It is best to fully charge a battery and store it with a float charge,, assuming you have a way to do a proper float charge. (How are you proposing to, as you say, "charge it every day?"
There is an optimum (compromise) point that keeps the negative plate from sulfating too much and the positive grid from oxidizing too much. Too high a float voltage accelerates positive grid corrosion, too low a float voltage results in gradual sulfation of negative plates.
being we are talking agms you may get away with the 2 month periods without a float charge to it. i still don't recommend it and i disagree totally with storing agms without a charge to them for 4-6 months because sulfation will still occur and it just does not occur only when below 80% soc.
