had this to say:

>Contacted Garmin about them, they said if one drains off some of the 
>voltage first they should work.  Did that, with some success.  Then, 
>as the batteries recovered, they didn't work.  Unit wouldn't 
>start.  That happened after I was off the paper maps bailing out to 
>Seiad Valley after hitting too much snow around Condrey Mt.  Needed 
>the GPS map to find my way to the Klamath River.
>
>And didn't have it.  It started right up after I found my way out and 
>got some alkaline batteries.
>
>Since lithium AA cells are nearly flat in voltage and current until 
>they die, it's an "iffy" proposition at best.  I learned rapidly to 
>not rely upon them in my Garmin 76 CSx.

I've not had the problem with my Garmin Extrex Legend.  I used lithium
batteries on my last backpacking trip.
