Fit perfectly and works perfectly

I had an old Asus Q550LF that hadn't been powered on in years. Manufactured in 2013. The battery didn't just not hold a charge: it basically didn't exist. I wanted to use the laptop as a virtual machine host for screwing around with IT stuff for certifications, so I went in on this little nugget.Pretty solid battery. I haven't used it enough to see whether the capacity rings true, but it's right at the 4,000 mAh that the OEM battery is. I wouldn't be surprised if the OEM battery is "nicer," but I'm basically throwing a Hail Mary to squeeze more utility out of something old enough to ride bikes after dark.It actually comes with a neat little spatula and a surprisingly high quality Phillips head screwdriver. Old school acrylic.You're not getting any extra battery life, you're getting a new battery for cheap. It takes a delicate hand to install, but I'm coming from car and gun stuff and not disassembling/reassembling crusty old laptops. But, all you need is a tiny Torx driver to pull all the visible screws. A tip: To get the bottom plate off, I had to pop open the DVD drive to get it started. Don't try to pry it. If that doesn't work, wrap some tape sticky-side-out around your fingers and try to give it some pulls.Update after a week's use: This gives me a solid four, maybe five hours of battery life doing light office activities on Ubuntu 22.04 LTS. It's obviously going to depend on your brightness and load.

Just what I needed. It will do what it needs to do. I can't say anything else because I haven't used it yet. I will update as soon as I use it.

Item as described. Was truly plug and play for my old Q550LF. However, first battery arrived DOA. Would not start or take a charge, even after left overnight. Replacement was sent immediately without question and arrived within three days. Replacement battery working fine. Provides about 5 hours of charge, depending on screen brightness and workload. Stock battery gave me a bit more than that (when it was new), but I have no complaints.

Worked like a charm. Easy to install. Charge speed is fast.

Battery lasted less than 2-1/2 months. Purchased May 3. 2 weeks ago it went from being able to power my laptop for 12 hours to zero power within a day or so.. Windows 10 and Lenovo battery evaluation software report the battery as being dead. It reports that it's 86% charged, but won't take a charge and the laptop immediately turns off when unplugged from power.

Perfecto justo lo que estaba buscando

No need to add pictures, it matches my laptop as specified (and chosen). Battery came at 63%, and I used for about 145 minutes, and it went down to 18%, haven't had the chance to do 100% to 0%, but it worked out of the box. Now is the lifespan test, time will tell.
