Low self discharge (LSD), can stay charged for 1 year
Maximum temperature raise at different discharge currents: 1A:+0,9°C, 2A:+2,9°C, 3A:+5,2°C, 5A:+10,6°C, 7A:+15,9°C, 10A:+22,5°C
This is the premium AA cells from Duracell and their chargers need much longer than specified time to charge them, due to the higher capacity.
This is very nice discharge cuurves the they tracks nicely and are above 1V even at 10A discharge.
These batteries might be good when new, but mine didn’t last very long. All four of mine now have over 1000 mili ohms of internal resistance (charger only goes up to 999). One battery caused a buzz in a charger……….ie: oscillation of the control electronics. 3 of them I could not get out of the low mode on a flashlight. They have very few cycles on them.
I have never had a regular Eneloop go bad. The 8 Gen-1 cells that I bought long ago (2008?) that are in my metal detector still work fine. So as you can imagine, I will never by buying any more Duracell 2400mAh Ion Cores.
