Okay so yesterday I emailed the eBay seller about the item and received a full refund today.
Here is the response I got.
"Hi, Thank you I bought a whole lot from a RELIABLE source, and I never bought anything fake from them. I used this batteries myself but what I found out that they have be charged with a HIGH CAPACITY CHARGER,I tried with a regular charger that i bought, and only charged for only 30 to 40 minutes so I looked into the charger and i found out that is only output 1600 am and those batteries they need to be charge with a charger of 4600 to 5000 am I have no problem refunding u the money and u can keep the batteries if it haPPENS that u get the right charger you will be more then happy with those batteris. Thank you in advance and again sorry for the inconvenience."
Dunno if this is accurate information or not, probably not, but I got a full refund without even sending back the batteries so it's cool with me either way I suppose.
