Battery voltage for this new alkaline button battery should be 1.5 volts. Closed circuit voltage test, batteries under load ranged from .7 volts to 1.1 volts. Compare with Sunbeam batteries from the Dollar store (5 pack) three years past the 2014 expiration date tested 1.5 volts out of the pack under closed circuit load test.
The battery contact surfaces were easily scratched. The batteries were thinner than the replacements by about two sheets of post-it notes (0.0086 inches).
Batteries were used for flashers which operated at voltages as low as .5 volts so I chose not to return them.
