I think they might have made one of those already.

[@FrancoFireWall]

Nvm, it’s in Leisics channel

[@mas-udal-hassan9277]

Nope

[@solapowsj25]

Excellent tutorial. By keeping the battery well charged and never leaving it in a completely discharged state, my TATA Nano car 🚘battery gave 9 years of trouble-free service.

Explained well but the Cathode and Anode terminals are wrongly assigned 🤦🏻‍♂️

[@temiloluwashonubi3690]

Really helpful

[@abdlmoty]

Thank you so much ❤❤

[@wherami]

Great one

[@oldtownscouts3712]

Aren't the anode and cathode swapped in your illustration? I've always seen the cathode called out as the negative terminal

[@reececrook7021]

different diciplinces call different charged sides the anode and cathode, in physics for electron guns and stullf its flipped as compared to and chemistry for things like electrolysis, however idk if the video has it right for batteries, i just know it isn't consistant

[@DEEPAKKUMAR-ns4rv]

I seen many video about battery , everywhere positive electrode called as cathode I don't know why

[@anshsrivastava61]

bro this is next level

[@ecez2599]

Can you do one video for zig zac transformer, thanks.

[@BenasKulpis]

Hello, I found that acid from PB battery is getting chemical reaction with white cliffs ground - the white ground. I am bad in chemistry but the elements is making some gas. It can use with pressure barrels to make pressure for turn some turbines - such wind or something similar. I used rain water for the battery, says it fine. Just dunno how long the reaction last, maybe it is just salt or soda. Thanks

[@agentfiveseven7270]

Correct. As lead acid batteries charge they produce hydrogen gas, though it isnt much

[@EngineeringMindset]

[@KokLiangLim]

Why the electrons won't flow to cathode via electrolyte, what prevents it from moving that way?

[@Frizzy9000]

If you look around 2:14 it gives a general idea. The electrons were only released because of the sulfate reaction with the lead. The cathode has oxygen bonds whose charge only reacts towards the hydrogen so you could say it is more "stable " and does not want to except any electrons. Since the oxygen only got released from the sulfate reaction it makes a sort or "shield", combine that with the fact that hydrogen is combining "towards" the cathode and you get a one way trip. But to be clear even that is oversimplified as you make a point. I am not an expert but at higher voltages/shortcircuits this can happen. There is also thermal and electrical shielding to prevent that, hopefully someone can give more details/correct on finer points

[@user-dy1vf7lu3i]

QUESTION: Cathode is positive and Anode is negative? Why does google disagree? I’m confused af

[@Ottos_ScLm_Race_videos_2009_on]

He is correct, I just looked at Google where are you looking on Google? I found the same on Google that he has.

[@ravenous9577]

So this can be complicated. You are right to be confused.There is what is known as conventional current which is the flow of "holes" (or the absence of an electron) towards a negative charge and then there is electron current which is the flow of electrons towards positive regions. The term anode and cathode depends on what type of current you are defining. If conventional current, then the anode is positive and cathode is negative. (Holes -> Negative Region) If electron current, then the anode is negative and cathode is positive. (Electron -> Positive Region) In essence, an anode is the "Source" and cathode is the "Drain" in either scenario. Regardless if you are using conventional current or electron current, the flow of charge is going from anode to cathode. In chemistry, electron current is usually the preferred perspective. So negative anodes, positive cathodes. That is why anions are negatively charged and cations are positively charged. In electronics or electrical engineering, conventional current is typically used. So positive anodes, negative cathodes. In battery technology, both electrical engineering and chemical engineering can be used which is often a point of confusion. Why do people use conventional current? Just became a stupid convention imo. I much prefer electron current as electrons are actual particles whereas holes are just conceptual placeholders. BUt in terms of the flow of charge, I suppose it doesn't make a difference in most scenarios.

[@rishavjain5087]

Becz Cathode can either be +ive or -ive so does the Anode. Actually Cathode is the one where Reduction (Gain of e-, *confusing names indeed*) occurs and at anode Oxidation (loss of e-) occurs you can remember this by RED CAT 🐈 and AN OX 🐂 mnemonic btw cathode is +ive in cells which *create* electric current and -ive in cells which *require* electric current

[@nonyabusiness9747]

QUESTION:: LED BATTERY SHELF LIFE? How long Are brand new batteries climit control stored.. good for? I mean after a battery tainer charge are they still fine? Maybe top off the acid?

[@nonyabusiness9747]

It was said at the end of this video, "if we leave the battery.." does this mean a brand new battery left for years without charging would fully dissipate its energy? Asking because I've just been given a unused battery bank, the catch is they've been sitting for some years.. are they worth messing with? Trying to low budget power our offgrid home here..

[@KJMcLaws]

@@nonyabusiness9747 there is internal resistance always. So yes they will self discharge if not maintained with a charger. If you have a bank you might try charging all of the batteries and test them to see if and how well they hold the charge. There are also desulfurization chargers that can try and restore some of the life in the batteries.

[@nonyabusiness9747]

@@KJMcLaws thank you kindly

[@EngineeringMindset]

Seen the new LED explained video? so much detail covered! kzbin.info/www/bejne/hWmwY61ona6Vl8k

[@Drfrodoskywalker]

Now that this is explained, do an AGM

[@ASKstrive]

I wish i could be more easily explained: What is plate ? Properties of plates ? Deep cycle ? Lead acid battery for home advantage & disadvantage ? Why a 23 plate battery become useless in 2 years ?

[@hybrid.roodragon1226]

can you do a quick video on how a lead acid battery dangerously overcharges and causes a sulfer smell

[@LiborTinka]

I think this is due to reaction of lead in hot conc. sulfuric acid which is exactly the overcharge conditions: Pb + 3 H2SO4 ----> Pb(HSO4)2 + SO2 + H2O So the sulfur smell might come from the sulfur dioxide gas being expelled. This requires temperatures of 30-50 oC and ~80% H2SO4 (I think batteries don't go much over 60% but I don't know much about practicalities of the lead-acid battery).

[@davidfalconer8913]

ALWAYS recharge your Lead - Acid battery as SOON as possible , after ANY discharging ! ...... leave your ( almost ) flat battery ( in an old shed / garage , for weeks ? ) , and it will be dead forever ! , and with a 12 Volt car battery make SURE the charging voltage NEVER exceeds 14 Volts , or you lose water ( especially important for sealed or gel types ............ DAVE™ ............

[@solapowsj25]

👍

[@ibnewton8951]

01:30 You have labeled the cathode as being positive and the anode as being negative. Isn’t this contrary to conventional current flow?

[@igorordecha]

From what I heard, anode being positive and cathode negative is used when talking about the receivers of power(LEDs or betteries that are charging). If the device is outputting power(like a battery that's being discharged) it's reversed. Cathode is on the + and anode on the - terminal. I don't really know why but I believe its about the direction of the electrons going through the terminal. So cathode would always get electrons and anode would always give electrons.

[@Ottos_ScLm_Race_videos_2009_on]

One thing he needs to explain is a generator VS and alternator. And you can't directly charge a lead acid battery with and alternator.

[@FireCrowsWorkshop]

Say that to any decent mechanic and they’ll call you a 🔔 🔚. 🤷‍♂️ Quite simply because every car manufactured in last at least 40 years has been fitted with an alternator. And all those alternators have rectifiers and voltage regulators simply because generators aren’t efficient enough.

이런건 인도가 잘하던데 그들은 자력으로 만들고 고치고 쓰는 영상도 있습니다

[@avashchipalu4565]

Lead oxide or dioxide?

[@theshemullet]

I like your videos but would prefer if you used conventional rather than electron flow. It gets confusing because although you're correct everyone else uses conventional.

[@anshadedavana]

In a circuit level (functioning of a circuit) , conventional current is okay but to explain and understand the inner working of components, current flow aka electron flow is necessary.
