Product Overview
I recently purchased the Powerextra 4.0Ah 14.4V Replacement Battery Compatible with Roomba R3 500 600 700 800 900 Series for my vacuum cleaner and I am very pleased with my purchase so far. This battery is designed to fit the Roomba R3 500, 600, 700, 800 and 900 series models. It is made from NiMH and has a capacity of 4000mAh. The installation was very easy and it fits my Roomba perfectly.
I have been using this battery for several weeks now and it has worked great. I have noticed that it holds a charge longer than my previous battery did and I dont need to recharge as often as before. It also charges quickly which is great when Im in a hurry to use the vacuum cleaner. The product comes with four side brushes as well as two screws as an added bonus which is really nice.
