Maximum temperature raise at different discharge currents: 1A:+2,2°C, 2A:+5,4°C, 3A:+8,4°C, 5A:+12,3°C
In my test Sofirn AAA batteries this is the lowest capacity cells (The other are 1100mAh and 1800mAh), can this battery live up to its specifications?

The discharge curves looks fine with a very good match between the cells and capacity is close to 900mAh.

[size=+3]Conclusion[/size]

These cells has about the same capacity as the 1100mAh & 1800mAh and that is about 900mAh.
The discharge curves looks fine.

900 mah aa nimh seems pretty good to me if it really is lsd. Where are you getting 1100 and 1800 mah? Has the company, like others, previously put stupidly high capacities on aaa batteries?

I would not expect any LSD ability in these batteries. The review contains link to the two other Sofirn capacities and you can get them on ebay.

OH ok, so they are just finally telling the truth about capacity, though lsd aspect is iffy.
