Caddie Battery is the first and only CR2 rangefinder battery designed specifically for golf with a mission to give back to golf charities and improve the on-course experience for golfers. A portion of each sale will be donated to the US Disabled Golf Association and Youth on Course. Caddie Battery fits perfectly into pro-shops. My clients are getting a high-quality battery that is cheaper than most anything else on the market. I'm on a mission to make Caddie Battery Golf's Battery.
