Sony CycleEnergy Blue Made in China

[palomino77]

I went to Costco the other day and found Sony CycleEnergy Blue Made in China batteries, destined for European Market, on sale I bought two packs of 6, total 12, for just less than 30.00 USD. This for Mexico is a good deal. I got home and discharged 6 on C9000 at 200 mA, they where very consistent in capacity. I then checked impedance and put on break-in mode at 800 mA, and came up with the following results.


Discharge____________ Break-in_______Impedance

# 1 = 584 mAH_______ 777 mAH ______1.54 VDC
# 2 = 583 mAH_______ 762 mAH ______1.55 VDC
# 3 = 582 mAH_______ 758 mAH ______1.57 VDC
# 4 = 584 mAH_______ 752 mAH ______1.55 VDC
# 5 = 581 mAH_______ 770 mAH ______1.55 VDC
# 6 = 584 mAH_______ 758 mAH ______1.57 VDC

I looked for a manufacture date and could not find one.
Are these good numbers for these batteries? What would you recommend?
Why the inconsistent numbers on after Break-in capacity and Impedance?:thinking:

Color code: red = discharge, yellow = break-in

They also say 1000 charges

CycleEnergy used to be rebranded eneloops. My Japanese-made ones are hitting 79X mah after lots of use and dumb charging. The new ones just aren't up to the eneloop standard of quality, I guess.

Results look very good.

those are trusty, good cells, should be pretty much comparable to Eneloops :twothumbs:

CycleEnergy Blue Made in China "are know" to be rayovac hybrid. i have a bunch of them. CycleEnergy made in japan i only found sold with charger

you can find tests, discharge graph, and self discharge test on this forum

Update: I then discharged @ 100 mAh, let rest for about 4 hours, checked impedance, further discharged @ 100 mAh, checked impedance, put on refresh @ 400 mAh charge 200 mAh discharge, got the following results below:


Please give me your opinions.

Hello Palomino77,

They look good. Time to start using them...
