To determine if you have a Tracker with a replaceable battery or not please consult this article.
The battery used in your Tracker is a common coin cell battery, type CR2032.
If the LED on your Tracker is blinking red or if your Tracker's LED is rapidly blinking blue this indicates a low battery.
Important note: Please pay attention to how the battery was positioned when you remove it and make sure you insert the new one in the same way. When the button is on the left of the Tracker the battery must be inserted with the + side facing up. If you insert it the other way around, it might discharge.
Below is a short video showing you how to remove the battery in 4 different ways:
