Bad product. The battery that I received clearly was an old battery: old scratched label. The charge lasts even less than the battery that I replaced. Bad product.

Very good price and delivery Very good price and delivery, and the battery holds a much better charge than the OEM battery. Used to get two and a half hours, now I get close to four hours with the new battery.

Battery works, some Windows 10 battery status issues After just installing the battery it seems to work. I'm using a windows 10 operating system. The battery icon doesn't recognize the battery however after unplugging the cord the computer is still running -yay! I've tried troubleshooting and updating drivers but I still don't have a status for how charged my battery is from the laptop. It would be good if lenovobatt could address operating system work arounds to have this error resolve or acknowledge that this software issue cannot be resolved. I'm aiming to dualboot to linux and hopefully there error will go away on the other operating system, but a workaround for windows 10 would be appreciated. For now I'm offering a 4/5 +- depending on the next month performance.

Battery shipped quickly via USPS Battery shipped quickly via USPS. Fit well, powered up immediately and has worked so far. I appreciated they included mini screw drivers in the package so I didn't have to go scrambling to find some. 5 stars at this point.

The new battery will not charge The new battery will not charge. The charger and operating system test good. The battery charge did not increase at all after 48 hours connected to the charger. Support was terrible. They requested photos, videos, and then told me I need to "fully charge (more than 12 hours) and discharge it to 5%-10% for 3~5 times ... before use." This after I told them that it would not charge at all.
