SPOT Gen4 Assistance
Can I use other batteries in an emergency with my SPOT Gen4?
SPOT recommends that you use either Energizer™ Ultimate 8x AAA Lithium or Energizer™ NiMH Rechargeable Batteries to achieve reliable performance.
Other AAA batteries will work with SPOT but are not recommended for optimal performance. Using non-recommended battery types may degrade the performance of your SPOT’s message transmission.
Always carry extra batteries with you.
