    Many thanks for your comments regarding the Garmin rechargeable battery pack, they frankly are shocking.

    It is a product that Garmin have not updated for nearly 10 years now and battery technology has improved lots in that time.

    I personally would get a refund from the retailer you bought them from (happy to do that ourselves if bought from us) and get some good quality rechargeable AA batteries.

    I hope this helps.

    Hi, i’m in almost the same position as Torben except i have the 64sx. i have power saving on, screen brightness on low or mid, screen timeout to 30s, GPS only (not GLONASS), bluetooth off, track interval set to lowest, map detail set to low, 50k topo maps active but no others.
    Such a shame because the unit is amazing to use, but i’m going to have to get rid of it if i’m worrying about it dropping dead mid-hike.

    I have the same issues as Torben (March 31, 2021), battery life is short with the Garmin rechargeable battery pack and even worse with AA batteries. When using it for a multi day trip you have to bring a lot of extra batteries.

    Hi GPS training people.
    I’m using a brand new gpsmap 64st with the Garmin rechargeable battery pack.
    Ive just returned from a 2 hour walk, using only the trip computer. That is no light on the screen from leaving home till coming home.
    Only 20% left on the battery 🥲🥲
    What can I do to the 8-10 hours that you talk about?
