Solved: CMOS battery voltage
A new battery has a voltage of 3V, what I''m wondering is, if the voltage is reading less than 3V on my multimeter (e.g. 2.93V) does that mean the battery is going flat and won''t keep accurate time, or will the timekeeping only be affected if the voltage drops below a certain level, e.g. 2V?

What are car battery voltage charts?
Car battery voltage charts provide valuable information about the voltage levels of different types of batteries at various states of charge (SOC). These charts are essential for understanding the voltage characteristics of batteries and help monitor, manage, and optimise battery usage.
What is charge voltage?
Charge Voltage – the amount of battery voltage when the battery is fully charged or the voltage available at any given point during the charging process. Various sources describe charge voltage in two different ways, so we’ll cover both here. The voltage of a battery gradually decreases as it discharges
What is battery voltage?
Battery voltage refers to the measure of electrical potential difference between the positive and negative terminals of a battery. It indicates the amount of electrical energy stored within the battery and determines the force with which electrons flow through an electrical circuit when the battery is connected to a load.
What is a normal battery voltage?
We noted that 12.6-12.7 Volts is the normally voltage for a fully charged battery, and showed which voltages correspond to which approximate charge % level. Be aware with analysing voltage – it doesn’t show the health of the battery per se, it just shows how much charge is in the battery at the moment you measure.
What happens if a battery reaches 0.8 volts?
The voltage gradually decreases as the battery is used. When the voltage drops below 1.0 volts, most devices will consider the battery depleted. However, some low-power devices can continue to function until the voltage reaches 0.8 volts. A voltage chart helps users estimate remaining battery life.
How many volts is a fresh alkaline battery?
A fresh alkaline battery can have an open-circuit voltage of up to 1.6 volts. The voltage gradually decreases as the battery is used. When the voltage drops below 1.0 volts, most devices will consider the battery depleted. However, some low-power devices can continue to function until the voltage reaches 0.8 volts.
