Car Battery Voltage Chart: A Guide to Your Vehicle''s Electrical …
It is important to note that the voltage of a car battery can vary depending on several factors. These factors include the age of the battery, the temperature, and the level of charge. For instance, a weak battery may have a voltage reading of less than 12.2 volts, while a fully charged battery may have a voltage reading of up to 12.8 volts.
19.2: Electric Current
Voltage is the energy per unit charge. Thus a motorcycle battery and a car battery can both have the same voltage (more precisely, the same potential difference between battery terminals), yet one stores much more energy than the other. The car battery can move more charge than the motorcycle battery, although both are 12V batteries.

Rechargeable Batteries explained in detail (NiMH, NiZn, NiCd, …
Voltage. NiZn''s have the highest initial voltage of any rechargeable AA or AAA battery. The nominal voltage is 1.65, and fresh out of the charger the voltage is as high as 1.85V. (PowerGenix, PDF, and my tests) This is way higher than the 1.5V for alkalines. The higher voltage can be both a blessing and a curse.

How to Diagnose a Bad Car Battery – Practical Mechanic
Ultimately we will need more information than just the battery voltage to tell us if the battery is bad. You will need to know the battery''s ability to deliver amperage to the starter motor. That being said, voltage can be a good start for diagnosing! ... A fully charged car battery will have a voltage of 12.6 volts when the car is off. A ...
Intro Lab
Project Overview. In this project, you will learn how to use a voltmeter to measure voltage. Typically, the voltmeter is one of the functions of a multimeter, which is an electrical instrument capable of measuring voltage, current, and resistance (Figure 1).. Figure 1. Digital and analog multimeters with test probes connected to measure voltage.
A Guide to Understanding Battery Specifications
• Terminal Voltage (V) – The voltage between the battery terminals with load applied. Terminal voltage varies with SOC and discharge/charge current. • Open-circuit voltage (V) – The voltage between the battery terminals with no load applied. The open-circuit voltage depends on the battery state of charge, increasing with state of charge.
