They just need something tangible to show the manufacturer so they can get reimbursed for it. If they just say "the client says it shorts" the supplier will ask them if the clients batteries are at fault.

returning it to them is the only way they would find a problem. If it where a regulated mod it's easy to show the fault. I could find out whats causing the short but i ain't gonna damage my batteries doing so. Might cost more to replace the batteries than the mod cost
