My new Sanyo AA XXeloops just arrived today from CameraMate2010 (Ebay) and they are so beautiful I feel like a kid getting a new toy. :bigsmile: I ordered them on Feb. 16, they shipped on Feb 17 and arrived today. That's only 6 days which is pretty fast. Date code is 10-12 TQ which of course is Oct. 2012 so these are batteries from the future. Just joking.....they're from Dec. 2010.
I checked them out of the package with my ZTS MBT-1 battery tester and they were all at 100% which is no surprise since they are brand new. I just started discharging the first 8 @ 500ma on my 2 - C9000's and will post the results as soon as I get them.
After discharging, I will do a quick 1000ma charge just to get some initial numbers. Then I will discharge them again and do a break-in which is what I do with all of my new nimh rechargeables.
4 of them will be put aside so I can do my own self-discharge test which I am currently doing with 6 other sets of batteries--some of which have been on my self-discharge test since April 2010.
It wasn't my fault......my alter-ego Batteryfool took over and bought them.
I didn't even know it happened until I came out of the trance and noticed the new paypal charges. Or maybe it was during a drunken stupor which happens quite a bit.
Batteryfool - LMAO. That's cool - I just wanted to verify that was "the deal." I know some people will *cough*sellthemontheside*cough* for less. Excuse me, started coughing while I was typing.
What about the voltage? is it really a bit higher than 1.2?
And the internal resistance? Is it lower? will it give more current in the same flashlight (side by side with normal eneloops)? I know, I will wait you discharge and charge them a couple of times with those C9000 -you have two!
I finished a 1000ma charge and the numbers are a lot higher than I expected especially from Sanyo eneloop products. Here are the numbers:
1000ma charge:
1. 2476 mah -- 1.44v
2. 2701 mah -- 1.44v
3. 2770 mah -- 1.44v
4. 2738 mah -- 1.44v
5. 2649 mah -- 1.43v
6. 2730 mah -- 1.43v
7. 2818 mah -- 1.43v
8. 2585 mah -- 1.44v
The numbers on cells 2-7 are just too high imo. I have 104 other eneloops (gen.1, gen.2, duraloop) and I've never seen their numbers go this high. So now I'm doing another discharge and after will do a break-in on all of them. I'll post these new numbers as soon as I get them.
Hmmm especially the voltage around 1.4V is impressive! I didn't think NiMH chemistry could produce much over 1.2V. How much do your regular white label Eneloops produce with that same charger/meter?
The 1.44v is the voltage that is shown on the C9000 right after a fresh charge, refresh/analize, or break-in but it usually settles down to an average of 1.35v give or take a couple hundredths of a volt.
Don't you have a C9000 and a bunch of eneloops Mr. Admin?
I know you're into AA's so I assumed you have a ton of eneloops and at least 1 - C9000.
Congrats on those bad-assed looking XX power capsules. If you like them and want them, then thats all that matters. Being a Sanyo product, Im sure them will perform as others have already tested on their C9000's. They sure did soak up a lot of current during the 1000 ma charge. Looking forward to your next discharge test.
Thanks Flash. I really, really do like them because they are the coolest looking batteries I have. They will also replace my powerex 2700's in my dslr flash unit and will hopefully give me quicker recycling times.
