Humidity
Optimal humidity is 35% - 45%. If your home's humidity can be maintained at that level (most cannot), you don't really need to humidify your guitar. If not, use a device. If you want to know the humidity, go to The Source (formerly Radio Shack) and buy a small electronic hydrometer.
You can't damage the guitar's electronics or battery by humidifying.
