What is Battery Voltage? Why the Voltage of Your Battery Matters
The constraints of low voltage include increased current at a low power factor, causing a greater voltage drop, increased propagation delay in logic circuits and subpar appliance performance. These limitations can lead to decreased efficiency and reliability in your devices, if they do not in fact destroy the device entirely.
