What is the general estimate of battery life for Gen4?

To obtain reliable performance use only AAA Energizer Ultimate Lithium 8x batteries (L91). For optimal performance, please try and utilize SPOT in locations with a clear view of the sky with the logo side up.

Extreme heat/cold and trying to send messages indoors or under extreme canopies can drain battery life. If the On/Off indicator light blinks red this is a warning your battery is about to die. Always carry extra batteries with you. Test your SPOT device before each trip by sending a Check-in/OK message.

Proper battery selection is critical for the best performance.
