Lol that's the Great Scot music played over NCS

Great tutorial. I didn’t know the role of the processor in charging. For prolonged battery life, Chargie USB stick is the real game changer.

Very Helpful, Thank you

great video... I got a quick clue about batteries having more than 2 terminals...Thanks bro.

thanks for the share it's exactly what i needed to know quickly.

Always happy to see an English title and surprise Indian guy actually speaking English. Thank you for making it 2 languages, this way the whole world benefits.

Thank you. I did not want to buy a new battery and decided to go with an external power source for a "sim card wifi hotspot". I measured the thermistor of a cold battery (8k Ohm). With the external power source i used a 7,5k Ohm resistor and it works like a regular battery 😉

3 terminals can mean battery status indicator [BSI] or The the third terminal is a battery temperature indicator . but if it's got four terminals then it's a [Bsi ]Battery indicator and the a Battery temperature

I want to replace my modem battery which standard old phone battery (square glat type) with 11650 type battery which has more capacity. Is it ok if i just connect + & - only? Is it still working if im not using BSI and BTemp? Thanks.

Awesome video, just what I was looking for. Is there a way to tell which terminal is the BTEMP and which is the BSI?

I have a pet project where i will need to charge a 12volts 10amp bike battery. I have a used mobile radio charger that i intend to use. The charger has 4 terminals: obviously +ve and -ve, then BSI and Btemp(much thanks for your video). I dont have a problem making the +ve and -ve connections to the battery for charging, however question is what should i do with BSI and Btemp terminals? Do you think i can connect them too to get the information they can give and how do i make such connections?

I thought it would be to do with balance charging! Very interesting though! I suppose phone batteries are typically one cell.

❤Thank you, no battery no phone usage.

that was very helpful , thank you sir , I subscribed to your channel , keep up the good work

Super simple explanation thanks much!

Thank you. I never asked this.question until today

Thank you sooo much.. quick and easy answers. 🤗

Probably greatest video for this theme, thank you for info 👍😄

Awesome presentation. Great video. I studied back in the 80s. Love electronics.

Thank you for your informative video. I have a question. If the original battery has 4 terminals and the replacement battery has 3 terminals, is there any problem using the 3 terminals battery?

I have a pair of true wireless earbuds and I lost it's charger. The earbuds have four terminals places like 🔢. Will they charge if I find the + terminal and the - terminal (2 terminals) out of 4 terminals and charge those two? Or do I also have to connect other two (BSI and BTEMP)?

Well said....Thank you...

Thanks this video was really helpful as i am making a charger for a small camcorder battery which also has three terminals and i didn't know if the third terminal was to do with charging or not.

I want to put a laptop battery with 2 black and 2 red wires in a homemade boombox. Use the power adapter to charge it. Am I right to assume that the adapter doesn't have all the chips to know how much to charge? Meaning the chips which communicate with the battery might be on the motherboard of the laptop?

I've been wondering for a long time.

great and simple thanks .

This information was very helpful to me. Thank you.

Realy informative vid thk u

I enjoyed your video. It was very helpful. Thank you!

thank you for this imformation bro

*So is it safe to use phone battery + and - pins as a replacement battery for simpler li-ion powered devices?*

Please Do a video of non removable phone battery terminals

2:52 How about Samsung S5 battery? Is It same kind? Becose it has 4 pins but 1 has a plusmark and 3 a minusmark?

Thanks brother Thankyou very much your video and AUDIO QUALITY SUPER

Simple and clear explanation. Subscribed your channel. 👍👍

is it possible to bypass the battery and connect directly a psu or similar to the motherboard for testing it, in case of diagnostics on the mobo?

thanks for informed

Hello :) at first thanks for the video. I’m now working on my phone Wiko Tommy , to make a car info display while driving. That phone’s battery has three terminals. I hooked up positive and negative wires along with the Correct position but it does not work. By accidentally I hooked two ( positive with Btemp terminal) up ,surprising and unexpectedly it was on. So can I use like that one ? Positive cable to positive terminal and btemp, then negative cable to only negative terminal. Thank you :)

thank you friend all the best

Excellent video. thanks for the nice information.

Thanks bro, this video is very informative and knowledgeable

good explanation easy simple

Enlightening. Good Job.

please note that some batteries have NFC circuit and they use one terminal for that

Thank you, Now I don't have to wonder anymore

exellent i realy enjoyed your information

Very informative, nice now I know, thank you.

Thnx a million for info

…Very helpful!

Very informative

nIce drawings too. Well done

Thank you for not saying "Ok, Guys" in every sentence as I've heard in other videos. Your content is very good but repetitivly hearing that phrase makes me have bad dreams at night!

Mobile- Gudevening. Can l start my moto w180 basic phone without battery? Some videos guide to connect data cable. Instead of data-cable can l use charger? (It has 4 terminals inside, so the confusion is where do the wires stick, 1st & 4th? Or some other combination) Pl reply.

*Thank you so much sir*

Thanks a lot!

thank you broo

Good info keep it up

This is great video you are great sir,

thank you

Thank you

Anyway to trick the bsi or btemp to think its conected even if you dont have original battery?

nice information...

good wok and thank you for the info. 🔥

Thanks alot.

Can i use Redmi Note 4 batteries on Redmi Note 5? it has the same socket a.k.a it fits perfectly. I wonder if it has the same pin positions? Thank You

i have battery xiaomi BM42 and i want build powerbank with that.. can you give me explanation about connecting the battery to pcb powerbank? because the battery have 4 terminal..

Sirji superb

Some of the Lithium Ion cell phone batteries have a large white rectangle next to the terminals. What is the function of that rectangle? Example at or near 0:15

Great 👍

Guesstimating now, but I'd be very surprised if the BSI isn't for battery balancing - to make sure that each of the two Li-ion cells involved are charged equally - which does indeed ensure proper charging and longer battery life. However, if that's the case it would not only have to be a sensor, it would be a connection so as to be able to charge the other cell separately if it wasn't in balance. If one looks at say a Cordless Screwdriver battery which has several cells then one finds a connector for each cell to connect to the charger - the higher the battery voltage = the more cells = the more connectors.

Bro please tell me can We use moto g71 Mobile battery in ke novo k8 plus Mobile ?

Very useful video bro........

You did well

Anyone know if there is 5 terminals whats the positve and negative terminals. or is there 2 complete circuits and one status terminal in the middle? Its a battery for a total station with a laser. 56wh lasts c 4hours. charges on 18v charger.

Thanks

thanks

Can I charge mobile battery by giving 5volts directly to the + & - pins from SMPS of my PC.

Good video, thank you. But the terminals with samsung battery are arranged differently, they are from left edge to going to the right for instance, positive, blank, negative and then blank, why?

If so, and I'm not saying it isn't: why is there no circuit to stop charging until the battery gets to a certain amount of discharge and start charging again?

great scott sound :), good video though!

is there a way to recharge this battery nowdays with 2 pin recharge?

Great video!! With Quick and Simple explanations that any laymen could get as its not muddied up with a bunch of tech speak!!! While yes, your accent is heavy. I had Zero issues understanding you, thanks to years of dealing with customer service reps lol jk.

What is T & D points working almost in handycam batteries... Please make a video

Tnx guy

Nice

So, why do I only get a few milivolts when I test (multimeter) a 100% charged 4 pin battery on the 1 and 4 pins. Or on any pins for that matter.

Watching this video I subscribed to your channel Everything told really logically specially that thermister use and that interrupt signal send when we remove battery by bsi awesome dude awesome

Battory Baki ke 2 terminals kese pata kare ke bsi he ya btemp he ?? Or mobile pcb pe bhi kese pata kare ki vo terminals konse he ???

great scott intro music i see

nice video bro

Brother i have a tablet which runs on 3000 mah battery which got damaged now i have two different cell phone batteries one is 1750 mah and other is 1800 mah so can i salder there positive and negative terminals to the tablet is it safe and would it work

Which terminals are for charging the battery, and what for the other two??? Please explain

Good

Can I use another battery say a Samsung batteri which my phone require 3 terminals only but the battery I look for has 4 terminals? I guess it could be fine since the connector would only connect 3 out of 4. While the fourth terminal would just hit "wall". Should be fine right? Like a outlet who has plus and minus and perhaps 3rd that is GROUND and IF there was a 4th that would just be whatever like data to do say temperature sense, remote control etc. Thanks btw for the info. Didn't know what the ports what called, now I know: terminal!
