I was a little concerned about using a standard battery charger with the Odyssey PC680 battery since I have read that the battery could be damaged by a normal charger. I did find a few less expensive chargers that were recommended for maintaining the Odyssey series of batteries, but were not recommended for charging them. I found a local dealer who stocked the OMAX-6A-1B charger that was made for the Odyssey batteries. If you can't find one in your area, Allied Batteries in Seattle stocks them. I paid $75.00 for the 6 amp model.
