4:55 Don't be silly Luke, we all know what would happen if Apple got it's hands on a new battery technology... (WOW, look how much room we can save with our higher density batteries, we can finally make our phones an entire 3mm thinner than the last iPhone, too bad it'll have nearly the same battery life as before.)
vgamesx1, and do not forget that such a batery from the chewed apple would still be not enough to let the phone user to list through all the patents that the company would kower the technology with
+Ivaylo Kostadinov The first one will. But the "S" variant will use a revolutionary new material called the 7000 series aluminium that prevents it from bending. Everyone will then praise Apple for their innovation and for fixing the previous problem. /s EDIT: Added /s because people couldn't tell this was sarcasm.
+barnstormer322 Not a question of ergonomics but cost. If something is made smaller, it takes less money to make. That's why the new Pascal generation of GPUs is half as much money (on average) and same or better performance than the Titan X. Also, who wouldn't want a phone 3 mm thick. The thing holding us back from that are mostly batteries and 3 mm thick phones would sell like hotcakes.
Hendlton Thinner means less comfortable to hold. I understand Apple's motives - a thinner phone is more aesthetically attractive - but that's about the only advantage other than cost for what is at the end of a day a less consumer-friendly device than a slightly thicker one due to the thinness and therefore lack of comfort. Also the GPUs are the same size, hence the almost identical cooling shroud. If you're referring to the die shrink, it's actually just as expensive in terms of materials because of an increased transistor count, not to mention the huge R&D cost associated with such a huge change.
Hendlton not exactly. Smaller means higher precision means higher defective parts count means more material and energy loss means more manufacturing processes and development as every tenth of a millimeter shaved of a screen means developing stronger glass, better matrix etc, from case means stronger alloys or else #bendgate will happen again, that also means components will have to be more fragile and packed tightly on the PCB... And getting rid of 3,5 mm jack or having big ugly cases doesn't help...
+MyriadesusTV its not about density, but about generating and storage costs. petrol is ready to use right from the groud to the device you want to power. electrical energy is both harder to generate and more expensive to store. wind turbines, solar energy and atomic reactors sometimes have lower return ratio, batteries are more expensive than just fuel tanks and a lot of electricity is generated by burning petrol
William Meisburger-Iwata we just can't extract most of it's energy in a useful way. mercedes new f1 car has about 51-52% of thermal efficiency, a common roadcar is somewhere between 25-35%. electric vehicles on the other hand can turn between 70 and 90% of the energy charged into useful work, but the energystoragecapacity is way lower tha in Internal Combustion Engine vehicles.
I am always confused when people complain about needing to plug their phone in every night. Like I get that we want to be lazy, but how inconvenient can it really be? You're likely going to be sleeping in a place that will provide such a outlet to plug your phone's charger into. I mean, I understand "progress" and all that, but honestly the people that think batteries are not good when they only last for 26 hours are fucking idiots. They are good, and anything past 24 hours worth of battery life is a luxury akin to a champagne really. It literally sounds like millionaires bitching that they only got to drink one bottle of Armand every night, and that's why I really wish batteries stagnate so people just shut the fuck up about battery life. People are idiots, thinking charging their phone every night when they go to bed is too much work.
If one just had to plug his smartphone when he goes to sleep it wouldn't be a problem, but look at the iphones: they die at 2 pm, and that's pretty annoying. And when you have you screen at max brightness in summer, with maybe Bluetooth and 4g active, there isn't any telephone that has enough juice to power that from 7 a.m. to 9 p.m. That would be the goal, in my opinion
Thats why one should buy a phone based on what one need. Its simple: Need long battery life => Do not buy a phone with short battery life => Profit. My OnePlus2 lasts me for a day with full brightness, gps, wlan and bluetooth usage, up to 3-4 days when saving on energy. And as Sherrif said.. just plug the thing in overnight and stop crying.
you don't get it. Every night is just at mild use. The thing that really drives me INSANE is my phone suddenly draining to 10% by barely using it and then dying BEFORE i get home. It's not about being lazy and not plugging it in, it's about having the headroom and buffer should anything happen. It has happened that was going to meet up with someone and suddenly after half a day my phone died and couldnt do anything at all
+kakureru They actually can be, you'd have to charge a premium to off-set the lifespan, which would make them less desirable. Look at NIMH's. They're $10-$12 for a 4-pack, nearly the same price of a 24-pack of alkalines, and good ones are _supposed_ to last 3-4 years before hitting half capacity.
+ZombieBarioth If you fully discharge every time. NiMH had the memory issue. If you repeatedly charged at half discharge, then they will develop a lower voltage and a lower capacity. That gave them a poor reputation, and why they are so cheap. Protip tho, if you do a few full discharge cycles, you can recover some of the capacity, but not all of it. Lithium Ion batteries are better in this department.
+kakureru They absolutely are. I work in battery research, and batteries are probably one of the biggest areas of research right now in engineering circles. Lots of people who aren't selling batteries (phone, electric car, and laptop manufacturers for example) want longer lasting batteries to have an edge over their competitors. They also want longer lasting batteries that are smaller and thinner and safer.
Richard Smith Well that's certainly good to know, I didn't know you could do that. I was referring to the advertised lifespan though, which is about how long the manufacturer would expect until people need to buy more.
3:34 this is not entirely correct. a high discharge(5-10%) and constant 100% charge will damage the lithium accumulator in the long run. my 4 years old netbook has only lost about 20-25% maximum charge level while most people i know who have notebooks have lost about 50% in 2 years. why? because of wrong charge behaviour.
+dafff08 my netbook will automatically enter the hibernate mode when it hit 15% charge level. i also set in the bios 90% maximum charge level. when im at home i remove the lithium accumulator and use a power cord. setting all options to power save will also help to reduce the wear because less loading cycles. if you dont need the accumulator store it somewhere where its cool with about 70% charge
So mah question is (powerbank) the lipo charges ur phone faster than the li ion and the li ion dies faster than the lipo right? If its right it i will buy for 60$ a lipo powerbank with 12000 mah with Qualcomm quick charge 3.0 with a usb c connecter + normal usb from cellularline (is that company good?)
+jd6133 not quite. Preston Garvey mentions they're pre-war tech, meaning he's more like 61 Years and 5 months off... And likely less, considering how widely distributed they are in the commonwealth.
+jd6133 - Well... true, but you said we're about 2 centuries off as if we WERE in the Fallout Universe. Besides, where were we, technologically speaking, 61 years ago, in 1955, compared to where we are now?
thinness performance battery life pick 2 we already can make phones that you only need to charge once a week you just need to get rid of the thinness craze that we are currently in (thicker phones will also be more durable) the ulefone power 5 has a 13,000mah battery and can last almost a week on 1 charge, it is thick and heavy (similar weight/thickness to an iphone in a battery case, but more energy efficient) but it is very durable, and the battery will not only last longer between charges, but it will also last longer since you are using 1 cycle per week instead of 4 cycles per day longer runtimes are possible with current technology, just make the device thicker and include a physically larger battery imagine the battery life of a galaxy S10 if it was double the thickness, but included a 10,000mah battery (maybe then i could get a whole day out of my S10 5G instead of being tethered to a battery bank if i go out for more than a few hours)
Actually there are several battery types that are ready but the prosess is slown down by goverments etc. There is even a battery you can cut with a scissor etc while in use with no chance of shorting and exploding
+Sci-Twi supercapacitors also can be used to start cars. You could make it a hybrid with a few Li-ion cells. You should not jump to conclusions and say supercapacitors suck in every way. They have their uses.
+Sci-Twi supercapacitors can last for a few million charge cycles without losing their energy storage capabilities as compared to lithium batteries. They can be used for noisy SMPS supplies etc.
Nice video, and I have used some of your tech quickie videos in my science class in the past and this one will be added to when I talk about batteries. Could you potentially do a video on how the computer power supply works, or the voltage regulators works. Not going to lie it would be great for when I have to cover Ohm's law.
I've charged Alkalines before, it usually works but it only gives you like a quarter to half of the battery time that you'd normally get, but if your in a pinch and can't afford 1-6 dollars for batteries well charging batteries seems to work... just watch them carefully.
I used to play with RC electricial models and I was always sceptical about that "no memory" thing. I used whole bunch of different types of batteries, from NiCd to Li-pol. I always used hi-end, competitive chargers that allowed me to see, exactly how many amp-hours actualy "got into" my battery (it also allows for charge-discharge cycling to regenerate batteries, setting your own charging current and much more fun stuff that taught me alot about batteries and electronics in general). Let me tell you: the better you treat you batteries, the better they gonna last and perform. And it's true for all types batteries, NiMH, Li-ion, you name it. ALWAYS try to discharge and charge them fully. Also, the lower the charging current, the longer the charging (obviously), but also the charging is better and moe efficient with the lower current (more Ah go in) and it's much better for the longevity of the battery. It is reccomended, for the long service of battery, to charge it with the current of 0,1C (e.g 2Ah battery - 0,2A charging current, which gives 10h of charging). Ocasionally, if you hurry you can increase it to 1C (1h charging), but not too often. It's not reccomended to exceed 1C, ever. It's weird to me that these days companies focus so much on performance of the phones, stuff like quick charging, but not the batteries themself. Plus you cannot exchange them easily these days and chargers are crap as always, which creates nothing but problems. And it's not even that difficult to make 5000mAh batteries that are small and fit in the phone (RC people used them for years).
In my younger ignorance I used to put alkaline batteries in a battery recharger and it actually brought them back to life for a couple more days. Maybe it just mixed up what was left who knows but it worked mildly with the more expensive brands and not so much with the cheaper ones.
it is not technically created. Is what he really means is he is transforming chemical potential energy into Electrical, thus "creating" electrical energy and the actual electrical energy did not exist before the reaction happened.
sorry but that was too fast. simply listing the most common battery types is lazy at best. you have to say why you'd use each one too, self discharge, power density, current density etc.
+Thanh Tran That's an in depth analysis of the characteristics of each battery type. This video was just about the different types...says right in the title. You also answered your own criticism. "It's too short." It is quick. That's the name of the channel. "Tech Quickie", not "Full in Depth Tech Breakdown and Analysis." It is a quick explanation of different battery types as fast as possible.....so I don't understand your criticism.
+Jween Tech I understand the title but sometimes quick is just too quick. People would want to know why one would use different types of batteries and not just list them by chronological order...
If anyone is wondering why alkalines say 1.5v and NiMh rechargeables say 1.2v.... The very short answer is that alkalines drop to 1.2v when under load and NiMh stay at 1.2v under load or not. The reason why NiMh lasts longer in some devices is that Nimh hold that 1.2v almost uniformly until out of "juice." Alkalines droop to that 1.2v then continue to gradually droop below to 1.15v....1.1v......on so on until it's dead.
1:14 THANK YOU for showing the RIGHT flow. It's driven me NUTS since a was a (..nerdy..) kid when a graphic would shown the flow from the POS to the NEG (So called "conventional" flow). I saw this crap in a grade school sceince book. I point out that it was outdated (and wrong.). and was told I was wrong. 🤬 This was 50 years ago...Still bitter, LOL.🤷♂️
It's mid-2021 and still no new battery technology. Still the same shit every single new device comes out. Why can't tech companies focus on improving their battery tech first rather than making their phones look like the slim versions of their ancestors back in the ' 70's 🙄🤦🏻♂️ New battery technology is out there and just reading about them they really sound impressive and promising. Why can't the big companies invest on those batteries and try it on one of their devices first. Not only they'll earn money but they'll also be able to help the planet that's dying because of us. I'm specifically talking about Samsung and especially you, Apple. Because the other tech companies are looking up to you both. Be a good example by showing true innovation that makes a REAL CHANGE. And that's improving your battery technology. Innovation not duplication.
i wanna ask... Does playing high-end games such as GTA 5,CS:GO,Medal of honor: warfighter,etc on my laptop while charging effect my system and battery-life? Also its a Non-removable battery im using the Asus A556UR
Ni-Cd are far from obsolete Ni-Cd provide right in spot balance of high current (Ni-MH is much worse), low self-discharge (Ni-MH is almost twice better), low maintenence (less then lead-acid and even Ni-MH), easy charging (Ni-MH is hardest one ever) and high volumetric capacity (lower then any lithium, Ni-MH but much higher then lead acid) there is no lift which sits in this spot I do not think batteries and especially rechargeable batteries are subject for tech quickie you may write PHD on rechargeable batteries every year for your entire life span and your grand children can pick it up and continue for another lifetime and it won't exhaust subject
OK but why does R/C industry use only Li-Poly while Li-Ion (18650's) are ubiquitous, much cheaper, have about the same charge density and there is usually plenty of room for them ..never had good luck with NIMH on any charger compared to NiCd..
Umm... Luke, the cathode is the negativity charged side and the anode is the positively charged side. Also Li-PO batteries have a lower energy density than a Li-ION battery. Li-ION are also MORE expensive than LiPOs.
If I connect a 9v battery with half charge to a 2.4v LED it will light but if I connect a fully charged 9v battery to the same LED it burns the LED out. This would indicate the battery only begins as 9v and slowly loses voltage. So a half charged 9v battery should be a 4.5v. Is this correct? If I connect a full charged 9v battery to 5 2.4v LEDs will it deliver all 9 volts to each LED or will it divide the voltage delivering 1.6 volts to each?
I am using . Will the laptop bypass battery & consume power directly from power source once its chargered 100% ? Provided I am using laptop with adaptor plugged in.Will it effect my battery life ?
You cannot "recharge" Alkaline, but YOU CAN REGENERATE Alkaline ! Each time, the capacity/voltage decrease by a lot, so it's very limited (there is other things to know when you do it too, google it !), but still possible. Remote controllers are happy with this.
Luke you did not talk about watt-hour per kilogram. Which is very important when you are talking about batteries for things such as: Drones, Cars and boats. Or even Wh/L for when ever space is of concern. The latter isn't as important. I the end because of this lack, this AFAP was nearly pointless.
who gave you idea of using alkaline batteries for high current devices? alkaline batteries are not designed for high current, but for longevity so you use them for remotes, which at worst would take 10mA every time you press button and batteries would die of old age not due to discharge from remote for high current you use heavy duty zinc-manganese batteries, which are designed for high current, but do not last long for high current you use Ni-Cd for longevity you use Ni-MH (which is huge rubbish for high current)
WRONG Lithium polymer is nothing much different from lithium ion actually there is no such chemistry as lithium polymer and to make it fair all current rechargeable lithium based batteries are lithium polymer as polymer is a separator you have not spend even 1 day on while thing as all what I have written to just an hour to learn do not make people mistaken by your lack of knowledge in this subject please you guys are great in Computers and I like what you do, but you have tried subject which you should not have touched as you did not prepare for it and it is easy nie complicated then you may think proper tech quickie on batteries would definitely take longer then proper tech quickie about Linux FileSystems I know both subject, so I speak from knowledge stand point, not from what I think only

+Martin J just about 2 centuries off there mate
+jd6133 not quite. Preston Garvey mentions they're pre-war tech, meaning he's more like 61 Years and 5 months off... And likely less, considering how widely distributed they are in the commonwealth.
+Martin J Nah.. Fission batteries FTW
Sean Condon but we dont live in the fallout universe
+jd6133 - Well... true, but you said we're about 2 centuries off as if we WERE in the Fallout Universe. Besides, where were we, technologically speaking, 61 years ago, in 1955, compared to where we are now?

we already can make phones that you only need to charge once a week
you just need to get rid of the thinness craze that we are currently in (thicker phones will also be more durable)
the ulefone power 5 has a 13,000mah battery and can last almost a week on 1 charge, it is thick and heavy (similar weight/thickness to an iphone in a battery case, but more energy efficient) but it is very durable, and the battery will not only last longer between charges, but it will also last longer since you are using 1 cycle per week instead of 4 cycles per day
longer runtimes are possible with current technology, just make the device thicker and include a physically larger battery
imagine the battery life of a galaxy S10 if it was double the thickness, but included a 10,000mah battery (maybe then i could get a whole day out of my S10 5G instead of being tethered to a battery bank if i go out for more than a few hours)
Look at that magnificent specimen in his red shirt. He has a belly and he doesn't care.
Belly bois raise your hands!
Actually there are several battery types that are ready but the prosess is slown down by goverments etc.
There is even a battery you can cut with a scissor etc while in use with no chance of shorting and exploding
I want supercapacitors, i want to be able to fully charge my phone in 10 seconds
+Sci-Twi remember those small leakage currents
+Sci-Twi supercapacitors can provide large amount of current.
if you want to charge your phone in 10 seconds you need a source that can provide a lot of current and have a low series resistance.
+Sci-Twi supercapacitors also can be used to start cars. You could make it a hybrid with a few Li-ion cells. You should not jump to conclusions and say supercapacitors suck in every way. They have their uses.
+Sci-Twi supercapacitors can last for a few million charge cycles without losing their energy storage capabilities as compared to lithium batteries. They can be used for noisy SMPS supplies etc.
think I heard about a film about batteries called secret of nimh
+Eastyy's blogspot Ermagersh, I've never thought of that. Good one!
Luke's hairy armpits at 5:58 made me feel uneasy.
Nice video, and I have used some of your tech quickie videos in my science class in the past and this one will be added to when I talk about batteries. Could you potentially do a video on how the computer power supply works, or the voltage regulators works. Not going to lie it would be great for when I have to cover Ohm's law.
INSTRUCTIONS PER CYCLE AS FAST AS POSSIBLE?????"??
Number of instructions cpus can take in one clockcycle
Done.
I've charged Alkalines before, it usually works but it only gives you like a quarter to half of the battery time that you'd normally get, but if your in a pinch and can't afford 1-6 dollars for batteries well charging batteries seems to work... just watch them carefully.
not charging your phone every night is a thing of the past.....
+Eric W. I remember when battery life of phones was measured on if you can make it through the whole work week between charges...
+Eric W. because modern phones have to be chargedduring the work day to last till the end!!! so twice a day..
I used to play with RC electricial models and I was always sceptical about that "no memory" thing. I used whole bunch of different types of batteries, from NiCd to Li-pol. I always used hi-end, competitive chargers that allowed me to see, exactly how many amp-hours actualy "got into" my battery (it also allows for charge-discharge cycling to regenerate batteries, setting your own charging current and much more fun stuff that taught me alot about batteries and electronics in general). Let me tell you: the better you treat you batteries, the better they gonna last and perform. And it's true for all types batteries, NiMH, Li-ion, you name it. ALWAYS try to discharge and charge them fully. Also, the lower the charging current, the longer the charging (obviously), but also the charging is better and moe efficient with the lower current (more Ah go in) and it's much better for the longevity of the battery. It is reccomended, for the long service of battery, to charge it with the current of 0,1C (e.g 2Ah battery - 0,2A charging current, which gives 10h of charging). Ocasionally, if you hurry you can increase it to 1C (1h charging), but not too often. It's not reccomended to exceed 1C, ever. It's weird to me that these days companies focus so much on performance of the phones, stuff like quick charging, but not the batteries themself. Plus you cannot exchange them easily these days and chargers are crap as always, which creates nothing but problems. And it's not even that difficult to make 5000mAh batteries that are small and fit in the phone (RC people used them for years).
Genuinely why don't they just make the phones thicker and have easily swapped batteries.
you forgot hydrogen ion batteries (which already exist, but require a very expensive proton exchange membrane)
There is no such type battery like what you just mentioned
@@stephensnell1379 yeah, I guess it's technically a fuel cell, but it performs the same function th-cam.com/video/1-yLqwGS2dA/w-d-xo.html
In my younger ignorance I used to put alkaline batteries in a battery recharger and it actually brought them back to life for a couple more days. Maybe it just mixed up what was left who knows but it worked mildly with the more expensive brands and not so much with the cheaper ones.
You actually can recharge alkaline batteries, it just doesn’t work very well

Heard him say "Lithium batteries need to be fully drained", immediately unplugged laptop from charger...
dont. deep decharging a lithion ion battery will kill it. dont.

The largest battery killer is the cathode degrading. Improving the cathode effectively makes batteries more resilient.
Matthew Moore I thought it was DARPA?
I disliked the video only because he let me choose one more time
"last several times larger" 4:36
He said longer
Imagine how long a cellphone battery would last, if unwanted background processes wasn't running all the time.. Juuuust saying.. :-))
5 years later and we are still using lithium :(

Meh, just put in a capacitor and recharge your phone/device in a fraction of a second. /jk
+Yemto but they dont have near the same capacity as a battery
0:20 You unfortunately cant create energy nor can you destroy it. Just a little side note. Nice video though
it is not technically created. Is what he really means is he is transforming chemical potential energy into Electrical, thus "creating" electrical energy and the actual electrical energy did not exist before the reaction happened.
4:40 "Could last several times larger"
Grammar exe. not working
Yooo AP Chem got me knowing these reactions backwards, sideways and blindfolded.
sorry but that was too fast. simply listing the most common battery types is lazy at best. you have to say why you'd use each one too, self discharge, power density, current density etc.
+Thanh Tran That's an in depth analysis of the characteristics of each battery type.
This video was just about the different types...says right in the title.
You also answered your own criticism. "It's too short."
It is quick. That's the name of the channel. "Tech Quickie", not "Full in Depth Tech Breakdown and Analysis."
It is a quick explanation of different battery types as fast as possible.....so I don't understand your criticism.
+Jween Tech I understand the title but sometimes quick is just too quick. People would want to know why one would use different types of batteries and not just list them by chronological order...
If anyone is wondering why alkalines say 1.5v and NiMh rechargeables say 1.2v....
The very short answer is that alkalines drop to 1.2v when under load and NiMh stay at 1.2v under load or not.
The reason why NiMh lasts longer in some devices is that Nimh hold that 1.2v almost uniformly until out of "juice."
Alkalines droop to that 1.2v then continue to gradually droop below to 1.15v....1.1v......on so on until it's dead.
How do magnets work as fast as possible
3:46 why does it say li-ion polymer instead of li-po i.e. lithium polymer?
The proper name is lithium ion polymer.

+FeNite8 You can extinguish them with water - a class D fire extinguisher is not required.
There is a report on this by the FFA.
It's mid-2021 and still no new battery technology. Still the same shit every single new device comes out. Why can't tech companies focus on improving their battery tech first rather than making their phones look like the slim versions of their ancestors back in the ' 70's 🙄🤦🏻♂️
New battery technology is out there and just reading about them they really sound impressive and promising. Why can't the big companies invest on those batteries and try it on one of their devices first. Not only they'll earn money but they'll also be able to help the planet that's dying because of us.
I'm specifically talking about Samsung and especially you, Apple. Because the other tech companies are looking up to you both. Be a good example by showing true innovation that makes a REAL CHANGE. And that's improving your battery technology.
Innovation not duplication.
Graphene battery as soon as possible
i wanna ask...
Does playing high-end games such as GTA 5,CS:GO,Medal of honor: warfighter,etc on my laptop while charging effect my system and battery-life?
Also its a Non-removable battery
im using the Asus A556UR
Ni-Cd are far from obsolete
Ni-Cd provide right in spot balance of high current (Ni-MH is much worse), low self-discharge (Ni-MH is almost twice better), low maintenence (less then lead-acid and even Ni-MH), easy charging (Ni-MH is hardest one ever) and high volumetric capacity (lower then any lithium, Ni-MH but much higher then lead acid)
there is no lift which sits in this spot
I do not think batteries and especially rechargeable batteries are subject for tech quickie
you may write PHD on rechargeable batteries every year for your entire life span and your grand children can pick it up and continue for another lifetime and it won't exhaust subject
Didn't even mention graphene....
OK but why does R/C industry use only Li-Poly while Li-Ion (18650's) are ubiquitous, much cheaper, have about the same charge density and there is usually plenty of room for them ..never had good luck with NIMH on any charger compared to NiCd..
Umm... Luke, the cathode is the negativity charged side and the anode is the positively charged side. Also Li-PO batteries have a lower energy density than a Li-ION battery. Li-ION are also MORE expensive than LiPOs.
5:01 There should be a still from Linus and Edzel's vlog from SDC.
If I connect a 9v battery with half charge to a 2.4v LED it will light but if I connect a fully charged 9v battery to the same LED it burns the LED out. This would indicate the battery only begins as 9v and slowly loses voltage. So a half charged 9v battery should be a 4.5v. Is this correct?
If I connect a full charged 9v battery to 5 2.4v LEDs will it deliver all 9 volts to each LED or will it divide the voltage delivering 1.6 volts to each?
I am using . Will the laptop bypass battery & consume power directly from power source once its chargered 100% ? Provided I am using laptop with adaptor plugged in.Will it effect my battery life ?
You cannot "recharge" Alkaline, but YOU CAN REGENERATE Alkaline ! Each time, the capacity/voltage decrease by a lot, so it's very limited (there is other things to know when you do it too, google it !), but still possible. Remote controllers are happy with this.
Luke you did not talk about watt-hour per kilogram. Which is very important when you are talking about batteries for things such as: Drones, Cars and boats. Or even Wh/L for when ever space is of concern. The latter isn't as important. I the end because of this lack, this AFAP was nearly pointless.
We need Linus As Fast As Possible
who gave you idea of using alkaline batteries for high current devices?
alkaline batteries are not designed for high current, but for longevity
so you use them for remotes, which at worst would take 10mA every time you press button and batteries would die of old age not due to discharge from remote
for high current you use heavy duty zinc-manganese batteries, which are designed for high current, but do not last long
for high current you use Ni-Cd
for longevity you use Ni-MH (which is huge rubbish for high current)
WRONG
Lithium polymer is nothing much different from lithium ion
actually there is no such chemistry as lithium polymer and to make it fair all current rechargeable lithium based batteries are lithium polymer as polymer is a separator
you have not spend even 1 day on while thing as all what I have written to just an hour to learn
