Don’t open or puncture the batteries, install them backwards, or expose them to fire, high temperatures, or water. Don’t charge non-rechargeable AA batteries.

Apple wireless devices are designed to go to sleep to conserve battery power when you aren’t using them. If you won’t be using a wireless device for an extended period, turn it off. If you won't use the wireless device for more than three weeks, you should remove the batteries for long term storage.
