Have you guys notice, that the ebay AA, AAA 1.5 V Lithium Ion
battery
listings(in China) is no more?
Must be licensing violation issues or something??!!

Still there's no shortage of 18650 & 14500 Lithium Ion (3.7V) and
other
ones.
It's the AA, AAA 1.5V Lithium Ion ones are the real deal, if they can
be
found.

Found this one, but no retailer.

Found this, but ridiculously expensive.

http://www.aliexpress.com/store/product/4-pcs-lot-1-5V-AA-2800mAh-Lithium-ion-polymer-Rechargeble-Battery-Powerful-and-stable-voltage/314368_1113756150.html



Interesting, but read the specs carefully. The battery casing, and the
spec, shows capacity quoted as 2800 mWh at 1.5 volts. Thats actually
only 1870 mAh.

Yes, and the silly price tag.


Mind you, mWh is actually a more useful unit, since it measures the
total energy, rather than the current * time. On that basis, a typical
2500 mAh NiMH battery has an energy capacity of 3000 mWh, assuming it
delivers 1.2 volts over the full discharge ( not quite true, but
close ).

I assume its in fact a 'normal' 3.7 volt lithium cell internally, with
a buck converter holding the output voltage at 1.5 volts - neat.

What the technical difficulty behind producing a plain 1.5V Lithium Ion
cell?

The cell produces 3.7V

That's great Rod. You're telling me what I already know.

You obviously don’t if you ask that question.

Why does it has to be 3.7V with a buck converter?

Because the cell produces 3.7V

What can't it produce 1.2 - 1.5V?

Because it’s the chemistry that determines the voltage it produces.

Like this,
http://cgi.ebay.com.au/ws/eBayISAPI.dll?ViewItem&item=151224921170

That isnt the cell, that is taking what the cell produces and
adding a buck converter to it to get the voltage you want.

Certainly good for cameras, which often cut off at around 1.2 volts,
leaving an NiMH cell still well charged.

That's the reason I need them for. But, way way too expensive.
They have 3.7 V AA batteries, dirt cheap on ebay.
But, without a voltage regulator built in, it would cook the camera.

But bear in mind you appear to need the standard LiIo charger, with
current limiting and precision cutoff at 4.2 volts, rather than a
bog-standard NiMH charger.

Yes. Having AA, AAA Li-Ion battery means, investing in a suitable
charger as well.


Certainly the ability to hold 1.5 volts over the full discharge, and
the long shelf life, make it attractive, even at the price. If you
really get 1000 charge cycles, thats even better, since NiMH is more
typically 500.

Nope. Look at the price tag.
http://www.aliexpress.com/item/2-pcs-lot-1-5V-AA-2800mAh-Lithium-ion-polymer-Rechargeble-Battery-General-purpose-for-Camera/1113454194.html
And it's from China. May not be as good as the Japanese one below, but
no price tag on Japanese ones.
http://www.alibaba.com/product-detail/New-Green-Energy-Water-Battery-eco_146017575.html
They appear to be different sort of technology. Some sort of water
adding green tech battery.
I bet the Japanese ones are far more expensive than the Chinese ones.

It's horrendous. NiMH is far cheaper to have,
Can buy a huge bunch of NiMH with a charger(s) for the price they're
asking
for those AA, AAA 1.5 Li-Ion batteries.

I wouldn't worry about batteries lasting 20 years. We lose them long
before that.


In thinking a bit more about that, I wonder... My understanding is that
LiIon gets best life when cycled between 95% and about 50% capacity.

Yes.

Discharging further than 50% rapidly reduces the cycle life.

Stuffs them up indeed.

But because this battery holds up the voltage right to the end of
discharge, you are likely to use it right to the end, and hence
discharge it well below its 50% point.

The device you use them for, suppose to control that.(Camera, etc),
hence minimizing the over discharge damage.
But, a something like a simple torch won't do that and will reduce the
lifespan of these Li-Ion AA 1.5 V batteries.
Besides economically it doesn't make any sense to spend this much money
on these batteries to use them, just for a
torch.

** To a blind, retarded fucking shit for brains CUNT like you -

Still doesn't explain, Mr. nice old fella

It's more like the appliances made to work with 1.2 V, instead of 1.5V

** Not one device has ever been made to work with 1.5V minimum per cell.

Are you sure?!

Your monumental ignorance is only exceeded by you monstrous arrogance.

Still doesn't make any sense old fella.

The regulator comes in handy to handle the excess 0.3V(XXX) with the
alcaline ones.

** Says a colossal, lying fool who cannot read, think or even use Google.

Step down voltage regulation aint' intended.
Torches, lamps, etc we use with NiCDs, NiMHs, don't whinge about the lack

** ROTFL !!!

The fool has linked a " Lithium Iron Disulphide " cell - a non
rechargeable chemistry same as Energizer "Lithium" cells.

There are a whole bunch of Lithium based cells that are non
rechargeable:

http://en.wikipedia.org/wiki/Lithium_battery

The common rechargeable ones are "Lithium Ion" and " Lithium Ion
Polymer".

FYI:

The internal electro-chemistry sets the terminal voltage.

And " ye canne change the laws of chemistry " too.


Thanx man. That was absolutely stupid. I should learn to read.
I presumed they're rechargeable 'cos Lithium+Ion.


** FFS - YOU need GLASSES !!!!!!

It says: " Lithium IRON " !!!!!!!!!!!!!!!

You don't believe me about the misleading listings.
Check this out.

http://www.ebay.com.au/itm/12-Volt-200Ah-Lithium-Ion-Battery-/111272634127

Its not that misleading given that even the title says what it is.

You don’t need any regulator for that, just allow the device to work fine

Try that again in english instead of gobbledegook.

Torches, lamps, etc we use with NiCDs, NiMHs, don't whinge about the lack

Neither do well designed electronic devices either.

> It's that some of them shit themselves when above 1.5V max is given.

Very few actually do.

So, teh torches, etc are happy with 1.2V, 'cos the extra current comes
with NiCDs, NiMHs is handy.

They are actually current devices, not voltage, with leds.

Yep. Just read some of the related chemistry and got myself enlightened.



Hint: Cells are not electronic components.

Couldnt get that hint.
Would you care to elaborate?

Just did.

Yep, They are chemical piece of shits, that was invented to screw the
shit out me. ;-)

** Wot a staggeringly stupid question.

Ever see a 1.5V NiCd, NiMH or SLA cell ?

I see heaps of 1.5 NiCD, NiMH Batteries.


** You are a damn liar.

How so?!

What do you call the 1.2V NiCds and NiMHs we use.


** 1.2V rechargeable cells is what they are.

A 4 cell pack is called *4.8V*, a 6 cell pack is called * 7.2V * etc.


Ok, I get it. 0.3 V difference means a lot to you! right?!


** The fact they are * not 1.5V * has been a sore point with uses ever
since NiCd and NiMh cells first appeared.

Not such an big issue nowadays, as most battery operated electronic items
have voltage regulators built in - so they are equally happy with 1.2V
as 1.5V.

Doesn't explain a damn thing.

** To a blind, retarded fucking shit for brains CUNT like you -

nothing has any meaning.

It's more like the appliances made to work with 1.2 V, instead of 1.5V
minimum.

** Not one device has ever been made to work with 1.5V minimum per cell.

Your monumental ignorance is only exceeded by you monstrous arrogance.

The regulator comes in handy to handle the excess 0.3V(XXX) with the
alcaline ones.

** Says a colossal, lying fool who cannot read, think or even use Google.

Step down voltage regulation aint' intended.
Torches, lamps, etc we use with NiCDs, NiMHs, don't whinge about the lack
of 0.3V(xxx).

** You saw the word "electronic" in my post - didn't you ?

Of course not - since you have wanked yourself TOTALLY BLIND

I assume its in fact a 'normal' 3.7 volt lithium cell internally,
with a buck converter holding the output voltage at 1.5 volts -
neat.

What the technical difficulty behind producing a plain 1.5V Lithium
Ion cell?
Why does it has to be 3.7V with a buck converter?


** Wot a staggeringly stupid question.

I see heaps of 1.5 NiCD, NiMH Batteries.

No you don’t, you actually see heaps of people
claiming those are 1.5V when they are not.

You are right. I didn't take 0.3 V difference into account.


No ?

I don't care about seeing a cell.

You said you did with the original question.

I was just being figurative.
Just desperate to see a 1.2 - 1.8 V AA, AAA rechargeable lithium ion
battery.
Ain't gonna happen, right?

Correct. The best you will ever get is a standard 3.7V cell with a buck
converter.

And a one with a 'built in' buck converter won't be the standard AA, AAA
size, right?

No reason why they cant be.

Just need batteries, and if the battery happens to be a single cell,
I'm happy with that.

But that can only be done with the buck converter you
said you don’t want.

It doesn't sound like I have a choice, now, do I?


Wonder why ?

All the time.

That’s what he said.

The regulator comes in handy to handle the excess 0.3V(XXX) with the
alcaline ones.

You don’t need any regulator for that, just allow the device to work fine
with any voltage from 1.6-1.1V

Step down voltage regulation aint' intended.

Try that again in english instead of gobbledegook.

The best I can do.

Even you can do better than that.

> I do invent terms at times, but should not be too hard to get the point.

Still haven't got a clue what you meant with that sentence.

Torches, lamps, etc we use with NiCDs, NiMHs, don't whinge about the
lack of 0.3V(xxx).

Neither do well designed electronic devices either.

Key word is 'well designed'.

Its most of them now in that respect.

It's that some of them shit themselves when above 1.5V max is given.

Very few actually do.

That 'cos mobile phones, tablets, etc come with voltage regulation.

No, its because very little in the way of electronics is that sensitive
on the supply voltage.

But, there are enough electronic devices out there, that are sensitive to
excess voltage.

Not by that small an amount.

So, teh torches, etc are happy with 1.2V, 'cos the extra current comes
with NiCDs, NiMHs is handy.

They are actually current devices, not voltage, with leds.

That is a total misconception and fundamentally incorrect statement.

Nope. They work on current, not voltage.

> Current and voltage are directly related.

Not with leds they aren't.

These were two measuring concepts created at the time of coming up with
Ohms law.

Ohms law doesn’t apply to leds.
