The first battery I received did not work. The voltage was only 8 volts, while the old battery I was removing had 9.5 volts. The new battery did not have enough power to put out a signal on the ELT. It was removed and the old battery put back in. This is the first time in 20 batteries that I have had a problem with the battery. A new battery was sent and worked fine and the bad battery was returned. I noticed the batteries in the new units are Chinese Duracell batteries rather than U.S. batteries.
