On the last three hikes, my 60c seems to have powered off by itself. I first
suspected that in my fiddling with the mount, I turned the GPS off accidentally;
but the mount is on my packstrap by my ear, and I haven't heard the distinctive
tone sequence that signals a power-off. The power-downs have come when the
batteries were near full charge, and up to two hours into a hike.
Also, today I noticed that I had to open the battery case and fiddle with the
batteries to get the unit to power up. These are 2000 mAh Gold Peak NiMH that I
have used in my other GPS with no problems. I've had some odd experiences with
the GPS power -- the map-screen meter will initially read only 25% for fully
charged batteries, then will read full charge by the end of the hike. Opening
up the case and just touching the batteries once had the effect of sending the
reading from 25% to 75%.
I guess I suspect poor contacts with the rechargeable batteries. The metal
clips in the battery case don't seem to hold the batteries very snugly.
I'd agree with that assessment. I have a set of four NiMH batteries that
came with an electronic device, and they seem to be just a hair shorter
than other AA batteries. The result is they don't make good contact in
some devices with weak battery clips.

I'm just now running into the same problem... It's definitely the weak battery
springs... Flexing them out helps a "little"...

Yes, it's surprising how many different models have had this problem of
loose battery contacts causing unintended shut-downs. The
45/38/12/II/III/V series all shared a similar battery compartment
with two tubes each with a pair of cells and Garmin's solution was the
extra set of springs upon request. The eMap also had weak contacts in
a different 2-cell design and many users added foam or pen-refill springs
to fix their units. Etrex models have had slight changes made to the
battery contacts over the production cycle with some having a spring at the
positive terminal end that led to a few melt-downs from shorted NiMH cells
and others again suffering from cells that were too loose. Now the 60c/s
models also appear to have poor battery contact.
Odd that this should be such a recurring problem across a wide range of
battery compartment designs.
Oh no - I've had different Garmins over the last six years with this
kind of problem. It appears that this will persist as long as the
manufacturer is called Garmin.

But a power monitor circuit (sometimes combined with
watchdogs) could shut it down if it felt the batteries were
on the verge of dying.

Various firmware releases on my GPS 12, III+, and eMap had no impact on the
problem. Putting extra springs or foam in the battery compartments to keep
the cells from losing contact immediately cured it in all the units.
Even though there are many references to this issue on the internet,
and Garmin was even once giving out retrofit springs, a call to
Garmin's support department proved them to be either clueless or lying
about knowing that a problem exists.
In any case, I solved the problem completely by cutting a couple of
small pieces of foam to go between the batteries and the compartment
door- the idea is to immobilize the batteries in the compartment. If I
ever get around to it, I intend to try a little self adhesive weather
stripping stuck to the compartment door.
This is apparently more of a problem with rechargable batteries than
with alkalines because the rechargables are heavier and tend to move
around more in response to vibrations or bumps.
Just my 2 cents worth.

Same problem here, hapens 2 times ...the screen go's blank and the 60C
powers down without any reason.
I also think it's a bug. My 60C is about one week.

My Garmin Etrex Vista--as with most other Garmin units that I have tried--has
much thinner and "tinnier" contacts than does my MAP 330. I notice that, in
the Vista, alkaline batteries fit more tightly than the NiMH rechargeables
I've been using, which have been Ray-O-Vac.
Has anyone else noticed this? I only noticed it recently, which makes me
wonder what type of quality control some battery companies have with regard
to physical battery size, esepcially the "AA" category.
Warm regards from,

When I used NiMH AA in my Kodak digital camera, they would often make poor
contact (as in no, or erratic power when the unit was turned on). I "solved"
the problem by bending out the leaf springs. My brother claimed he was finding
the same thing for his digital camera. That was a while back, and the NiMH were
Nexcells and Eveready. Now I use Gold Peak, and that camera is long gone.
I'm hesitant to do much bending of the 60c springs, because I figure I'm in a
world of hurt if a spring breaks. However, I figured the NiMH contacts were
probably getting oxidized (they have been used at least 50 times), so I did the
perhaps futile trick of cleaning the contacts with a pencil eraser, and also put
foam in the back of the battery case.
All this makes me appreciate my awkward Magellan STP battery cartridge, with its
coil springs.

Cleaning the contacts and batterie terminals with alcohol resolved the
shut-down problem and resulted in a two bar increase in battery
condition as indicated by the 60CS's "fuel gage".
later, I put some foam cut from a mouse pad under each contact to
hopefully further reduce the chances of a shut-down. Before adding
the foam, there was a noticeable ringing and other sounds indicative
if loose objects within the unit when the 60SC was tapped.
Garmin certainly could improve their battery contact design. My 12XL,
Vista, and III+ all required simple modifications to the contacts and
careful attention to the cleanliness of both the unit's contacts and
the battery terminals.
Decades of experience has proven to me that this is a problem with
most battery powered devices. I suspect it shows up more often with
GPS units due to the vibration we subject them to.

I haven't had another spontaneous shutdown
(knock on Formica), after doing two things:
1) putting a piece of polyethylene (closed cell) foam
at the back of the battery pack, and
2) cleaning off the contacts of all my NiMH batteries with a
pencil eraser! I'd recharged those batteries at least 25 times,
and they were getting a noticeable fuzziness at the contact points.
