If a cell was working satisfactorily, but ceases to function before the
warranty period expires, the customer will receive credit toward the purchase
of a new cell.
If you have a warranty claim, you must return the cell in question to the
factory for evaluation. If it is determined that failure is due to faulty work-
manship or material, the cell will be replaced at no cost to you.
Note: Evidence of damage due to tampering or mishandling will
render the cell warranty null and void.
