Good morning Dave,
I would suggest contacting the charger manufacturer if you do not currently own this model charger. The only listed TecMate manufactured charger that is approved (tested) by EnerSys/ODYSSEY is the Accumate 7A 12V-7A-S which will full charge and maintain the ODYSSEY PC680 battery and meets the following requirement's
1) 3-step charging profile
2) Absorption charge voltage between 14.2-14.8V required with 14.4-14.8 being recommended
3) Constant Float voltage between 13.5-13.8V required with 13.6V being optimum
4) Never exceeds a constant voltage of 15.0V in any kind of automatic reconditioning/equalize/de-sulphation mode.
5) For cyclic (deep discharge) applications a minimum charging current of 40% of the 10 hour amp hour rating of the battery is required. The minimum recommended charging current for a PC680 at 16Ah rating would be 6A.
If the charger meets these requirements I would also recommend a minimum of 8 hours in float mode to ensure that the battery is fully charged as many chargers go into float mode prematurely for the ODYSSEY battery therefore the battery is not truly fully charged at that point, even if the charger indicates so. Any ODYSSEY battery can be left on float indefinitely with a Float voltage between 13.5-13.8V without harming the battery.
I hope this helps. Please contact me if you have any further questions or concerns.
Sincerely,
Kathy Mitchell
