Never buy chargers or batteries from eBay! 90% of the sellers there resell faked high quality imported goods from China.
There's a UK Based retailer in the UK that retails all parts through their website
http://www.chilternitparts.com/ and all spares sold are 100% genuine.
If you cannot find it. Try UK based businesses and they might be able to get it for you much cheaper!~
