What Homer said.
It would be worth letting us know what voltage rating the charger you used was, along with the voltage rating of the battery itself. There should be a series of numbers on the label, just take a photo if you aren't sure which are the correct digits.
Lithium-ion batteries are tricky little buggers. Too low of a voltage going in, catastrophe. Too much of a voltage going in, catastrophe. Particularly the higher voltages can be incredibly dangerous.
They're charged by what's called "trickle charging" which is exactly what it sounds like. Think of a coffee maker - it might drip one drop at a time, but it's steady and consistent. What would happen if you forced more pressure through the tiny little hole into the pot? Well, you'd end up with an explosion, of sorts (coffee all up in your face
).
With the coffee maker analogy in mind, try to picture that happening with a battery. They're only meant to handle so much at a time. Too much, and you can have a big problem. You could possibly even burn your house down.
As was suggested, try it with another battery and go from there. It definitely sounds like it's a fried battery. Make sure though, that the batteries are either identical, or have identical voltage ratings (the numbers on the label should match).
