There is a misunderstanding here. The Chipolo One contains a battery that, in my experience, lasts 1-2 years. However, the Chipolo does not determine its location and does not transmit it, but can only be "found" by mobile phones with the corresponding app. So you can't actively track the Chipolo's location. At best, you can mark the Chipolo as "lost", in which case the location would be reported back to the owner by every Chipolo app (if someone with the app is in the vicinity of the Chipolo).
