    Get an automatic charger with a deep cycle charging feature or charge until they are showing at least 12.5 volts on a meter.

    Odyssey AGM type batteries?

    Unless they are really old, they should hold a charge for more than six weeks. My Deka ETX16LM batteries sat all winter, and still had about 65% charge remaining.

    A 2 Amp charger would take less than 10 hours to put a healthy charge into them.

    AGM batteries need a slightly different charge cycle than regular lead-acid batteries. If you have a charger with an AGM setting, that is best.
