E-X1 Battery cost

My local camera shop has Fujifilm E-X1 batteries for £59.00 but I have just found that KingBattery.co.uk are selling what I assume to be the same for £11.56 !

The picture and details of the battery shown appear to be identical,  the specification & NP-W126 number is the same. The only difference is some Japanese/Chinese writing on the one supplied with my camera.

The difference in price is extraordinary and makes me hesitate in buying the item. Has anyone used this firm or bought a similar battery.
