When will AA lithium-ion replace NiMH in stores?

How long do you think AA and AAA NiMH will remain in retail stores?

When will AA and AAA nickel metal hydride be replaced with lithium-ion
AA and AAA batteries?

Thanks.

 

Never because the voltages are too different. The 3.6V (nominal) of a
Li-Ion will destroy most tools that expect the 1.5V of a traditional
battery.
The 1.2V of a NiMH is close enough to those 1.5V for most tools to work
with the reduces voltage, in particular as the actual voltage of
traditional batteries drops below 1.5V anyway after some use.

5-10 years after someone invents them.

 

and how exactly do you know this?

cite a reference for this.

 

That sound about right.

Lithium-ion cells are becoming increasingly popular in a wide
variety of consumer products. Cordless tools are a glaring example.
This stuff is a little bit off topic, but following your lead,
possible is that some lithium-ion cell design/shape will spin off to
become popular in other devices and eventually become popular enough
to replace AA batteries. There's nothing (except the standard) that
prevents any manufacturer of any device from making a battery
compartment and device power requirement that fits a 3.7 V battery.
But again, I agree the timeframe would probably be at least one
decade for that to happen.

If they ever get rolling on improved electric car battery designs,
that will be great for everybody who uses rechargeable batteries.
Hopefully we won't be pacified by the middle east loosening our
chain and forget all about breaking our dependence on foreign oil.
Time will tell.

Good luck and have fun.

 

Be careful. SMS has utilized sock puppets before, and this looks
like another case where he's answering one of his creations. The OP
(who doesn't seem to have ever been here before) suddenly appears
and creates two battery threads, one in which he at first appears to
be a clueless battery newbie, and another in which he also appears
clueless, yet knows about the MH-C9000 and La Crosse RS900 chargers,
both of which are touted on SMS's battery website with this :

and replies in this thread to SMS's bizarre "2018" prediction with

and then continues with two paragraphs sounding just like SMS.

Well spotted asaar - yes, there he goes again. Just check the headers
for the giveaways. I'm surprised it wasn't "Dr Sumner C Roberts".

Have a good one, SMS.

 

Are you in a movie?

Off the top of my head... I posted here about early Energizer an AA
NiMH battery charger, that it wouldn't charge AAAs. Another time I
posted about shopping for an inexpensive digital camera. Another
time I posted about the move from film to digital. And probably
other times. It's a big group with lots of intelligent people.

I have no idea why it matters, Jack, but there you go.

Because I didn't know or forgot to consider the cell voltage of
lithium ion batteries, Jack?

Hello troll.

It's called "research", Jack.

Both of which have been discussed in this group too. So it's not
just SMS, but everyone here is my sock puppet.

As if it matters (to anyone besides the obsessed), my last post's
signature should clear up the issue, unless you are totally drunk.

Good luck.

 

All the resident trolls come out to accuse each other every chance they get.
It's all quite hilarious.

Now, back to something photography related. Something that none of them know
anything about, otherwise they'd be involved in those threads. The moment they
do enter actual photography-related threads their ignorance and net-only life is
instantly revealed. It's why they can't participate in those topics.

The best they can muster is knowing the mAh required for their vibrators. Of
this they are quite certain, and won't be easily revealed as the know-nothing
trolls that they are.

 

As I said, you appear to be clueless. With all your research into
batteries and chargers, you don't know Jack. I didn't say that you
definitely were SMS's sock puppet, but there were indications that
you might be one, which I mentioned already. If you aren't, then
you also don't know much about SMS.

As per my reply in your other thread :

Both of the above are excellent chargers, but are unlikely to be
of much help. It's extremely unlikely that your current charger
(pa!) is killing your cells. They may show that your NiMH cells are
losing capacity more quickly than normal, but you know that that's
happening already. Focus instead on how you use your NiMH cells.
If you have a pool of NiMH cells that are shared among devices, stop
doing that, at least until you're able to determine what's damaging
your NiMH cells. It may be only one or two of your devices that are
damaging them, so if in the future you use known good NiMH cells and
use each set in only one device, you'll be better able to pinpoint
the device that may be prematurely damaging them.

Each device treats batteries differently. Some are (whether
intentionally or not) designed to shut down when the first NiMH cell
is depleted. This helps to protect all of the cells in that device.
Others can operate at lower voltages, and can continue operating
when one cell is completely exhausted, which will rapidly shorten
that cell's life. Devices that are much more likely to damage cells
are those that use 3 or more cells (the more they use, the more
likely they are to damage cells), and analog devices such as those
that contain motors, non-digital radios, flashlights that use bulbs
instead of LEDs, etc. In digital cameras that use 4 NiMH AA cells,
it's prudent to recharge them before the battery warning indicator
gives you its first alert.

 

Sorry about that, there's so many trolls and sock puppets in this group
lately, and this question has been posed so many times, that I
mistakenly assumed the worst, especially since you're using a pseudonym.
I apologize.

In reality, AA _sized_ Li-Ion cells _do_ exist already. The problem is
that they aren't interchangeable with standard AA cells except in
limited circumstances (where the device can accept higher voltages due
to internal switching regulators with a wide input range). You need to
use a charger designed for them. Obviously these cells need to be
marketed very carefully, but some of them do have internal protection
circuitry to protect against fire or explosion (but they would still
damage many AA powered devices).

If you go to the battery information web site there is more information
about these batteries. Here is an except from the site:

"AA sized Li-Ion cells do exist, but please don't call them AA cells!
The designation is 14500, and they are relatively inexpensive. They have
protection circuitry built in. They need to recharged in a Li-Ion
charger, and the voltage is 3.7V, so they are not interchangeable with
"stnadard" 1.2V to 1.7V AA batteries, except in some devices that have
internal switching regulators. For example, many high end LED
flashlights have internal switching regulators that can accept a wide
range of voltages (they can run off one or two stnadard AA batteries, or
a 3V CR123 battery, or a 14500 battery). In terms of capacity, there is
a slight advantage with these cells, versus low-discharge NiMH cells; a
3.7V, 900mAH cell yields a capacity of 3.33WH, while an AA Sanyo Eneloop
yields a capacity of 2.5WH."

There are links to sources for these batteries and chargers on the web site.

To get to the battery information web site, type "nimh versus li-ion"
into Google's search window and click on "I'm Feeling Lucky" and it'll
take you right there. The direct URL is "http://batterydata.com/".

 

Yet AA size Li-Ion cells that produce 3.7 volts are already being
marketed at the retail level, but they do have protection circuitry

 

My Garman eTrex Venture HC GPS frequently asked questions page suggests
they are marketed someplace.

"You do not want to use the lithium ion batteries in our units, because
they will permanently damage the unit."

 

....

As if I should have included a disclaimer because a reply author is
using the same legitimate ISP for posting to USENET.

Oh well. I've seen other posters who think they are King Protectors
of the group, who had no idea what was really going on, like you
and your obsessed friend, Don Quixote.

 

Wow, everyone here sure is behind the times... we were putting Energizer
AA lithiums in a battery-hogging little Olympus digital camera, like, 10
years ago. Energizer has at least two non-rechargeable AA lithiums on
the market:
http://www.energizer.com/products/hightech-batteries/Pages/high-tech-batteries.aspx

At the time, they ran about $20 for a two-pack, but lasted up to 10
times longer than alkalines in that camera, so it was worth the cost.

If you are not him, I genuinely apologise...! But, "John", don't *you*
think it's just a remarkable coincidence? It's a funny old world, when
two totally different posters use the same host/timezone, are both
intensely interested in batteries and chargers, name the same devices,
and that one of the said posters has a proven history of posting as
sockpuppets asking hypothetical questions to drum up traffic to his
oh-no-it's-not-commercial websites?

You'll note I posted but once. I am only responding now as you have
decided to talk to someone who is obsessed. In future it might be
better to ignore folks who have 'no idea', like me.

Oh well. I've seen other posters who abuse usenet, like SMS, D-Mac, and
Vern/Keoeeit, and I like making sure newbies know what might be going
on. If I miss occasionally, so be it. Sorry.

If you are not SMS, I'm sure your future posts will demonstrate that
adequately, so why worry yourself about my 'wild' guess? You may also
wish to judge me by looking at other posts too.

I don't always 'out' people...

 

That's why g-d invented kill-files.

 

No, he didn't ask about lithium AA batteries, he asked about LiIon
rechargeable AA batteries.

 

Google "14500 battery." No, you can't buy them at Wal-Mart or Target,
but all the specialty battery sellers have then available. These usually
aren't simply raw cells, they at least have protection built in against
improper charging.

I sure wish that they wouldn't even use the term "AA" when referring to
these batteries, though I'm sure that they provide sufficient warning.
