I purchased the 'pivot' black and decker off amazon about a year ago. It's good for cleaning the car, crumbs, quick pick ups. The battery lasts about 15 mins of straight use, but I only ever drain the battery when cleaning the car. I really like mine as a supplement to the big vacuum. It's designed well, the battery works, and it is a great tool for around the house. Also, cleaning the filter is easy, you just take it apart, wash it, and let it dry. The one you have a link to is pretty much the same thing so I'm sure it's just as good, maybe slightly less effective if it doesn't have the brush attachment.

It sounds like the battery has worn out and won't hold a charge anymore. Batteries across all brands wear out in 3-5 years and sooner for cheaper vacuum. Unfortunately, there's nothing you can do to fix this, the battery is internal and not replaceable. Theoretically, if you could open up the vacuum and find a replacement battery you could replace it but many cheaper vacuums are not made to be opened, and opening them would break parts of the vacuum.
