Why when we connected two batteries with different values in parallel they are damage?? Can you make a video on this case ??
Isn't a *battery* a collection of cells?
So, essentially you are describing a battery.
I'm not sure if terminology is different where you are, but here in the US we have AAA, AA, C & D cells of ~1.5V and a 9V battery made of six tiny cells inside a rectangular case.
@@jimurrata6785 no no i mean if i have 1.5 v battery and 9 v battery and connected them in parallel what is happen??
@@modarelmohandis1174 1.5V is a single cell.
If you were to try and parallel it with six 1.5V cells in series (9V battery) the battery would try to equalize voltage with that one cell, causing it to overheat and rupture.
You can only add it in series with 9V to create 10.5V.
You can combine cells in parallel or series (or both) but the final configuration of modules must be balanced for voltage and amperage.
@@jimurrata6785 thanks , but can you send the last part of your massage again 😅
I'm a UPS tech, and I love these kinds of videos. Makes it really easy to explain to customers how their systems work without getting into too much confusing theory. Straight forward and simple is always best!
Reminds me of the expression "The candle that burns twice as bright lasts half as long."
"and you have burned so very, very brightly, Roy"
I never heard it explained like this. Makes it much easier to understand.
An awesome overview of issues attached to battery usage... Thanks for putting this together in one place!
Yep learned this when I was 14 a 15..
I loved it.
Nice video
@@asbestosfibers1325 Proof you had fibers.
I learned it at 17 That's because I had a nicotine addiction and got into vaping
Thank you so much Sir.Your videos removed all my confusions.
Theorists be like: A 2500 mAh battery can provide a current of 900 amps for 1 seconds.
Don’t try this at home. But if you ignore this advice, record it and put it on UA-cam 😅
Wouldn’t it be 9,000 amps for 1 second?
@@nicholasdowns3502 yes, miscalculation on my part
@@TheDeadKingsRaven I can't tell if you are serious or not, but in case you are:
You can't actually output that much current from the battery. The reason is the internal resistance of the battery.
If we assume the battery has an internal resistance of for example 5 ohms and an open loop voltage of 1,5 volts, then the current would not be able to surpasse 1,5/5 = 300 mA even if you had it hooked up to a perfect short circuit.
Further more, it is recommended that the consumer has a significantly higher resistance then the voltage source. This is because the consumer and internal resistance are in series and we want most of the voltage to fall of on the consumer (ideally little to no voltage falls of at the internal resistance)
Tldr: Maximum Current from a battery is limited due to internal resistance. The resistance of the load should always be significantly higher the the internal resistance of the voltage source so that most of the power gets used by the consumer.
You are forgetting internal resistance which is not zero!
just spotted the extensive list of links in the more. Wish more channels did this! So much easier to quickly see what is there rather than fighting the "youtube scroll troll"

This would have been really helpful whenever I first got in the sub ohm vaping
Can you please make a video where you explain current density and how you calculate it? I've been looking it up on UA-cam but nobody simplifies it enough for me to understand.
Also, if you see this comment, i want to thank you very much for every video you've made, you thought me a bunch and i appreciate all your hard work.
Do you mean electrons per second? ua-cam.com/video/kcL2_D33k3o/v-deo.html
@@EngineeringMindset I think he means Watts/battery mass. Or more simply Ah/mass for equal volt batteties.
@@EngineeringMindset electrons per wire thickness, calculating the area of the wire and how, for example the density changes when passing through both a 1.5mm wire and later down the circuit trough a tungsten wire i.e a light bulb.
@@artsmith103 that would also be a nice video
@@vlad516 What I described is called charge density. Lithium quite high, Pb is lower but there are Pb benefits.
What you're describing sounds like current Flux. Try that key word. I've never heard much concern about this. Wire gauge per current charts are easily available. Approx. 10amp=16ga, 15amp=14ga, 20amp=12ga, 25amp=10ga. Many more options and technically length of wire influences choice.
I was just talking to someone about how this works… thanks!
Love your videos. They just make this technical information really sink in. Well done!
Just as a FYI, I personally know AA batteries capacities are all over the place from different manufacturers etc etc.
And I know you mentioned this slightly at the start, but I don't think it was stressed enough when in the video the capacities of these batteries were changing from 1250/2500/3000 from scene to scene and then throwing additionally different ways to calculate the different topics.
It might have been best to reduce the amount of variables a new person to this topic had to think about and use a single capacity throughout the educational video.
Neither Tim Allen nor I ever considered this Q.
The answer was always, "more power."
Oh, I thought you were going to explain why... Like, why we don't just create a greater variety of individual cell voltages. Why 1.5v is a standard. Why, some batteries are made of individual cells inside the wrapper. Etc.
It's based on the chemicals used. Extremely simple batteries can be just two metals. I think copper and nickel have differing electron shells, where one of the metals wants to get rid of electrons and the other wants to gain them. Difference in voltage happens because of the electrons spreading to the other metal and becoming stable. So copper, for the sake of me not googling it and reexplaining, goes from being neutrally charged with equal electrons and protons to being negatively charged because the want for full electron shells outweighs the strength of the electrons repulsing new electrons.
The specific voltage levels come from the variety of metals and liquid compounds used. 1.5 might be standard just because it's made using the most common materials. The fact that batteries of differing sizes are just smaller batteries in series is because of cost of making 1000 of the same type being cheaper than 100 of this 200 of that
The cell voltage is dictated by the chemistry.
Hi Paul I love your videos and keep making videos your helping to make new Engineers
Can we use the discharged batteries of Blood pressure monitor and fit it to the quartz Wall-clock ?
oh that resistor thing is interesting... I had some like that where they'd measure high but fail to do anything under load.
Why would that happen?

Nice bedeo u use all my battery in series I much more like more the more bolts???!! ❤️ ❤️ ❤️
I’ve never heard them called crocodile clips instead of alligator clips.
I prefer to use deinosuchus clips
It's a British thing 👍
yeh from UK and never heard of an alligator clip
Crocodile's seem to be found around the world.
I've only ever heard of the American alligator.
And can only tell them apart at a glance by their bite.
Yea in america I hear alligator clips more.
Is it that it uas run out of charge or is it that the battery just cant produce enough current to power anything beyond its current value? By my thinking it should still be able to work at .8 v if the devicr is .5v and minimal current draw.
Presumably it would work. That said, the amount of current you could produce would be minimal due to the high internal resistance, and the battery would quickly drop below the minimum voltage. It would have such a short lifespan that it wouldn't make much sense to use. Also, if this was a secondary (rechargable) cell, draining the battery down to 0V would probably destroy the battery and prevent it from being recharged.
@@TheVonMatrices so its not the loss of charge it becomes unable to give what little charge it had left. I get it.
Can u do a video on train signal and interlocking logic and relays? Not sure if you are knowledgeable of the subject, but would really love to see that. Can't find anything on the topic anywhere. Thanks for all the incredible content.
This is an excellent channel.
In real life applications, I think we don't use parallel power source because the battery voltages are not exactly the same. When in an open l circuit, the batteries, especially rechargeable ones, would slowly lose charge by charging each other.
@@kennmossman8701 it should only be done temporarily.
Currents also add up in parallel connection
Technically we connect cells to make a battery. After that, batteries too can be connected obviously. But even though we call AA, AAA, B, C and D cells batteries (in the vernacula), they are not.
To give device longer battery time, and or, more voltage, either hooked in parallel or series.
can you make a video about the difference between current source and voltage source? And how to make a current source .thank you?
Thanks for you... Great channel sir
My pleasure
If you had a 9 volt battery, what kind of circuit could you build to have +5.00 Volts output?

Nice video
Connecting batteries together is to either increase voltage or amp hours(runtime) of the system, or both, depending on the configuration of the batteries. The end.
I was thinking this yesterday
Powering raspberry trough the headphone jack? This sounds like new challange for me
Because voltage is additive in series and amperage is additive in parallel.
Well in series there's more voltage in parallel same voltage but I increase amperage
Great video!!!
Does this also apply to inverter batteries? Say for example. If I have 8 batteries in series to make a 48v battery bank, vs 2 sets kf 4 in series connected in parallel for a 24v battery bank. Does it last longer than the 48v battery bank?
Same amount of energy, any way that you mix them. The system that uses the batteries will determine the configuration.
Yes the capacity will increase
In the case of an inverter, the inverter will determine the battery configuration. If you have a 24V inverter, trying to run it off of 48V will destroy the inverter. On the other hand, trying to run a 48V inverter from a 24V supply will not power the inverter no matter how many sets of 24V you connect in parallel.
You should always select your inverter to run off of your expected battery configuration.
HOWEVER, the topic regarding inverters that is most commonly referenced is Watts, or the amount of power a given inverter can produce. Watts is calculated by multiplying voltage by the current supplied, and will not change with a reconfiguration of batteries. Your example of 8 series (8S) for 48V versus 2 parallel by 4 Series (2P4S) would both produce the SAME Watt-hour capacity.
@@JasonSimpson1966 which means that both setups , the 24v system and the 48v system, would both run out of power around around same time assuming an equivalent load. That's what I'm really asking. If the same number of batteries set up at a lower voltage to increase the ampacity would last twice as long. But I'm guessing it would be the same. I was a bit confused by this vid when he said it doubles the duration of the batteries putting them in parallel. I just always thought it was the same for regular batteries and inverter batteries.
@@mikemosc3254 doubling the batteries doubles the duration ONLY if using batteries of the same capacity.
Additionally, where inverters are concerned, having a higher input voltage generally means a more efficient inverter, as you have less in losses because you don't have to step up the voltage quite as much.
Question, Why do we use the term battery for a single cell?
A battery is a group of cells connected inside a single package.
Like a 12 volt car battery. 6 cells connected in series to form a battery.
Or a cordless power tool. Multiple cells in one package to make a battery.
Even on the package it refers to them as cells. Are we that lazy minded to not correct others or just go along with the flow?
Now a 9 volt battery is a true battery. Comprised of 6 cells inside.
Because we like it.
why do i always log onto you tube and find that you just posted a video :>
Parallel cells actually have less capacity than series cells, because they are constantly discharging / charging each other. So connecting cells in parallel should only be done temporarily.
You can connect the batteries series/parallel as well
#Thank you#
Ok....lets use the correct terms. There are single cells and when combined with other cells make up batteries
Thank you for awesome videos. Wish my teachers were as clear. Have given some 10 to 12 yo kids links to your channel
Actually, if you discharge a cell at a lower rate, you will often get the full capacity, if not more! For high drain devices, that can drain the battery in an hour or less, you'll typically get ~1/2 the rated capacity. (a thing called Peukert's constant) Another thing, this 1.5 volt battery is actually called a cell. 2 or more cells connected in a series, forms a battery. I don't know, if multiple cells connected in parallel for extra capacity is called a "cell" or "battery.
If testing suitable batteries for creating a battery pack (e-bike), should you charge them fully before reading the Voltage of a multimeter?
Not sure of your question but here are some relevant topics for Pb 12V:
The charging voltage is the extra voltage used to push amps into the battery, around 14V.
Float voltage is the fully charged battery being kept at full charge by controller, around 13V.
Battery full charge is off the controller a short time, around 12.7V.
So when you are testing with multimeter you need to be aware of battery situation. Temperature affects all of those numbers.
Check our new Multimeter tutorial out ➡️ ua-cam.com/video/4lAyzRxsbDc/v-deo.html
When calculating how long a AA/A type battery lasts, assume 90% of capacity /mAh ,never lower than 85% from full/ less than 2yr old or so. Rule of thumb for u :)
consider two battries A &B.
battery A positive is connected to a one terminal of 2 terminal load.battery B negitive connected to another terminal of same load.
why circuit doesn't work if both batteries A and B not connected?
Battery A positive is ready to take electrons, Battery B negitive ready to loose electrons. but why circuit doesn't works if we don't connect both batteries.
Because the battery isn't ready to send or receive electrons, no chemical reaction is taking place, it is an open loop. ua-cam.com/video/PXNKkcB0pI4/v-deo.html
The first and most important thing is that they wouldn’t be batteries if we didn’t connect with together. It takes two or more cells to make up a battery. What we call a AAA “battery” is actually a AAA cell. If you put three of them together in a flashlight, then you have a three cell AAA battery.
I detect a highschool Science teacher
Maybe we just just use 9V batteries then.. since they are 6 AAA CELLS internally.
Why does a battery have to contain two or more cells, and not just one? I am trying to find sources proving your point, and every source says only one cell is required.
@@piguy4137 my understanding is that the word "battery" is an array of things: like battery-farmed chickens or a gun battery.
@@asbestosfibers1325 I tend to agree, but it is pedantry. Interestingly Google definition is "a container consisting of one or more cells, in which chemical energy is converted into electricity and used as a source of power."
why does a dead battery without a resister sometimes show 1.5v?
2:50 how to find circuit current? (Measuring)
Please see our video on electrical current, or simple led circuits
I am waiting for your new videos .
why batt testers insert . / apply ac 1khz signal into batt to test it
What I've always been wondering is how come the next battery in series doesn't blow up due to the accumulated voltage?
The concept of over charging a battery with a higher voltage is the lines of what I'm thinking.
I was wondering why the batteries in parallel don’t short circuit.
@@PlayitonPan They don't short circuit as the voltage on the neighbour is opposing it, but they do equilibrate and they will usually end up with exactly the same voltage.
Hey I'm waiting for the video about Synchronous Motor
Don't worry, It's on the list, these videos take a while to make.
@@EngineeringMindset Yes I no that it is hard to make this type of videos
Can you do a video on Steam-turbine-driven chillers, please?!
Still confused. Why is the battery that shows 1.0 V considered completely out of charge?
It can't sustain the chemical reaction to push electrons through the circuit. It has enough potential differece only to show a voltage difference.
For many cases when you have two 1.5 batteries and one have 1.3 -1.4 V your device would not work properly or work at all. 1 v mean it's dead for a long long time
1.5 V battery is typically full at 1.6V, 90%full at 1.5V, 75% full at 1.4V, 50% full at 1.4V, 25% full at 1.2V, 15% full at 1.1V and empty at 0.9V
Batteries with 1.3-1.4V should have a lot of energy (might be unusable) still there.
Either you'r devices draw a lot of power or cut out too early.
No series parallel connection?
Hmmm...shouldn't battery testers have a built-in resister load to properly test batteries then?
Yes testers have internal resistor.

Picture in thumbnail is wrong. In series the bulb would glow brighter than in parallel.
The thumbnail shows the series lamp is brighter?
@@EngineeringMindset The light of the bulb, with the batteries in parallel (left) is white (=brighter), and the light of the bulb, with the batteries in series (right) is yellow (= less bright).
So if 2 alkaline batteries in series are added, then why do you get less than 1.5 volts, if one of the batteries is dead, and the other is brand new? The dead battery acts like a resistor. That is not captured in the equation. Because, try it, 3+0 = 2.something
Check out NEW resistor video, everything covered! ➡️ ua-cam.com/video/DYcLFHgVCn0/v-deo.html
If the battery has voltage it still has charge though right ?
So technically its not dead till it has 0V ?
just run whole lot of dead batteries in series to get a higher charge !
No! The internal resistance rises as a battery loses its charge (due to the chemicals being used up, mainly the zinc case) so on open circuit (i.e. no load connected) a dead battery might show the full nominal voltage with a high-impedance voltmeter.
(connecting batteries) So they don't feel left out.
I dont understand why a battery could show 1.5 V under no load but still not being able to drive over a small rezistor, as shown.
The internal resistance has increased. If you draw almost nil current, the voltage is 1.5, but once a current is drawn through an external resistance, you have to include the internal resistance too.
😊😊
I wonder what setup would be better if you want a 2x2 battery configuration: two parallel sets in series, or two serial sets in parallel?
What about "squeezing" the battery when it's low, is it real? To be honest 😸 I do it every time
I put mine on the radiator or rub it with my hand to warm it up, always works but probably isn't the safest idea
@@EngineeringMindset Yes, warming the battery improves the chemical reactions with the last available chemicals as well as lowering the internal resistance somewhat. The opposite is also true - to conserve a battery, it is best to keep it cool.
Two cells of 1200mAh charges connected in series don't add up? Bizarre. Then where go the extra 1200mAh of charges?
They will have twice the voltage and so they can supply twice the current through the same resistor, but the total capacity remains the same.
Check out NEW resistor video, everything covered! ➡️ ua-cam.com/video/DYcLFHgVCn0/v-deo.html
Another suggestion: to combine/step-up energy MAGNETICALLY, to gain/enhance fault-tolerance as a dead battery wouldn't stop other power cells from cooperating together while staying electrically isolated/independent...
Seen our new Transformer video? here ua-cam.com/video/jcY4QN7awEc/v-deo.html
Trick question: if we parallel series battery, will it give more current and voltage?
Yes it will.
Boats/RVs often use multiple 6V series pairs in parallel to build a pretty big 12V battery bank.

So a battery is functionally useless, even though it has more than half it's charge left. I will have to remember this whenever someone mentions that batteries are more efficient than fossil fuels.
It was about 30% here as well.
Not only did I learn about batteries today, I also learn that outside of the US, that alligator clips are called crocodile clips. Makes sense since alligators only really exist in the Americans and China. I wonder if the crocodile clips are more pointy than alligator clips?
I was really hoping that you would have explained why battery cells are 1.5 volts. I am sure that I must of learned why but I don't remember. Even big wet systems that I used to work around (I am not an electrician) were 1.5v cells for 120v battery bank.
The voltage depends on the chemicals used to make the battery. Alkaline batteries contain zinc and manganese dioxide soaked in alkali, which results in 1.5 volts. Lithium polymer batteries are usually 3.7 volts since they use lithium metal and either cobalt oxide or iron phosphate. Lithium is more energetic than zinc so the voltage is higher.
@@suey1690 thanks
These are NOT batteries, they are cells. They only become a battery when more than one are connected together. The derivation of the word 'battery' is Battery Of Cells.
You beat me to it.
Technically you are correct, but you would lose everybody if you say “put that cell in the remote control.”
Clarify this : mAh doesn't really say much about the capacity. It's the wH (watt-hour). Regardless you connect the battery in series or parallel, the capacity adds up.
By connecting in series, you effectively increase the voltage w current capacity being the same (Ex 2x 1.5v 1aH battery in series gives the total capacity as (3v at 1aH) 3wH, and in parallel (1.5v at 2aH) as the same 3 wH.
This is a very common misconception I feel. It's wrongful to not include the voltage in your capacity measurements.
I thought the same. Like capacity is basically charge in Coulumbs, they can not dissapear right?
Individual = cell
Collective = battery
Trivial yes I know.
Yes it is. Most people think "cells" are in prisons or perhaps something to do with cellular phone networks.
But connecting batteries in parallel also increases the capacity to store energy.
So connecting the batteries in series will increase the voltage but the capacity will be the same, whereas in parallel will increase the capacity but the voltage will be the same, for example, when you have 3 batteries and each of them has for example let's say 12V and 3000mAh, when you group them in series, the output voltage will be 36 volts but the capacity will be the same, whereas in parallel the voltage will still be 12V but the capacity will be 9000mAh.
So if you want more capacity without increasing the voltage you wanna connect the batteries in parallel, and if you want more voltage you have to connect the batteries in series but the capacity will be the same.
Like a UPS and power station.
The ups mostly a Series the battery's first, but the power station mostly a parallel
Love the videos man!
Glad you like them!
correct me if I'm wrong if a battery rating is example 1.5V that doesn't means when you measure them using Voltmeter it doesn't display 1.5V but rather display around 1.8V indicates that it's full charged. that 1.5V is the standard voltage for that kind of battery.
