How do you charge a Fitbit Zip? The short answer is that you do not charge it at all: the Fitbit Zip is not a rechargeable device and instead uses a replaceable coin cell battery, so the only way to power it is to install a fresh battery.
What powers the Fitbit Zip instead of charging
The Fitbit Zip runs on a CR2025 coin cell battery, not a rechargeable internal battery. One of these batteries is included in the package with your device. The tracker is designed so that you replace the battery when it runs out, rather than plugging it in to recharge.
How to replace the battery in your Fitbit Zip
- Use the battery door tool that came with your Fitbit Zip to unlock the battery door.
- Remove the battery door from the device.
- Insert the supplied battery with the “+” sign facing up.
- Replace the battery door and turn it clockwise until it locks into place.
Make sure the arrow on the door lines up with the lock icon before you use the tracker. Clean the charging port (or battery contacts) regularly using a soft, dry cloth to ensure a reliable connection.
What the USB dongle is actually for
The wireless sync USB dongle that comes with your Fitbit Zip is for syncing data and performing the initial setup with a computer. It is not a charging cable or charger. The device does not charge through any USB connection, dock, or cradle.
What to do after inserting a new battery
Once you insert the battery, the display appears and stays on for 30 minutes so you can begin setup. The display stays on for 30 minutes after battery insertion so setup can begin. Connect the wireless sync USB dongle to a computer USB port and follow the instructions in the Fitbit app to sync your tracker.
For ongoing power management, you can check your Fitbit battery and power settings in the Fitbit app to monitor battery life and adjust power controls, but remember that the Zip itself cannot be recharged through the app or any cable.

How do I know the battery is working?
After you insert the battery and lock the door, the display turns on and stays visible for 30 minutes.
