Sanyo Harmolattice Low Capacity NiMH AA Cell - A Comparative Abrams Tank?

[Bones]

As noted in a prior thread, minimig recently posted these images of a 1000mAh low self-discharge Sanyo cell which appears to be a genuine sibling to the Eneloop:




I can't help but think this new cell is probably built like an Abram's tank, and should be capable of withstanding far more abuse than virtually any other NiMH AA cell out there.

In addition to its advertised use in low drain devices such as remotes and mice, could it also be a viable replacement for ni-cads in solar powered garden lights and constant charge devices such as electric razors and toothbrushes?

As well, it seems an ideal cell for use with relatively low-powered solar chargers far from the beaten path.

Or it already obsolete...?

I wouldn't mind getting my paws on some of those to try.

A lot of the NiCads in my solar lights are failing this year - would be worth trying out to see how these ones work compared with another set of NiMh cells I have in some solar lights.

EDIT: This super-lattice alloy is not new...found a Sanyo article from 2003 that talks about it. The Sanyo 2700 mAh cells use it.

Re: Sanyo Low Capacity Super-Lattice Alloy NiMH Cell - A Comparative Abrams Tank?

As noted in its initial press-release back in November of 2005, the super-lattice alloy is also used in the the Eneloop Black Rose:

The synergy of the following proprietary technologies of SANYO in developing high capacity products has made the successful development of 'eneloop' possible:

1. High-performance negative electrode 'superlattice alloy'.
2. Make-up of battery material and battery plates.
3. Maintain quality despite being out of use for a long time.

These are a few of the technologies that have helped contain self-discharge during the period for which the battery is not in use. Furthermore, it also inhibits voltage reduction even after a long period of being out of use.

It's hard to believe that the Eneloop has been on the market for almost four years now.

Anyway, the Eneloop's proven durability with its 2000mAh capacity utilizing Sanyo's super-lattice alloy should bode well for this new low self-discharge cell, especially with its mere 1000mAh capacity.

Thanks for sharing, I didn't know they even existed, I will have to try some for sure, as I like the Eneloops more than any other NIMH cell!

Like i mentioned in the energizer thread, i've seen these locally for quite awhile now but have not been able to find any information about them.

They cost the same as the chinese GP Recykos (and hence just slightly less than eneloops). So i'm not inclined to get them until further study is made of them.

Re: Sanyo Low Capacity Super-Lattice Alloy NiMH AA Cell - A Comparative Abrams Tank?

Are these not available in the US or something? I have never seen them. Same goes for the GP Recyco. Never seen or heard of these outside of this forum.

ps. Recyco is that pronounced RE-psycho or RE-sicko? Either way it is an odd title for a battery, conjuring up disturbing mental images.

As far as I can tell they are only available in Malaysia and Singapore (and Japan?). Maybe they will become more widespread in the future.

Recyco is meant to remind you of recycle of course. They also are rare in the US, but I saw loads of them in England.

So it IS pronounced RE-PSYCHO. How disturbing... Norman... this is your mother..... stab stab stab....

Re: Sanyo Low Capacity Super-Lattice Alloy NiMH AA Cell - A Comparative Abrams Tank?

i've banned all GP batteries forever due to its irresponsible manufacturing process which have already poisoned a lot of its staff (something to do with the chemicals):thumbsdow:thumbsdow:thumbsdow

they're super cheap & are in nearly *every* supermarket/drugstore here in Hong Kong..

most people here buy Eneloops AFAIK, which is around US$10 for a pack of 4AA/AAAs~~

Re: Sanyo Low Capacity Super-Lattice Alloy NiMH AA Cell - A Comparative Abrams Tank?

I've been digging around for a little more information on this cell, and determined that Sanyo has also released an 600mAh AAA version.

As shown on this chart from Sanyo.com, it bears the model number HR-4UQ, whereas the AA cell bears the model number HR-3UQ:

Incidentally, after almost having an accident when I first noted the 6000mAh capacity of the last model listed on the chart, I realized it was the Eneloop D-cell.

 

[Bones]

Oops...

 

[Bones]

As with the Eneloop, Sanyo is publishing reams of information about their new Harmolattice.

PDF specifications for the HR-4UQ (AAA) cell:

PDF specifications for the HR-3UQ (AA) cell:

http://battery.sanyo.com/en/spec/twicell/HR-3UQ.pdf

PDF charts of the discharge characteristices of the HR-3UQ:

http://www.eneloop.info ... discharge.characteristics.3UQ.pdf

As shown in this excerpt, the Harmolattice easily hangs with with the Eneloop insofar as its voltage is concerned:

Try to write it right first lol.... ReCyko.

For those who wonder whether their cells will benefit from a 'few' break-in charges, it's notable that for this new cell, Sanyo specifically carried forward and adapted the following blurb from their specifications for the Eneloop:

[Turbo DV8]

I notice the package doesn't even try to claim "New & Improved," just "New." The only thought that crosses my mind about these "new" cells is, "What's the point?" It's an answer to a question that nobody asked. And if the relevance of these eludes me, what angle does Sanyo plan on using to differentiate and/or elevate these from Eneloops for the masses? All I can see is getting half the capacity for perhaps just a tiny bit less money. The only advantage I can see over the Eneloop is that they create a "harmonious lifestyle," which I am all for, of course.

 

[SemiMan]

Going to go out on a limb and say these are just "cheaper" Eneloops. "Up To" 1000 recharge cycles is just what it says for Eneloop.

Look at the weight differences between this new one and the Eneloop. The new one is quite a bit lighter.

Hence, I have a feeling, which could be wrong, that mainly these are batteries with less material in them.... perhaps targeted at lights, etc. where the storage needs are not as high.

Well, it's all about "thinking GAIA" - harmony, ecology, CO2 emission reduction, conserving the planet for future generations, nothing else.

I haven't seen these batteries anywhere but I think they will probably cost around half the price of the Eneloops. They will be sold either in the same markets or targeted to developing countries. Sanyo wants their rechargeables to eventually replace dry cells so they need something cheaper than Eneloops. These low capacity models will also be used to fight with LSD batteries sold by other manufacturers.

What's even more interesting than the break-in, since we all know it's good, is the Internal Resistance after discharge to 1.0V. I've read all through this forum, the ones at rcgroups.com and I don't remember seeing a manufacturer state it so clearly. Is this the correct way to measure IR?

25 milliohms @ 1.0V is a short-circuit capability of 40A.

I would suggest, on that reading, that
a) these cells should NEVER be flash-amped (not if you value your meter!)
b) they sound interesting for hotwire use...

 

[Mr Happy]

25 milliohms @ 1.0V is a short-circuit capability of 40A.

That 25 milliohms is the 1 kHz AC impedance though. It is likely to be nearer 50 milliohms DC. Even so, that is a pretty good value.
