93 seca ii Died

[bkizer08]

So on my way home from work a couple weeks ago as i grab the clutch to down shift and slow down for a red light my bike died on me. I kept cranking the bike and finally got it started agian, but this time the power wasnt there, it was bogged out bad. When i went to stop at the next light i had the same problem. The bike died and this time wouldnt start back up. I trailered it home and threw a charger on the battery the other day to get to work on the bike. I tried starting it after the battery charged and it acts as if it didnt even get charged. So would you say my battery is bad or is it something else? And also what may have caused the bike to die in the first place?
