Why do we connect batteries?
video description
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.

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.

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.

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.

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.

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.

The first and most important thing is that they wouldnt be batteries if we didnt 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.

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.

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

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.

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.

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.

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.

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.

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.

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.

A battery of 2400 mah with 1. 5 v provides the same power compared to a battery of 1200 mah with 3v
So can anyone explain since it provides the same power why does it matter we connect them in series or parallel?

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!

That's an easy answer money materials and Profits. why sell them one thing that could last twice as long as two things? when we can sell them two things that last half as long as each other for double the price.

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.

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.

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!

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.

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.

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

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: )
