It is best not to store them at -80 for too long, they will degrade and any cells you get out of a tube older than about a year are quite likely to be different to the population you put in there. If you need to store them at -80, make sure you get them up every 6 months of so and re-freeze them to ensure that they are as similar to the original population as possible.
