This is the next increase in battery capacity, from 3400mAh to 3600mAh, this is not a huge increase.
With my test conditions (Discharge to 2.8 volt), I do not get 200mAh more capacity, more like 100mAh.
The cell used can be discharged down to 2.5 volt, in my test I only discharges to 2.8 volt, i.e. I do not measure the full capacity. But then, not all lights will be able to use the full capacity.

Orbtronic uses a very nice packing for this battery.

Conclusion

When comparing this battery to the 3400mAh cell, the new battery has slight higher voltage and slightly higher capacity, this is not a revolution in any way, just a small improvement.
Being based on a Panasonic cell the battery is, of course, a very good battery.
