Knock off batteries from China have zero warranty 

 

You and those around you are very very lucky they have not caused any damage, destruction, injury or death

 

What you can do is dispose both of them appropriately and not take such huge risks buying highly dangerous goods from randoms in China

 

It is not the same as buying genuine items made in China

 

It is buying who knows what that was knocked up in a ‘backyard’ warehouse using the cheapest components possible
