I agree with Illusion...moving 8D's isn't my idea of fun!
Anyway, to protect your investment you will want to keep that battery
fully charged as best you can. Flooded batteries have a pretty high self-discharge rate, and can lose a lot of their charge in just a few weeks. You DO NOT want this to happen.
When lead-acid batteries are at less than a full-charge state, lead phosphate crystals (PbSO4) begin to form on the plates. Over time, these will reduce the capacity of the battery, i.e., it's ability to store and deliver energy. Some other things also can happen when a battery is stored, like stratification wherein the electrolyte begins to separate into layers so that the plates don't receive equal treatment.
Occasionally, it's also a good idea to give them an equalizing charge, i.e., a controlled over-charge using 15.5-17 volts or so for a few hours. This helps restore equilibrium amongst the cells, and helps to knock off the PbSO4 crystals. See the battery manufacturer's recommendations.
