Battery voltage is critical to the proper functioning of your device. the typical discharge termination voltage for a CR2032 coin cell is 2.0V, in fact, many devices may not function properly when the battery voltage drops below 2.5V. Different types of coin cell batteries have different voltage requirements.
Rechargeable coin cell batteries such as the LIR and ML/VL series have typical voltages of 3.6V and 3V, while those that are not rechargeable, such as the CR series of 3V lithium-manganese button cell batteries and the LR/SR series of 1.5V alkaline zinc-manganese batteries, have relatively low minimum operating voltages. Rechargeable batteries are suitable for applications that require continuous power supply, while non-rechargeable batteries are suitable for disposable or low-drain devices.
Button batteries are widely used in miniature electronic products such as computer motherboards, electronic watches, electronic dictionaries, electronic scales, remote controls, toys, and even medical devices such as pacemakers and hearing aids due to their compact size. Batteries have a complex internal structure, including components such as anode, cathode, and electrolyte, and common types include silver oxide, lithium, and alkaline manganese batteries.
Overall, it's critical to know the minimum voltage your device requires and the type of button cell you're using in order to ensure proper operation. In the event that the battery voltage falls below the recommended minimum operating voltage, you should consider replacing the battery in order to maintain proper function of your device.
