I purchased this after getting an aftermarket battery. I'll never by aftermarket batteries again. This OEM battery gives me around 10 hours of battery life on my X220 with normal web browsing and about 6 hours with heavy use (depending on the power profile of course). It will add some weight to be expected. You're trading light weight for longevity. If you need a high capacity, OEM battery this is the one. You get what you pay for.

At first I was hesitant because the voltage was showing up as 7.3V which is way off course for a battery that is supposed to be nominally 11.1V but nevertheless after a good charge all the way back up to max it has since performed quite well. X230 i5 with Windows 10 gets about 7-8 hours right now with a light load of web browsing and document editing. Pretty stable battery that I think will last quite a while if maintained properly such as using threshold charging and proper storage if long term storage is in its future. It came sealed in an OEM box that looks straight from the factory. Satisfied with the unit.

This battery is for an older high end laptop that still performs my necessary tasks well. The battery fit perfectly, and charged appropriately. It seems to carry a useful charge, and was priced very well.

Battery works perfectly on my x230. Amazing battery life and still keeps the entire thing feeling pretty light weight. It is an extended battery so it sticks out further in the back, but the laptop is still small enough that it fits in a 13 inch laptop bag even with the battery. Great deal.
