Bought a Sony PS3 controller at start of the year as my old one was being a bit dodgy....  
New one was all good until recently when it would start going flat after a few hours - throw it on charge and it appeared to charge fine, but again died after a few hours.
Now it wont charge at all. Plug it into the PS3 and the lights flash as if its charging, but soon as I remove the plug, it dies. 

Tried multiple USB cables in case it was the cable at fault, no change. Tried the other USB port - no change. Old controller still happily charges (and holds its charge).

Anyone had this happen ? 

I will contact The Warehouse where it was purchased, but think Ill be pushing **** up hill as I no longer have the receipt and suspect Sony will just pull the "goto retailer" line....

Does CGA apply even if youve lost the paperwork ? Its obviously an official Sony controller but is that enough to get anyone to do anything about it.....

I'm fed up with jumping out of planes/cars/boats at high speed in GTA5 on my old controller...and my mates more so, when Im the driver/pilot....
