I got this battery for my robot vacuum in August 2022 and now it is December 2022 and the battery is bad. I though you get at least one year out the battery. My old battery, I had it for about four years before it started to go bad. I am using my old battery again and the robot vacuum is working again. I also see that this company doesn't stand behind the product too. I couldn't exchange it. I will not ever buy a batter from this company again.
