Thats an interesting idea, I might have to give that a try. Will the water balls hold up to high velocity acceleration out of the pouch?

P.S. Why do you need so many AA batteries?

Is there such a thing as having to many? The more the better... so you can line them all up and number them from 1-1000. When they’re all finally dead, they'll make great slingshot ammo.

Wtg for the discharge results which will give a more accurate result for their capacity but its looking good. Wish I had spent extra and just got the xx instead of the standard eneloops. I have 12 coming and I dont think I really need them.

I just got done with the 100ma discharge and these numbers look a lot more normal too me. 

100ma discharge:

1.  2480 mah -- ICV = 1.48v

2.  2489 mah -- ICV = 1.47v

3.  2495 mah -- ICV = 1.47v

4.  2485 mah -- ICV = 1.47v

5.  2483 mah -- ICV = 1.46v

6.  2441 mah -- ICV = 1.47v

7.  2465 mah -- ICV = 1.47v

8.  2462 mah -- ICV = 1.45v

ICV = Impedance Check Voltage

So now I just started the break-in which should take about 40 hours or so.  I'll post these numbers as soon as it's done.  Stay tuned folks.

Dang....those cells are looking pretty good. I'd pick some up, but I still don't even have a decent charger.

Thanks for the work in testing you're doing, Fishinfool!

Anytime Match.  It's the one and only thing I can contribute to BLF since I hardly know anything about flashlight electronics.  Maybe someday it will all sink in.  I guess I'm just a veeeeery slow learner.Frown

Im glad to see your batch works as good as they look. Will they receive the beer christening while at sea... like the outboard engine? Surprised

It never did cross my mind but any reason to go out fishing is a good reason.  We just have to wait for some decent weather.

It's a discount store here in the U.S. Closeout items, etc.

Any chance to get international shipping with that price? :/

I've sent out a few packs of these to members here.  Shipping is kind of a killer.  It's @ $16 to the U.K. and I want to say it was ~$6 to Canada.  I have no idea what it would be to Argentina.  But yea, we're kind of lucky to have biglots here.  I just picked up another charger/4pack plus another 8pack because they're working out so well.

Interesting discharge graphs, but which current draws are those lines showing? <-  do you understand my spanglish? Tongue out

Finally, after 40 hours or so (I've acually been testing these 8 cells since 2-23-11 which is 4 days of testing---man I need a lifeFrown), the final break-in numbers are here and they are right where I'm used to seeing sanyo eneloop numbers at.

Break-In @ 2500mah:

1.  2476 mah -- 1.43v

2.  2444 mah -- 1.42v

3.  2439 mah -- 1.42v

4.  2454 mah -- 1.43v

5.  2456 mah -- 1.42v

6.  2450 mah -- 1.43v

7.  2467 mah -- 1.43v

8.  2448 mah -- 1.42v

 

Now all I have left is to do all of these tests I've been doing to the last 4 XXeloops (cells 9-12) and then I'm done.......for now anyway.:bigsmile:

It would be interesting to see some run tiime tests to see how much longer the xx last over regular eneloops

You should make a runtime-test and bright measurement with one flashlight, first using normal Eneloops and then XX Eneloops. To compare if there is an increase in brightness (may be they have less internal resistance).

Very nice test, and very nice batteries. I just hope not to be drunk next to the computer or I will do the same Smile

@ ezeqdb - When I'm done with the last 4 cells I'll try doing some kind of runtime test.  I've never done one so I might need some advice as how to make the test fair and equal between the original eneloops (or 2nd gen eneloops=the colored ones) and these new xxeloops. Smile 

 

Here's some numbers on cells 9 - 12:

 

500ma discharge out of the package:


9.  1323 mah -- ICV = 1.43v

10.  1319 mah -- ICV = 1.43v

11.  1316 mah -- ICV = 1.43v

12.  1320 mah -- ICV = 1.43v

ICV = Impedance Check Voltage (after 500ma discharge)

Don't feel so bad - I have 64 AAs and 16 AAAs - and I give them all a break-in every twelve months, and keep a spreadsheet with records going back to when the cells were first purchased. (Feb '07 for the first 28) Embarassed

Anyway - quick question - what are the voltages you've got listed next to your break-in results?

Cheers

It's the C9000's final voltage after the final charge at the end of the break-in mode but it actually drops down to about 1.35v after an hour or two.

The 1000ma charge produced numbers very similar to cells 1-8 in post #15 above.  The numbers are very constant.  Not one stands out from the others which is very good and typical for Sanyo Eneloop batteries.  You gotta love 'em!

1000ma charge:

9.  2484 mah -- 1.45v

10.  2621 mah -- 1.45v

11.  2789 mah -- 1.44v

12.  2569 mah -- 1.45v

 

Now for a 100ma discharge.

i think fishinfool was hit by lightning as a baby ..

 

Two guys looking under the hood ..

one's looking at the 440 hemi

and one's looking at the interstate battery

 You have to understand How much work fishinfool has put into such a great database of batteries and how much time it takes to do all this ....

So when he hears there's a new  Eneloop Battery  available ...he starts thinking ..Oh goody A battery that will keep it's charge for a long time ..WHEW  that will save some time ..!!!

LOL   It's friggin' contagious isn't it?.  Laughing

Now I'm thinking about getting some of the Glitter Eneloops since they are the only ones I don't have yet. 

Damn it to hell!!  Here I go again!! Undecided
