Review:I bought this battery for my Lenovo IdeaPad laptop and I am very impressed with its performance and quality. It has a great battery life, lasting 5-6 hours offline and 2.5-4 hours online. It is much better than the original battery that came with the laptop, which only lasted 3.5 hours offline and 1-1.5 hours online. The original battery also went bad much faster. It's been a year since I've had this and it's still pretty good and I don't always treat it kindly. I put a lot of pressure on it's usage.The battery was easy to install, as it came with the tools needed and clear instructions. It fits perfectly in my laptop and does not overheat or make any noise. It also charges quickly and keeps power when not in use.I highly recommend this battery to anyone with a Lenovo IdeaPad laptop and needs a replacement or backup battery. This is the best battery I have ever used for any laptop. It is worth every penny and I would buy from this brand again. Hope they keep making laptop batteries and maintain the high quality of their service.Glad you liked this answer!

Nice that tools are included to install product

I wasn't sure how well this battery would work, but I'm quite pleased. The factory battery failed without warning. This one seems comparable in life and charge indication to the original in my 2019 My ThinkPad X1 Extreme Gen 2 when new. NOTE: The tools which come with the battery are wrong. I needed a PH1 screwdriver for all screws, and used the included 'guitar pick' to pry up the ribbon connector.

Product did exactly as intended! My old laptop could barely last an hour before needing a recharge. After installing this product, it is easily quadrupled in life. Very easy to understand directions and great customer service as well! Would definitely recommend.

Beware of ScorpioX Inc's Laptop Battery - A Disaster Waiting to Happen!I made the grave mistake of purchasing a laptop battery from ScorpioX Inc on January 24th, 2024 and it stopped charging altogether on March 3rd, 2024 - a mere 40 days later! This battery is an absolute lemon, and I'm writing this review as a warning to fellow customers: Do not buy this!

The battery itself fit perfectly and upon initial use seems to do the job. Old battery died within 15-20 minutes. Installed this one and charged fully and showing over 3.5 hours life. Had it on for an hour now, and it’s only down to 90% so seems to be working as required.However the picture very clearly shows tools included and I paid more for this one expecting tools and none were included. Only reason I didn’t return is because I don’t have time to return this and wait for another one that has the promised/expected contents. So basically I paid for something I didn’t receive. Will the seller or Amazon make it right?

The battery arrived quickly and was easy to install. The laptop now works well again. Included tools are a nice touch.

I got this because the OEM battery started to inflate from the gases being produced because it went bad. This replacement isn't the best, it doesn't hold a charge for long and it feels like I have to keep my laptop plugged in at all times, But it is better than the alternative, no battery. It was easy to install I only wish they gave some replacement screws with it because I lost the original ones.
