01AV434 Laptop Battery Compatible with Lenovo ThinkPad Yoga 370 X380 Yoga 260 Series SB10K97591 01AV432 SB10K97589 01AV433 SB10K97590 15.2V 51Wh/3355mAh 4-Cells

I have three major "trust issues" with this battery. First, there was no identification at all of the manufacturer or brand name. I know these are all made in China, but the manufacturer or seller will at least put their name on the product. This is truly a "no-name" battery. Second, the battery did not easily fit into the compartment. The battery is supposed to drop right in with all screw holes matching. Not this one. It took a bit of twisting to get it into the compartment and the screw holes did not match. Third, although the battery did power the computer successfully, both the Lenovo Vantage application and another application called Hardware Info showed that this was only a 4400 mWh battery in both design and actual capacity, even though it is marked and advertised as a 5100 mWh battery. False markings on the battery itself was strike three. Note: The original Lenovo battery is 5100 mWh. I have not been able to find anyone selling an actual 5100 mWh battery...all the other sellers market 4400 mWh batteries (they work perfectly fine but don't run quite as long)...but at least they honestly say so.

Just replaced the battery and the new one didn't even get the laptop turned on. The laptop shows not charging and no power. Replaced with the old one and it works fine. Faulty battery.
