Be sure to do a little research (owner's manual or home page) to make sure that the device can use lithium batteries. Garmin GPSMAP GPS's and several headlamp/flashlight manufacturers (Streamlight, Petzl) specifically state that lithium batteries should not be used in their products.

On the other hand, I use lithium AA's in my small Nikon point-and-shoot camera, and will never mess with alkalines for that use again. Sooo much longer usage time between battery changes.

I agree that alkaline battery leakage is a major problem. I make sure to take batteries out of flashlights and other devices that are not in immediate use. I just store the batteries near them. I've lost several flashlights and at least one radio (FRS) to battery leakage.
