How to Charge the Battery of Your Tapo Smart Door Lock: Charging Steps and Battery Status

TP-Link Tapo smart door locks use a rechargeable battery charged via USB-C. Depending on the model, the battery can either be removed from the lock for charging or charged while still installed.

This guide provides the battery charging steps and explains the Battery LED indicators, so you can monitor charge status. After reinserting the battery, you may need to sync the lock's time via the Tapo app, especially if the lock is not connected to Wi-Fi. If you haven't set up your lock yet, see how to set up your Tapo Smart Door Lock first.

Key Takeaways

• Tapo smart door lock batteries are charged by connecting the included USB-C cable to a 5V USB adapter (sold separately).
• For best charging performance, a 5V/2A adapter is recommended.
• Some models support charging while in use. For in-use charging, plug the USB cable directly into the Type-C port of a battery pack with 5V/2A or higher.
• During charging, the Battery LED shows solid amber. When fully charged, it turns solid green.
• After reinserting the battery, open the Tapo app and connect to the lock to sync the time, to ensure scheduled PIN codes will take effect.

Charging a Tapo Smart Door Lock Battery

Step 1. Remove the battery cover of the interior assembly

Step 2. Take out the battery and Charge it

Plug the provided USB cable into the battery's Type-C port, then connect it to a power outlet using a USB adapter with a 5V output. If your door lock supports charging while in use, the battery does not need to be removed. Just plug the provided USB cable into the battery pack's Type-C port, then connect it to a power outlet via a USB adapter with a 5V/2A (or higher) output.

Battery LED Indication:

• Charging: Solid amber
• Fully charged: Solid green

Notes:

1. Charging will take a few hours. It is recommended to use a 5V/2A adapter for the best charging performance.

2. The USB adapter is not provided.

Step 3. Insert the Battery and Sync the Time

Insert the battery into the interior assembly after charging if you have taken it out. If the lock is not connected to a Wi-Fi network, open the Tapo app and connect your phone to the lock each time you reinsert the battery to sync the time.

Note: If the lock is not connected to a Wi-Fi network after the battery is reinstalled, the lock's local time will not sync automatically. This means scheduled PIN codes will not take effect until you open the Tapo app and connect to the lock to retrieve the correct time.

Q & A

Q1: Why Does My Tapo Smart Door Lock Battery Always Show 100% in the App?

This is an expected behavior. The smart lock has a reserve battery capacity beyond the displayed percentage. The reading will stay at 100% for a long time as this additional buffer power is depleted. Only after this reserve is used up will the displayed level begin to decrease gradually.
