It comes with a battery installed, ready to use. I would save the instructions for a new battery purchase when the time comes. Since you turn the battery on and off for use, it should last a long time.

It does come with a battery, however the instructions that come with the collar tell you that the initial battery probably will not last as long as the replacement batteries. We purchased a replacement battery when we bought the collar based on the recommendations from the reviews we have read just so that we weren't stuck without one at an inopportune time. We've only had the collar for a week, but the initial battery definitely has juice left! I hope this helps!...even though this question was asked 10 months ago. :0)
