Keeping a battery in the refrigerator is an old "wise tale". It actualy does more harm than good. The best way to use a rechargeable battery is to keep using it through its normal working cycles.
In any case, the maximum life span of a rechargeable battery will be about 3 to 5 years, or about a thousand charge cyles no matter what. leaving a rechareable battery discharged is also not healthy for it. The chemcicals inside the makeup of the battery will eventualy eat away at the inner construction, and maybe cause some oxidiation on the contact surfaces of what the battery is made out of, and they too will also degrade with age.
If a battery is allowed to be frozen, such as putting it in the freezer, it can be permanently damaged. Lead acid batteries in the discharged state will be quickly damaged in sub-zero conditions.
I would suggest to use the battery and to not let it be in the discharged state for very long.
