They should be OK, but why don't you pull the battery out of your laptop and google for its model number to see if there are any for sale. This would give you an idea of the price for a new new battery. You can then decide whether or not to go for one of these batteries that have been sitting on a shelf for an unknown period of time.
Once you have the price for a new battery, if you decide to go for one of these on the shelf ones, I suggest you negotiate a discount for age and an agreement that if the battery doesn't take and hold a charge you will be entitled to a refund. It's the tight fisted Scots git in me coming out !

You might need to recalibrate your laptop for the new battery. You can easily recalibrate your laptop properly via the Windows Power Management.

What type of battery chemistry is it? If it's Lithium Ion, they deteriorate simply with time, as well as usage cycles, so it's best if you can confirm a manufacturing date to see that a new one hasn't used up too much of its shelf life. If it's old enough to be NiMH, the total lifespan is determined more by cycle count that actual age, but they self-discharge quickly and have their life shortened by deep cycling, so a new one should be given a good long charge before being used and you should watch how it holds up early in its life to avoid running it flat.
