OKP Replacement Li ion Battery 12.8V/[****] For Robot K2, K3, K4, K5
The battery was easy to install and works well. Now I am able to use my Robot K2 again.
Great item. Fits perfectly, direct fit. Battery life is as good as original. Definitely much better battery life than my old battery. Nice refresh of my older mop. Now with this new battery my vacuum cover much larger surface area on one charge. Five stars!
