"Genuine OEM Energizer Ultimate" from eBay

So I bought 4xAA and 4xAAA "OEM Energizer Ultimate"s from eBay (for future reference: dealer is shinee2010).

They are really light and they all read ~1.75v (I'm not at home so I can't weigh them or test them otherwise).

How can I test their capacity?

I can test the current they deliver and see if it follows the curves that Energizer shows for the Ultimates, but other than that - Can I try a discharge in my AngelEyes charger? Will it reject the batteries or report incorrect capacity? Will it explode?

Seems like a good deal to me, but I dont know what it is lol. Lithium batterys with 1.5V? I didn't know thats exist. Looking forward for some information.

Edit: oh I guess they are not rechargables.. damn! So don't put it in your charger Wink at least I wouldn't

thanks for heads-up! Here, lithium primaries are around 2EUR/piece, so might just test these. Not far fron the price of alkalines, surely these cannot do worse...

Very interesting. From what I've been told Energizer had a patent on the AA primary "advanced lithium" and "ultimate lithium". Just like everything else, It was only a matter of time before someone, somewhere got around that. I would love to see a test of these compared to the real thing.

Really would want testing .. [ Quote = They are really light and they all read  ] 

Light weight is usually bad , High capacity usually = density or weight , or heavy !  - I read this as a warning !  

 Always remember , the easiest thing in the world to do , is to expel hot air from your lungs and through some vocal chords ..
The resulting sound may , or may not be worth listening too ….

Since they're lithium based, they should be very light compared to an alkaline.

Agreed.

I have some poor quality batts (not even alcaline, coal-something??), which are lighter than better, alcaline batts.

Energizer Lithiums on the other hand are even lighter, than poor quality primaries. Still, they are superior in use.

 

Maybe I order one 4-pack to check these out. Too bad I cannot test them properly.

Correct.

With my Quark AA2 (R5) on Max, runtime results:

Duracell regular 50 min

Energizer regular 1:10 min

SkyRed    2 min  (light&cheapest possible)

Sony 2500mAh (NiMH)  1:24 min

Energizer Ultimate Lithium L91 2:44 min !!!

 

Energizer Lithiums are absolutely superior.

This flashlight is regulated and it just instantly reduces the light output when not enough "juice", it doesn't decreases in output. So the results at spot on.

 

I wonder how these "OEM" ones are. Maybe I'll buy a set and compare the results.

Lithium primary (L91) is lighter than NiMh and Alkaline. You can feel the difference in weight by hand. Smile

Ordered on set of 4x AA.

 

I believe there is somewhere a quite accurate runtime chart from

Zebralight SC51 with L91 Energizers? Does anyone find it?

I could do a runtime test with Zebra, since its about the only quality AA light that I have and which I believe has quite constant quality and good regulation for Li-ion primaries also.

Yep, thanks!

It seems, that with H1 brightness starts to drop very early.

Maybe it would be better to use H2, would be easier to notice decreasing with bare eye.

 

Since I believe this test is quite accurate, might just test with one OEM and do a rough comparison.

I made a few measurements on these batteries. I couldn't do a discharge test with the AngelEyes, so flashlight tests will have to do.

Energizer Ultimate datasheets for reference: AAA - http://data.energizer.com/PDFs/l92.pdf, AA - http://data.energizer.com/PDFs/l91.pdf.

The OEM Ultimate weights: the AAA weigh about 7.2g each (three are 7.2g, the fourth is 7.4g), the AA weigh about 14.7g each.

For comparison, Energizer states that the AAA should weigh 7.6g and the AA 14.5g.

The AAA and two of the AA are about 1.8v, the two other AA are 1.7v.

They give very nice current through them - I tested first on the junk DinoDirect free flashlight which is a 2AA with generic LED and a boost driver, and it draws about 1.8A with crappy alkalines, 3.2A with GP ReCyko+, and 3.5A with the OEM Ultimates sagging very quickly to 2.98A from there dropping very slowly. The voltage of the batteries dropped to about 1.6v after this short test. Next, I did a 1 minute test during which the current sagged from an initial 3.2A to 2.7A, and the batteries which started at about 1.65v almost didn't drop voltage - they ended up at 1.6v. I didn't run any long test as the junk DD light just gets warm too fast - after the 1 minute test the host was about 35 degrees C and the light over 42 C (from an initial 30 C). Energizer states that maximum discharge rate of the Ultimates is 2A, so the above readings are about 50% higher than the specs... very strange.

Next, I tested the AAA with my Manafont Ultrafire 3-mode XM-L inside a Solarforce L2i host. Fresh crappy alkalines gave 0.8A on high. GP ReCyko+ gave 1.2A. The OEM Ultimates gave 1.6A which quickly sagged to 1.4A. Combined voltage dropped from 5.3v to 4.8v. A 1 minute test resulted in constant 1.4A current throughout the test, and combined voltage dropped from 4.8v to 4.7v. The 1.4A current is very close to the max discharge rate stated in Energizer's datasheet of 1.5A continuous.

So all in all, I'm quite impressed with these batteries.

If their capacity is as advertised, they are extremely good buys for primaries and much cheaper than the Energizer branded version.

A few more measurements:

MF UF XM-L in L2i with 3 eneloops: 1.8A

Akoray K-106: Alkaline - 0.7A, GP ReCyko+ 0.8A, OEM Ultimate 1A but sags quickly to 0.9A.

I've also measured lux @ 70cm: XM-L with eneloops: 15000 lux (1.8A 4.2v), with OEM Ultimates 10000 lux (1.4A 4.8v).

Akoray K-106: Alkaline - 1300 lux, ReCyko 1600 lux, OEM Ultimate 1900 lux.

I don't have any AA eneloops so I can't test whether they are brighter for the Akoray.

I don't, and they are quite expensive here.

They sell them 2 for 10$... But maybe I'll buy some out of curiosity. Then again, maybe not.

Damned expensive - lithiums are .. 

If these offer decent performance - they could be good ...[ A lithium test would cost more than a bunch of flashlights ! ] 

Can they be discharged in a Hobby charger [ dont see why not ? ]  

 

 

What the hell ! , $4.20 shipped - ordered a 4 pack of AA - Will try and discharge one with the hobby charger or Powerex

Heyyy, good idea.

Have for some reason tried to discharge primaries but Maha says Resistance too high.

Energizer Lithiums seem to work...

 

Any suggestions about what discharging current should I use? Smile

Got some genuine Lithiums hanging around, OEM´s are not here yet.

 

 

Edit: started now. Discharging @100mA, starting voltage 1,783V. Exp.: 03-2023.

Just had a idea... Could these be just outdated Energizers without a date stamp?

These are marked in the listing as expiring on 2024, which means 13 years shelf life.

Energizer states 15 years shelf life (at 21 degrees C).

But in the stores I see Ultimates with '23, '24, '25 expiration year, selling at full price, so I don't think half price (or less) can be attributed to a few years less shelf life.

Here's some weights of various cells I have:

AA Alkalines:

Duracell - 24.7g
Sony - 23.1g
GP - 23.0g
Ikea - 23.2g

AA Rechargeables

Sony Cycle Energy - 27.1g
Sanyo 2500 - 29.5g
Samsung 2300 - 28.3g
Dynacharge 1800 (duracell) - 26.3g

Energizer E2 - 14.9g

I wonder how well those blue AAA's perform as I've never tried AAA E2's. Frankly, I've never seen them before.

Yep, true.

Again, have these even been on market for 10 years yet Big Smile

Just to make a note, also 8-pack seems to be available from same seller.

These are blue, wondering if there´s difference?

I don't think the color matters.

I think he gets them in random colors. He contacted me after he sent me the batteries to apologize for sending a different color than in the pictures (I think one of them was advertised as grey).

Anyway, there's another seller who shows all kinds of colors for his batteries: http://cgi.ebay.com/4-Energizer-Ultimate-Lithium-AA-Batteries-OEM-Wrapped-/280686213838?pt=US_Batteries&hash=item415a33bace Smile

As a regular user of Energizer Lithium Ultimate AA batteries as a backup for photo flashes I'm really interested in the performance of OEM Energizers.For now I have a stock of retail Enerizers so I don't thimk I'll be buying them anytime soon. As for the price of Energizers I found them on sale at a local store for 2,99€ per pack of two batteries (AA that is)

Now I see

Wow 2 pack for EURO 2.99 is a pretty good deal.
I found the 4 pack in Holland about 5 months ago for 5 euro.. on sale...

lowest Ive seen them in Holland...

Here in Japan I have never seen them for a good price.

Here in Finland I once saw them about 1€/pcs in packs of 6. Bought only one...........

Regular price is I would guess around 2€/pcs. So, this eBay price is indeed very nice!

Today I saw the lowest price on alcalines ever, 1€/4pcs, about 1,45$ for 4. Regular price for good alkies is about 2+€ -> 4€ /4pcs. 

 

If I compare these OEM-Energizers to regular priced alcalines, I would say there´s pretty much no point AT ALL to use a single alcaline any more for these prices.

I tested the original Energizer with MAHA to get reference.

When discharged at 100ma, I got 3062mah from it with ending voltage after a while 1,350V.

After this, I got usable light on SC51 and Low2 mode for 2 hours. Then voltage was some 0,6V.

 

 

will post when I get OEM´s. It will take some weeks, I guess.

OEM´s arrived.

Initial voltages: 

1,819V

1,775V  -> discharge test @ 100ma

1,781V

1,882V

 

So, I´m now doing discharge on the worst one to see, what I can get out of it.

Quite a bit variance in there...

15min discharge behind and cell is already at 1,34V. Original took half-a-day to get there so it´s not looking very promising.

 

1,815

1,816

1,811

1,812 Were the readings from a pack of original Energizers.

 

From what I can tell from + and - ends, positive end looks just like in Original Energizer.

On negative end, there seems to be very faint "brush" on the surface. You cannot notice this unless you try to do like a reflection with them. OEM´s negative end is more matte in finish.

 

Will post more soon.

Propably will also order more soon, to test or use as a budget batts Smile
