Batteries - change ‘em and charge ‘em

Batteries are a crucial item for climbers, and it’s easy to overlook them when packing in a hurry for a trip.  Be sure to change out or fully charge all needed batteries well before you leave for your adventure.  For many climbers, this will mean 4 items - headlamp, GPS, digital camera, and cell phone.

Tip - try to buy electronics that take the same size battery, such as AAA.  This lets you swap batteries between, say, your GPS and headlamp if needed.

See this previous tip for a discussion of the next generation rechargeable batteries, which hold a charge much longer then before.
