Self-Discharge: approx. 85% capacity after 1 years
These eneloop has higher capacity and shorter charge retention time than the white version
Maximum temperature raise at different discharge currents: 1A:+1,3°C, 2A:+3,7°C, 3A:+6,5°C, 5A:+13,0°C, 7A:+19,5°C, 10A:+23,9°C,
There is some variation between the cells.
Note: Small capacity differences are much less a problem for NiMH, than for LiIon.
Conclusion
These batteries can maintain power for a long time and can also deliver a high current.
I wonder why they only have a 1 year rating, compared to the 1900mAh eneloops 5 year rating, does these batteries have a shorter lifetime?
HKJ, thanks for great reviews as usual.
I am wondering do you keep record of nominal voltage after charging, for example one day after charge, one week after charge, etc.
I raise this because I found that some brand of LSD has lower voltage after fully charge. Eneloop claim that their voltage is higher than other LSD.
I have come to believe that claim means higher voltage under load because of their lower internal resistance, in my experience the voltage is the same, i have a device that says batteries are dead at 90% an they react to eneloop the same as other NiMH batteries
I was thinking is Eneloop more suitable than other LSD for those low load and a lot resting application like TV remote control, wall clock, etc if they claim they have higher voltage. If under open circuit condition, is all LSD going to have almost same voltage after resting for a few days after charging?
I have noticed that 1.37V means resting full for eneloop after a week or so, others are not lsd cells and fall quickly
i’m referring to the white cells, second generation, not the ones tested in this thread, i don’t have any of them
So the chart says the cell is a Panasonic. Do Panasonic make all the Eneloop cells for Sanyo, or just these?
I see they are 1.5g heavier than the 2050 mAh Eneloops, but if I do the math correctly it looks like they may yield roughly 10% more efficient capacity for the weight ratio.
Panasonic has bought Sanyo…but still products from Sanyo will exist because it has a good name…the newest eneloop batteries have a big Panasonic letters printed over the whole battery and only a smaller eneloop written on them.
I would agree the energy density of the black is about 14 percent better.
Black energy density. 2.968÷29.9=0.099mWh/g
White energy density. 2.254÷25.9=0.087mWh/g
0.099/0.087=1.14
Just a quick calculation based on the 1A discharge from HKJ, with ignoring the different size measurement…
