. It's much smaller/lighter than the 170W brick and may do just as well. Though I'll probably find myself wishing for the brick once I get to my destination. The jury is definitely out on this. FWIW, the machine *will not* run just on seat power ... it really needs to draw on the battery, too.

Love the removable battery on Lenovo computers!
I love that Lenovo computers have a removable battery -- my computer is about 5 years old... still works great, but the battery would no longer charge. Went online, purchased a new one, and about a week later I feel like my computer is brand new again (well... lightly used). Thank you Lenovo!

New battery couldn’t be easier!
Right purchase. Slipped into its place on the back of my Lenovo P 53 like a glove. Came 50% charged, and began charging right away. Absolutely no hassle of any kind whether it’s finding, purchase or delivery!

Lenovo Sucks
Never received my battery. Can’t get them answer me on where it is. Will never buy any of their products again.
