ASODIL18L4P71 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.

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

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!

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:)

My aunt gave us a laptop that wouldn’t take a charge. We relate the old battery with this new one. Same size, but higher capacity.We found out that the charger was bad, so we ordered a new charger.My sun swapped the old battery back in for testing. The new battery provides about an extra hour over the old one!

I suppose some of the credit should go to Lenovo for making a laptop that can be owner serviced. But these guys put enough information in the listing to give the confidence to proceed. The price was good, the information for ordering the correct battery was spot on, and the battery even came with the screwdrivers I needed. Saved a ton of money and a trip to the nearest city for service. Two weeks in: the battery seems strong and holds a charge for hours.

The unit was purchased in Sept, 2023, because it had the exact specifications as the existing OEM batteryinstalled in the laptop. It shows at100% full in the lower taskbar, but does not hold a charge. As of now, Jan, 2024, the laptop will not work unless it is plugged into an electrical outlet. The laptop shuts down immediately when unplugged, and will boot up when plugged back in.********* WARNING - DO NOT BUY THIS REPLACEMENT BATTERY *********
