How Many Volts Is a C Battery-Introduction and Measurement
C Batteries are also fondly referred to as R14 batteries. It is the regular size of dry cell batteries that are used for medium range applications such as toys, musical instruments and flashlights. According to a report that was published around 2007, these batteries account for about 4% of all the alkaline batteries that was used in the U.S. over a period of time. While a C battery usually comes with a nominal 1.5V, the actual voltage will depend on a number of factors. Capacity and voltage are some of those factors. There are many more things you probably need to know about a C battery other than the surface 1.5V you’ve known it to have.
How many volts is a 9 volt battery?Apparently, this sounds like a bizarre question because you would expect a 9V battery to be nine volts, and nothing more! But there is more than meets the eyes when you are trying to know the voltage capacity of a battery. Yes, the voltage of the said battery may not be far from 9V, the real voltage will depend on the battery chemistry and the amount of power left inside of it.
Battery voltage testing
To get the actual voltage reading of any battery, you need to test the battery with a voltmeter or any voltage reading device that you are aware of. Follow these steps to test the battery with an ohmmeter;
Have the black colored lead connected to the part of the meter that is marked ‘COM’.
Have the red colored lead connected to the multi-meter part has V written against it.
Since you intend to test for voltage, adjust the multi-meter dial to the DCV or V setting. You need to be very precise with this, otherwise every reading you get will be wrong.
If the meter you are working with has a manual range of voltage values, try setting it at a value that is above 9V. But if you are using a multi-meter with an auto-ranging options, you wouldn’t need any of that since the meter would automatically pick the voltage range.
It is what it is. What you see on the meter would be what your battery is capable of. The initial 9V is just a name tag. If the battery is by any means faulty, it will hardly deliver up to 9V. So try and always read the battery to know its strength terms of voltage.
Does 2 1.5 volt batteries equal 3 volts?Two 1.5V batteries can amount to 3V if they are connected serially. That is the negative of one will be connected to the positive terminal of another one. Even most batteries that are more than 9V are simply achieved by arranging a number of 1.5V cells inside the battery. But again, it all depends on a number of factors. The value we just gave you was based on ideal conditions. For obvious reasons, we know that achieving ideal conditions in a battery is not always feasible.
In that case, the serial connection of two 1.5V batteries may not necessarily amount to 3V because some of the voltages may have been lost process.
And in other scenarios, a battery might be rated as a 1.5V when it does not deliver up to that. A good example are some alkaline rechargeable batteries that output a maximum of 1.2 volts even though they are rated as 1.5V.
There is also a parallel kind of battery connection. So when you connect two 1.5V batteries in a particular circuit, you should not expect to have 3V because that will not happen. In general, while batteries are connected in series to attain higher voltage values, batteries are connected in parallel to attain higher capacitance values.
So what if you have 1.5V and a 9V in the same circuit will the same amount of current flow through them? To understand that question, you need to understand the implication of a series and parallel connection. For a series connection, the amount of current flowing through the circuit has to be the same irrespective of the points in the circuit. Whether it is a 9V or 1.5V battery, the current passing at any point in time would be the same. Always have that in mind.
How many volts is a car battery?Sounds like a straightforward question that would require a straight answer, right? You bet! When checking out the voltage coming out of a car battery, there are three category of readings you ought to be expecting. They are the normal, excess, and bad voltage readings.
When your car battery is okay, you can expect it to read up to 12.4V or even as high as 12.8V. Anything in between that range of voltage can be considered as the voltage of a proper functioning battery.
In other instances, the battery may peak above 12.8V, and give you something like 12.9V or more. That is simply an indication that you are having excess voltage inside the battery. Well, I’m not sure if that is something that should give you a cause for alarm. Another thing you can do about it is disconnecting the battery from the load for a little while, with the hopes that it will discharge some of those excess voltages.
The last set of voltage reading you can get from your car battery is when the battery needs to be replaced or refurbished. When it reads lower than 12.4V, you should start warming up for the necessary changes. But if it starts to read something like 11.4V, you know it is time up for that battery. That is almost an irreparable case.
SummaryThis post has been able to touch on a variety of topics related to battery voltage. And frankly, we have given you as much information as we have. Voltage testing is very good as it helps you to stop speculating about the actual voltage your battery is producing.
