Just in case you can’t make your millions off the greens like Tiger Woods and his caddy, at least you can lug around a battery caddy, holding all your precious rechargeable batteries in one place so you won’t lose track of them. I find this pretty much a pointless exercise, but this gizmo would definitely come in handy for the less organized. Prices range between $4.95 and $13.95, depending on the size. I suppose this would be handy back in the monochrome Gameboy’s heydays.
