Raspberry Pi 5 RTC battery

The power management IC used on the Raspberry Pi 5 incorporates a real-time clock and a charging circuit for a button cell that can power the clock when the main power supply is disconnected.

The Panasonic ML-2020 Lithium Manganese Dioxide rechargeable battery has a two-pin connector suitable for connecting to the battery connector on the Raspberry Pi 5's PCB, and a double-sided adhesive pad for attaching it to the inside of a case or other convenient location.

A long-awaited feature that will help maintain an accurate and reliable time reference, which is particularly useful in various IoT projects where time synchronization is important. The real-time clock helps make your Raspberry Pi 5 more self-sufficient and ensures accurate time stamps and time-based operations.

Ideal for triggering alarms at specific times, recording data, creating events...
