I left my key on for about two days before I realized it. This obviously drained my battery severly. I called the dealership and they said all i needed was the HD trickle charger. So I bought it and hooked it up last night only to find out that the trickle charger only works if the battery is at a certain level and not drained completly. Called the dealer back and told them what was going on and they said that I need to take the battery our of the bike and take it to them becuase they have a special charger that MIGHT bring the battery back to life, but I will most likely have to buy a new battery. I have a 12volt marine/rv battery charger that I wish I could use to get a little bit of a charge on the battery and they I could use the trickle charge to get it to where it needs to be. Is that sage or should I just take the battery to the dealer.
Any help would be greatly appreciated. I have a 2008 1200 XLC (Sportser Custom)
Thanks

Modern chargers either 10 amp or the under 1 amp maintenance chargers require a reading to charge. I can put my DC volter meter on both and it will show no voltage. My older 10 amp will. The newer ones have a much better voltage control and need a load to charge. They also will not put out if reversed .
If your battery is so low, it will not charger, I bet it's done. I sure would not charge it in the bike. If you really are determined to try, take it out. Take a set of jumper cables and hook the + to + and - to - from your car to it. Leave room for the maintenance charger. Let is sit for a few minutes. Now hook your charger to the the bike battery and remove the connection for the car. It will probably continue to charge.
It's probably damaged pretty bad and I seriously doubt it will full recover. It takes a special built boat type battery for deep cycle. RIP's CRV was about a year old when she left rear door light on about a week. I charged it a few days. It never was right and the green indicator never showed green anymore. It tested OK and voltage was correct. It just did not have the amps it should have had. It did last a couple more years.

OR he's still on the side of the road somewhere cause it failed.
I ran across this thread via Google while searching trickle charging a dead battery. After hearing all these stories, I ran down and bought a Lithium battery. Caught it on sale for 150. It's lite as a feather (not that it really matters on a Fatboy). Hope it's worth a darn.
