Query: Battery dead in 5 months

Bought these for our sports team on December 6. Five months later the batteries are dead even though it is advertised with a 1.5 year battery life. Looks like they were manufactured in 2009. There is no tab to pull out to start the battery running the watch so it is running before you receive it. They take an LR43 Maxell battery and you have to remove 5 tiny screws to change the battery. I wouldn't buy it again. It does work properly, though, until it dies.
