Chipolo PLUS has a 1-year non-replaceable battery and is part of the discounted Chipolo Renew and Recycle program.
The Chipolo PLUS uses a CR2032 battery but is sealed shut to prevent water damage and since the tracker can’t be opened, the battery can’t be replaced once it runs out.
The Chipolo PLUS is a discontinued product, but the Renewal Program 50% discount can be used to purchase any current Chipolo product available, to always keep you protected.
