A wall clock draws a very small, constant current to drive the quartz movement. The load is steady, with no peaks or pulses. The battery must deliver energy efficiently over an extended period — often 12 months or more.
Because the current draw is small and constant, low-drain behavior becomes an important discussion point. Product selection should be confirmed against the device's actual load requirements and validated data.
This is a Power Profile recommendation based on load characteristics — not a specific SKU confirmation.
Based on this application's load profile, the recommended product direction is:
