UPDATE: Seller reached out and sent a replacement part 2 days later. Replacement part seems to be working well so far even though the manufacturing date is also October-2021. Hope it will work well for couple of years. Due to the excellent customer service changing the rating back to 4 stars.-----------------------------------------The installations was easy. The manufacturing date was October-2021 so I was suspicious.After the first cycle of charging and discharging it is not holding charge at all. When I unplug the laptop from the charger it dies immediately so returning it.
