Battery works great. Seems to last longer than my son's attention span when driving the car. Just a side note, after doing my research, I thought this was the proper replacement battery for the Lightening McQueen car. It is not. The connector didn't match what was on the car. Being a bit handy I was able to make my own connector for both the car and the battery so it wasn't a big problem. Just make sure that this connector matches the one on your car or truck.
