Charging When the Doorbell Is Installed on the Wall

When the doorbell is installed on a wall, there are three convenient ways to power the device: battery-only, via mechanical/digital chime, and using a power adapter.

Regardless of the chosen method, the battery must be charged before being used to power the doorbell.

  1. Battery-Only: In this method, the doorbell operates solely on battery power, eliminating the need for an external power source, and offering convenience.
  2. Mechanical/Digital Chime: When powered via a mechanical or digital chime, the device's battery is trickle-charged.
  3. DC 24V Power Adapter: Using a DC 24V power adapter also trickle-charges the device's battery.

Note: Trickle charging helps compensate for battery capacity loss due to self-discharge.

During the later stages of charging, particularly when the battery is nearing full capacity, charging it with a lower current helps maintain the battery's charge status and reduces the impact of self-discharge. Although the battery indicator may show 100% charge, it may not be in a fully saturated state. This trickle-charging phase typically requires an additional 30-40 minutes to ensure the battery reaches optimal charging status.

Charging When the Doorbell Is Not Installed

If the doorbell is not yet installed, you can charge the battery using a DC 5V 2A adapter (Type C). Most smartphone Type-C adapters meet this specification and can be used to charge the doorbell battery.
