The video above shows how I fixed the Black and Decker battery not charging issue.
First, you would need another battery with similar or around the same voltage with the faulty battery.
After that, connect the Positive terminal of the battery to the Positive terminal of another battery.
Also, the Negative terminal of the battery to the Negative terminal of the another battery.
Let it stay connected for few seconds, and now the battery should have been resetted successfully.
