RE: cheap chinese batteries
MaxAmps make the best batteries in the business. You really do get what you paid for. Some of the extra money you spend on MaxAmps goes to assembly and manufacturing costs which are higher if you are doing it in America and the rest is for the grade A cells they use. I can understand not everyone has the money to spend on them but if you think the extra money spent doesn't get you an all round better battery you're wrong.
As far as I am concerned any tests that I have heard of done on MaxAmps batteries in the public arena were not done on a brand new battery and weren't tested at high enough loads to properly test the C ratings so they can't be taken seriously.
