I have a Odyssey PC680MJ and my car has been down for a month and forgot to disconnect my battery or hook it up to a tender. I tried to see if my car would turn on and the battery seems completely dead. How do i charge this battery? Can i hook up a spare battery i have start the car then hook up the odyssey and let it charge when the car is on? Or hook it up to a charger and let it charge?

 

I did a quick search for 'Odyssee PC680 charging', and found the following info. http://www.odysseybattery.com/docume...gedODYSSEY.pdf. Also, I believe that the PC680 is an AGM battery, so if your battery charger has a setting for AGM, then select that. - Jim

 

They sell a charger for them it works pretty good.I have destroyed three of the pc680's over the last three years by letting them get too low and then they don't hold a charge so my advice would be to try not to do that if possible in the future.

 

Battery tender all the time.
