I was looking for a battery that I can always know it is ready to go. Thats why I decided to try this one out. It provides enough power to clean my apartment really well. I don’t have to deal with a lot of pet hair but I am glad this one takes care of the task really well. I have it ready to go inside my food pantry for every day use after every meal. I would say this was a good purchase. One plus for me is that it is light enough to carry and powerful enough to clean my place.
