May I suggest that you report the Model Number and Serial Number to Mr. Carr. He is tracking all the problem units. -S-

Put me in the boat full of holes.
I brought along some CORKS. :unsure:

I would write more but I feel most of the prior
replies pretty much cover the issue and the users
experiences and scope of the problem.

I will be calling Magellan Monday to note the issue on my unit.

I also feel that one year is why to long to move this type of
issue to the high priority list.

ESPECAILLY WHEN YOU ONLY HAVE A 1 YR WARRANTY.
Also communication to the user needs to be better.
I'm a registered owner user and discussion board member
and there has been NO Communication about the possible or reality
of the issue.

I'm now a member of the walking DEAD
(Walking Dead Battery Club - that is)

I want all people to note this
WARRANTY DISCLAIMER: Magellan will, at its sole discretion and at no cost to the customer replace the defective GPS receiver with a reconditioned unit of the same model, as available. If the same model is not available, a comparable model GPS receiver will.

ONLY USED OR COMPARABLE MODEL - Great
RIDICULOUS

You are not alone about compass & map, I would make the same mistakes and have to wander a bit to find landmarks.

I got tired of replacing and throwing away lithium/alcaline batteries so I use rechargeable batteries now.
The weight penalty of half a dozen spares I can live with to give me the huge advantage of my 710.

And I also always have a map & compass with me.

Interestingly, I have had no battery bleed off problem. I have noticed that using lithiums, and the lithium settings, the battery meter falls alarmingly fast and then holds on yellow for a long time. If I use alkaline settings, it stays full and green for a long time. Psychologically I prefer the alkaline setting! I have become adjusted to carrying more batteries. yes they are heavy,but it's worth it. I can remember navigating with a map and compass all the time, and say what you want, but there were times when I would lose track of how long I hiked since last checking, or could not locate a prominant land mark, to orient myself, etc.,
GPS takes a lot of doubt out of navigating, and yes I still use my map and compass, but now it is much simpler and i can concentrate more on the scenery than on navigating.

I love my GPSr's especially this 610.

I have resorted to always removing batteries from my 610 until heading into the field.....sucks.....yes!

I did have a brand new set of alkaline batteries go from full to dead in about 5 days a couple of weeks ago. I put them in the GPS on sunday evening after a day of geocaching before uploading my geocaches. I then turned off the gps after just a couple of minutes. Then when I went to turn it on 5 days later it was completely dead. This is on an EX510 unit.

Try going into your settings and changing the setting to never automatically go into standby and see if the problem persists on your EX610.

I would agree that the 510 is void of the possibility of the problem relating to the altimeter/barometer component. The unit does not have the Barometric Altimeter Sensors.

What you may have accidentally accomplished is that the 510's will not have the drain problem.

Under these circumstances we would only be looking at the 610 and 710 displaying the drain problem if correct.

I have been doing more testing on my EX510. A couple weeks ago I had a new set of batteries drain in 4 days when powered off.

Now I have had a set in for just over a week. I only turned it on once when I first installed them, and again last night to check the battery level, still full, and I have taken the back off every evening to check the batteries voltage with a meter.

So far the voltage has been holding steady at 1.455 volts now for 6 days. No drain this week.

Very puzzling how I can have battery drain one week, and none the next. The only thing I changed in the settings is to never go to standby, and power off after 2 hours.

And in response to the sensor question others have posed. The EX510 doesn't have sensors, so that cann't be the culprit in my case.

The ‘Find Next’ is a fault in the firmware and should be fixed. This continual reliance on work a rounds is what gives a produce a bad name. It is impossible to educate every new purchaser on “oh if this doesn’t work do this” this is not the way forward if the company is concerned about its brand name.

The cause you found is reproducible so it should be a simple matter of finding and fixing the bug in the software.

The "Find Next" issue shouldn't take Magellan much to deal with as it was explained in an earlier post. As a matter of fact, I don't think there is anything to be done - just explain how it works.

I believe the power drain problem is a hardware defect in some units.
Otherwise my unit would have the same power drain that other units have.
If it was caused by the way that the sensors are designed to operate then all units, including mine, would have the same power drain problem.

If you have the barometer shut off the altimeter gets it's data from the gps signal instead of the barometer.

And I refuse to believe that anybody would design a battery powered device that can not be shut off.

I don't understand why there is any kind of battery drain at all, no matter how small, when the unit is not being powered by the batteries, as when powered by the vehicle power cord or usb cable.

There is also no reason I know of to need power supplied to the unit at all times, we can take the batteries out and the unit works fine when we put batteries back in it. Nothing has to be reset or recalibrated.

I repeat, if your unit has a serious battery bleed off problem while shut off I believe it is defective and should be replaced/repaired by Magellan.

And it should not be up to us to find out how many units are defective, what the problem is and then advise Magellan on how to fix it, that's Magellan's job!

WARNING WARNING SARCASM COMING NEXT! :woohoo:

Magellan should be used to this, years ago they had to recall every single one of the first batch of Explorist XL units they sold because of a defect they didn't notice. :blush:

Ok, just to let you know that I spent the day at an event with Jeff and Ken from Magellan and the power bleed, as well as the find next are on the top of there priority list.

....This makes me think that the sensors are always active and that the digit readout is only turned on and off.

I believe when the Power Off sequence is done the unit shuts off the processor, GPS receiver chip and the majority of the remaining hardware. It is certainly possible that some of the hardware (sensors, for example) may remain on, although I haven't experimented. I have noticed however, when viewing the Barometer graph (which is Always OFF in All profiles) that the graph tends to vary up and down with the current barometric trend (meaning it doesn't actually turn off when I tell it to), and it responds to Power Off and On and shows this on/off trend in the graph.

The 2nd part above I believe there is more than just the screen is turned off on a Power Off sequence, otherwise you would be in Suspend mode, which would essentially keep the screen off and keep the processors and sensors functioning.

Phil,

Theoretically you are probably correct. But maybe the only thing that the OFF switch does is turn off the digital display and not disengage the sensors. This would mean that the sensors are always powered.

What I notice in my 610 is that when I turn on the display I get an immediate response and no damping or oscillation effect in the readout.

This makes me think that the sensors are always active and that the digit readout is only turned on and off.

Another point is that when I looked at how these sensors operate I noticed that the electronics are joined. This also makes me think that if you turn off one sensor but use the other sensor the components have to stay on for both.

Again, I profess my technical ignorance of these matters. I am just speculating on possibilities.

If I am incorrect, Dave or some member of Magellan who monitor this forum can simple put my hypothesis to rest by saying that I am incorrect.

Also under my hypothesis this is not a software solvable problem and maybe that is why we have not seen in the latest firmware a "no solution" scenario.

What do the members think of this diagnosis?

The barometer does have an off option, it shouldn't be on at all unless you turn it on.

But the drain problem could be literally be anything, why would anything stay on or draw power after you turn the unit off?

You were most likely right about a manufacturer's lot with a bad component or production problem.

I noticed on the 610 disassembled pictures that the 610 has a large Altimeter/Barometer component.

I looked up the current consumption for similar devices in China and they are reporting =>10ma for the Altimeter/Barometer component.

I am not technical but is this something that could cause the Battery Bleed as they are never turned off unless you remove the batteries.

Just a hunch.

Yes and a couple of us also believe that the batteries bleed while in the Magellan vehicle power adaptor.

Well, that would appear to be the battery drain.
No matter what, there is a constant drain on the batteries.
At .5 milliamps it doesn't seem to kill my batteries in the two weeks I tested it for, so the units that loose their batteries in two weeks or less must have a higher current draw for some reason.

Perhaps, at least until we hear from Magellan about it, taking the batteries out over night would be the best course of action.

I know, I know, it's a pain in the *** but it's better than dead batteries every other time you grab the unit, isn't it?
And we all carry spares anyway, keep them with the spares.

I hooked up the multimeter test while connected and powered by usb and I get about .5 mill amps draw just like when powered off. That is really strange. Because I can remove the batteries when powered by USB and the unit stays on. I would think that there should be zero draw when connected to USB power.
