Came well packaged with installation instructions. Just needed a Phillips head screwdriver and two minutes. Done. Being a manufacturer direct replacement there was no worry on fit. Let's see if it lasts more than a year.

Good customer service: they confirmed manufacturing date ( March 2022) before I bought it which is important for the battery. Installation is super easy and most importantly it works. It looks like battery comes at least partially charged so I was able to test immediately.The original battery worked for 10 years. I hope this one ( OEM ! ) will last a number of years too.Highly recommend buying this product from this seller
