This is the latest cells from Panasonic with the highest capacity.
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.

EnerPower is mostly focused on Europe, that means you can find them in European shops, especially in lampentroll, Enerpower does also have a ebay shop.

Generally price inside Europe is higher than US and Chine price, i.e you can probably find the 3400mAh batteries cheaper, but not necessary in better quality.
