Spotlight cam batteries draining so quickly now

I've had 5 spotlight cams with batteries for about 10 months. They've been working great until about 2-3 weeks ago, when the batteries are now draining incredibly quickly. I'm not having any more events/live views than I've had in the past 10 months, but all of a sudden now all of my batteries are now draining completely within a few days to a week. I fully charge them before inserting. It's not currently cold where I live and my settings are the recommended ones. I am at a loss.
