I've got a spare battery sitting here that I don't need right now. I was planning on packing it up and putting it away. I remember hearing that rechargeable batteries go bad if electrons aren't regularly flowing through them (charge and discharge cycles.) Will I be destroying the battery short if I end up leaving it on a shelf for a few years?
How long do ego batterlies last if unused?

Lithium-Ion
The possible storage temperature range for Lithium-Ion batteries is is -20°C to 60°C but for prolonged storage period -20°C to 25°C is recommended and 15°C is ideal. Cells should be stored with a partial charge of between 30% and 50%. Although the cells can be stored fully discharged the cell voltage should not drop below 2.0 Volts per cell and cells should be topped up to prevent over-discharge. The maximum voltage should not exceed 4.1 Volts
If secondary cells must be for a prolonged period the state of charge should be checked regularly and provision should be made for recharging the cells before the cell voltage drops below the recommended minimum after which the cells suffer irreparable deterioration.

Here's the reply I received from Joyetech:
Yes. It should be noted that the cell would be an over-discharged state by its self-discharge characteristics in case the cell is not used for long time. Over-discharging may causes loss of cell performance, characteristics, or battery functions. In order to prevent over-discharging, the cell shall be charged periodically to maintain between 3.7v and 3.9v.

I got a follow up email from Joyetech saying that if batteries are left unused, they should be recharged every two weeks.
