Left the light and ignitions switch on for about a week. Battery dead...went on two rides hoping it would re-charge, no luck. Tried to jump it...just clicks. Trickle charger says it charged..Do I have a dead cell, or is there possibly another problem? I don't want to drop the $ on a new battery is there is something else going on. Thanks for your help...

Did the same thing, only left it on for a day in very hot weather. I could not get it back. That was three months ago, and I am still on the kicker.

I am not going to replace it until I have time to come up with an automatic low voltage shutoff to prevent it from happening again.

Left mine on and had the same problem. Again, several multi hour rides and the thing did not charge. I then used a 12 volt charger that I bought at target. It had a 2 amp setting which I used. The batter charged in about 5 hours. I have never had a problem since.

Some chargers will not charge a completely dead battery...I know Battery Tenders will not.There are chargers out there that will deep cycle charge which is what you need.

When you let the charge out of a lead-acid battery salt crystals form on the inside. These crystals puncture the insulation material between the anode and cathode plates - they conduct electricity, so they short out a cell at a time.

An old trick, going back to NiCAd batteries is to blast them with current. A good dose of current will melt the crystals and the battery will hold a charge again. A car battery charger can be used for this purpose.

Unfortunately, the holes in the insulation are still there and will leak current through them. In other words - this is only a temporary fix. I had a DRZ that this happened to, after blasting it then charging it with the battery tender - I got another year out of the battery before it had to be replaced.

Good luck,
