For reliable performance, use AAA Energizer® Ultimate Lithium 8x batteries (L92) or NiMH rechargeable batteries. The power light will blink red when batteries are low. Colder conditions and extreme heat can impact battery life. Always carry an extra set of batteries with you. Non-lithium batteries will work with SPOT but are not recommended for optimal performance.
Test your SPOT device before each trip by sending a Check In message to yourself. Using non-recommended battery types may degrade the performance of your SPOT’s message transmission.
