This handy additional battery for your WV5 Window Vac allows you to get up to 1 hour and 10 minutes of uninterrupted cleaning time when using two batteries. Simply unclick the battery from your window vac and click the second battery in place. Then you are ready to go again. This additional battery works very well with the WV5 charging station, as it allows you to store and charge both your window vac and the spare battery.
