This depends on how many positioning updates you demand from the tracker. You can control how your device should behave through the BikeFinder app. 


The app has four different settings for your BikeFinder tracker: Standard, Security, Tracking, Passive.
The battery life varies for each setting and it could also depend on the variations in temperature and use of the tracker.

This means that the more GPS positions the tracker is sending, the more battery it is using.

Highlights:

- In Passive mode: The battery can last up to 8 weeks (Not eligible/qualified for insurance)

In normal use in Standard & Security mode: The battery can last 2 weeks (Must be used if you buy with insurance)

- For searching a lost bike in Tracking mode: The battery can last up to 16 hours 
(Use Security mode to save battery when not actively searching for the bike)

The BikeFinder tracker has a long battery life in order to work as a security device in case of theft.
Therefore it is not possible to request the position of your tracker in the BikeFinder app, because it would require the tracker to constantly be in connection to the internet, which would make the battery run out very quickly.
