ASODI L18L4P71 L18M4P72 Laptop Battery Compatible with Lenovo ThinkPad X1 Yoga 4th 5th Gen / X1 Carbon 7th 8th Gen Series 02DL004 SB10K97642 02DL005 SB10K97643 02DL006 L18C4P71 SB10K97644 51Wh

I ordered the battery as a replacement for the one in my Lenovo laptop. I had already gotten into where my battery was and took a photo of the data, so I was sure this battery would fit, and it did. The package even came with some small, fine, screwdrivers to use for the removal and replacement. Nice. There was documentation on how to proceed, with cautions on how to use it after installation. Everything went smoothly and I know have a laptop that I don't have to keep plugged in all the time anymore. Hopefully it will last for quite a while. Looks like, if I follow the instruction cautions, it will.

I bought this battery for my Lenovo Extreme X1 Gen 3 laptop after the original battery failed. Installation was super easy (less than 5 mins) and it came with a screw driver set which was all I needed to replace the battery. It has been 2 weeks and no issues so far. It holds charge as well as the original battery and changes at the same rate. I am happy with my purchase:)

Started out fine, now won't take a charge and laptop is completely dead. Should have listened to the one star reviews. This is junk.

My Lenova ThinkPad X1 Carbon 7th Gen battery was dead. This replacement worked perfectly! It shipped and arrived with 2 days of ordering. The product description was very clear in that I was able to verify the exact Model and FRU P/N of my existing battery to the one I ordered. The package arrived and included 2 screw drivers and a plastic pic that I used to pop off the battery connector without damaging anything. The battery was at 95% when I installed and has been running on the battery all day. Instructions for when to re-charge are very clear and I plan to follow it to the letter to ensure long battery life. Its a perfect replacement!

It works great, easy installation. A lot better than spending hundreds of dollars for a new one.

Beware of this selling. The battery was delivered and does work, although it isn't preforming well. I followed the directions for installing and charging and found the battery will only last for about two hours. The old original battery lasted for about an hour. Not much of an improvement.I did send a message to the seller about my problem and never heard back. My fault for not starting that process sooner. My 30 days return window expired.

I watched 4 videos on how to replace the battery in the Lenovo X390. In all videos the interior of the laptop looked different. In my case the battery connection was what didn't fit. Also, the battery is slightly larger than the existing (though I think it would have worked), and only one of the holes for the screws lined up. Too bad. On the bright side, after removing and reinstalling the old battery it started charging again and has been working fine ever since.

Installed in ThinkPad. Works as expected. Sadly, I think the ThinkPad was the problem before, not the battery
