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.
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).
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)
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.
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 :)
I bought several of these from different sellers from ebay and tested one, it seems to be genuine as it did more than doubled the runtime of eneloops in my D10.
D10 R2 on High
Regular Alkaline: 25mins
Eneloop: 40mins
Energizer Lithium AA: 90mins
Well, at this point I would say at least that these are Lithium based for sure, low price, probably high performance batts. Might have more variance in specs than originals but what the heck, for this price? :)
I might try a really short duration short-circuit test with these and genuine Energizers, to see, if there´s any difference in initial amp draw.
According to Energizer's specs sheets that's where the lithium primaries really show an advantage over the alkalines (should be the same 3000mAh, but alkalines drop from ~2800@25mA to ~1000@1000mA for AA).
I think I'll order some more AAs and AAAs now... :)
