Someone has a new toy!

Not sure about those abyssmal discharge capacities, though. The RS cells are basically rebadged Rayovac Hybrids, I believe.

I gotta say, those are some craptastic batteries

The 10A06 AAs look OK after Break-In. The 10A06 AAAs are going to need some more 'encouragement'...

How are your's doing?

Check back in a few months, after they get a few cycles on them. Remember, '10A06' - they've been 'Couch Potatos' since October 2006 (27 months)! :sleepy:

I'm not as up on the details as you, but, at 75% discharge per year, 75% of 75 is 56.25% (AAA: 422mAh, AA:1125mAh). The AAAs are in the ballpark but the AAs are OUT PERFORMING! :twothumbs

OK, I think I see where the confusion may be. The way you present the entries in the tables somewhat implies chronological presentation of the testing. As such, it appears you first did a break-in on the AA's and got about 1883-1950 mAh, but then you did an additional discharge at 400 mA and got only 305-1323 mAh. Did that mislead you also, Mr. Happy, or was it just I? Or, was the order of tests clear to you, but your "craptastic" comment was aimed at how the AA cells remaining capacity out-of-package were wildly varying?

In that regard, TTA, in terms of LSD performance, I would be more concerned about the AA cells. Even though the AAA cells came out lower than rated, at least the AAA cell capacities out-of-package were all very close... nothing like the AA's from 303-1323! (That is, of course, assuming all the AA cells got equivalent charge at point of manufacturer, which I guess should be a safe assumption for any LSD.)

 

[Mr Happy]

I assumed from the order the results were presented that the discharge was done after the break-in. And for the discharge results to be less than 2/3 of the break-in capacity, in some case much less, indicates very poorly performing cells.

However, if the discharge was done first, before the break-in, then the results would be a little less at variance with expectation.

And I am assuming not only was the discharge done first, but it was done straight out of the package, before any initial charge was given.

my 11a06 cells were fairly uniform at about 1450 out of the pack and around 1915 after a few cycles.
thats good in my book.
they are getting a daily pounding in a modded arc ls.
i carry 1 set in the light and 1 set as spares.
they get rotated as i use them and have the same number of cycles now.
probably at least 25.
time to do another discharge test.

Sorry. I'm accustomed to reading and writing 'New-to-Old', 'Top-to-Bottom'. I just 'assumed' everyone would realize that by the values.

...Or, was the order of tests clear to you, but your "craptastic" comment was aimed at how the AA cells remaining capacity out-of-package were wildly varying?

In that regard, TTA, in terms of LSD performance, I would be more concerned about the AA cells. Even though the AAA cells came out lower than rated, at least the AAA cell capacities out-of-package were all very close... nothing like the AA's from 303-1323!

That was explained in the NOTE(s) directly under the table.

You bought a few packages - how are your's doing? Any data to add to the thread?

I'm in the middle of some other testing, and impending surgery, but maybe after I can run some for fun. They haven't seen much use since I got them several months ago.

 

[Hoggy]

TTA - you may want to re-order those results. Because, like others, I thought you did the break-in first and THEN the discharge.

That had me worried, because I rather like my ROV Hybrids! They're all that's available locally at Woodman's grocery stores in SE Wisconsin.

Here, Walmart only sells LSD's with a charger - Kodak pre-charged, last time I checked. So the only choice I have is getting ROV Hybrids at Woodman's or ordering online. :shakehead (CC has been fresh out of Eneloops for a LONG time here.)
