This July I left my lights on and ended up having some friends who work on bikes and motorcycles all the time jump start it with a battery pack. I had never used one but after I learned this can be a really bad idea. Anyway, since then whenever I put my battery on a trickle charger it shows that it is already charged even when I know it isn't. For example, I had a few weeks where I couldn't ride so before I went for a ride I put in on the battery tender and in less than a minute it showed the battery "fully charged." Nevertheless, when I tried to start it up, the battery was a bit dim and it took awhile to turn over. Since I got a new job, it has made riding or commuting almost impossible, so today after not riding much for about a month, I tried to start my bike and it was very dim and I couldn't get it to turn over and then it just went completely dead. Not ever a dim light. Nada. So, I put it on the charger and it was supposedly fully charged in about thirty seconds. Tomorrow I am going to get a new battery but could this be something much worse? While recently I haven't been able to ride much, I was able to ride about 1000 miles on it since I had to jump it. Could I have fried my alternator or something else? Like I said, I was able to put on a good deal of miles without issue. It would make sense that it might be dead, however, it doesn't make sense why the battery tender is showing that it is full.
