What SudsMaster said.
I recently bought a cheap Chinese replacement for a Ryobi cordless tool battery charger, on Ebay Australia. It was a fraction of the price of a genuine one.
When it arrived, it wouldn't charge my batteries, it showed a red fault light. If I lifted the battery slightly, it would charge. It seemed one of the contacts was dodgy. I contacted the seller, told them the issue. I said I was not a professional technician but had years of experience with electronics. I asked if they were happy for me to open the charger and see if there was a poor solder joint or similar that would cause the problem. They were very nice, said they were happy for me to take a look and if there was an issue that I could fix, they would compensate me, otherwise they were happy to return/replace.
When I had a closer look, I noticed one of the springy steel contacts was sitting different to the other two - it was sticking out more at the top. I just pressed it back in with my finger and it snapped neatly into place. It was a simple assembly error, the spring steel contact was crooked when the two halves of the casing were put together, so the top end was outside instead of inside the casing.
I contacted the vendor, told them what I had done, that it was now working perfectly, I was happy with it, and that I don't need any compensation, I was happy with the price paid. They sent a reply saying thanks and that I was "a very good buyer."
Everybody happy.
I have straightened many of those element terminals, new ones and old ones. They just bend straight, no drama. The only ones that have ever broken off for me were old ones that had rusted. But to be on the safe side, you might contact the vendor. Then you have covered your a$$ in the unlikely event it snaps off.
