4 Channel 24V Relay Module Solid State High Level SSR DC Control 250V 2A with Resistive 500mm Smooth Rod This is the 12V relay

This is the 12V relay most commonly used switching device in electronics

insert the plug straight into the receptacle and rotate clockwise until you feel positive mechanical engagement and hear an audible click

This change in resistance is converted into an analog voltage signal through a simple voltage divider circuit with a load resistor

How should I store this battery safely
