Hmmm, it does get it's power from the usb port.

A while ago I pulled the batteries while 'connected' to the pc to find out where it got it's power while connected.
The unit stayed on and connected.

That tells us something about the battery drain, I'm not sure what though.

Eh...I've noticed mine bleeds off also when I leave it plugged into my PC that I NEVER turn off. Thought it would get it's power from the USB ports and not run them down seeing as how I do not let my pc go into any hybernation or reduced power modes other than a screen saver. I also have my usb ports remain active full time (aka.....don't use power save feature on it either)

Oh well...Just another part of pre-adventure prepping for me. It is kinda annonying in a way tho...

I am just a member of this board and an owner of several Magellan units.
I have no inside information or contacts at Magellan or MiTAC.

I am not trying to be a leader or a "chief" of anything but was just suggesting that it might be a good idea for anyone that has a defective unit to report the problem directly to Magellan.

Mr. Carr has been great in contacting, coordinating and keeping us on this board informed on what he has learned about many issues.

I never suggested that anyone not send serial numbers of defective units to Mr. Carr

But if Magellan also gets complaints and repair requests through their own customer relations/support departments they may pay more attention to this issue.

Yes, my 710 does not have this problem but I have been trying to find a possible cause and solution to help the people that do have a defective unit.

So, with all due respect, Mr. Carr informed the research department at Magellan about this issue months ago.
The people with units that have this problem that still have a warranty on them might want to try contacting Magellan about the problem before the warranty runs out.

MiTAC's quality control department needs to be informed about this issue, for whatever reason Magellan apparently has not told them about this issue.

I can't complain to MiTAC or Magellan about a problem somebody else has.

To make myself clear, send the serial numbers to David but it also might be a good idea to contact Magellan about your defective unit.

Again may I address the obvious.

I have no idea who pchild1 is. I do know that Mr. Carr was pursing this problem.

I do not understand why he cannot continue to keep leadership of this problem as he has in the past.

I will send my serial number to Mr. Carr and assume that unless he gives up his lead we do not create too many "chiefs".

Lastly, the 710 units also have the Battery bleed problem and this has also been reported by many members.

So, with due respect, just because your 710 does not have this problem simply proves my suggestion.

Namely, that we obtain a list of the serial numbers with the problem and see if they point to a production or component problem.

MiTAC has an excellent Quality Control program. I rather believe that something is amiss in the components used in the printed circuit boards.

David, I appreciate all you have done to help resolve this issue but Magellan apparently has not gathered enough data on this issue. :blink:

This thread was started almost a year ago in response to an earlier thread.
Magellan's research team has known about the problem for almost a year now and no communications about a possible cause, solution or even that they acknowledge the problem exists has been forthcoming. 🙁

My 710 does not have this problem so I have no real issue to complain about to Magellan.

But, if every owner of a unit that does have a battery bleed-off problem while shut down sends a complaint and request for repair, replacement or refund to Magellan, I assume they would have to notice that they have a real problem with many of their units.

Who knows, they may send new units out that do not have the problem and everyone will be happy. 🙂

Of course a refund may be out of the question with the one year warranty being expired. :dry:

Forgive me for suggesting the obvious. If some people have a battery bleed problem and others do not. Then why does Mr. Carr or someone make a list of the serial numbers of the units with a bleed and the ones without.

It could be a problem related to a production lot and not the entire production. :ohmy:

Comparing an older map330 to a new 510/610/710 is a prime example of comparing apples & oranges.

This problem has been reported for quite some time now.
As I suggested a long time ago on this thread if your unit is killing batteries while shut down there is something wrong with it, send it back to Magellan and demand a new one!
Not a repaired/refurbished unit!

If Magellan won't or can't fix this problem get your money back and buy a Garmin or DeLorme.

And be very loud in your complaints about a basic problem that has not been addressed by Magellan in any noticeable way!

Strangely I am getting very similar readings as you, and I had a set of alkalines go dead in 4 days. I did notic one thing. When I put in new batteries and powered up. It started indexing the databases like when not shut down properly.

I checked an older map330 gps I have and it only draws .1 milliampere when turned off

Those lithium batteries just happened to be in the unit at the time, they were partially used up.
I just tried the test again with half dead Eneloop XX rechargeables - .39 milliamps.
Then with fully charged Eneloop XX rechargeables - .83 milliamps.
Even at 1 milliamp it would take 2400 hours to drain them.
That's more than 3 months!

I'll remind you that I do not have a battery drain problem with my 710.

I tried holding the power button in to power the unit up and got 7+ milliamps also.
My unit also did not power up.
Apparently the impedance of the milliampmeter prevents the unit from powering up.

I no longer have access to good test equipment and I'm going to need an induction DC milliampmeter to do a more thorough test. The meter I used on the railroad before retiring costs over $1000, I won't be getting one soon!

I suspect the 7 milliamps was the unit trying unsuccessfully to power up and not the "power drain" issue we are looking for.

BTW, I don't see how having an SD card installed would effect the battery drain problem.
And does anyone use a 610/710 without an SD card? If so, WHY?

I noticed in the pictures that you were using Energizer lithium batteries. Tried the same test with them and got .58 milliamps on my EX510, but with alkaline batteries I get .80 milliamps on the same volt meter.

I repeated the same test on my EX510, but I got .72 instead of .47 milliamps which is not a huge difference. But then I tried something that really changes things. I pressed the power button while the meter was connected. The unit never powered on, but the current jumped to 7.12milliamps and stayed there until I disconnected the meter and reconnected it. Part of your test was to break the battery contact by putting the paper strip between the battery and ther terminal. This somehow resets the drain problem. So I bet if anyone took their battery out after powering down the unit momentarily it would break the drain problem until they used it again. I will test this over the next few days.

Just a non-scientific poll:

Is everyone that is having the bleed off problem using an SD memory card?

I havn't tried removing mine to see if the problem persists or not?

I think I just experienced the battery bleed off. I have only had my 510 for a few weeks and have been using it alot, but Last Sunday I finished geocaching and had to put in a new set of alkaline batteries at the end of the day so I could upload my geocaches to vantage point. When I was done I turned off the unit. I did not turn on the unit again for 4 days. When I tried turning it on the batteries were dead, it just flashed and went off. Granted these are cheap store alkaline batteries, but they lasted me at least 6 to 7 hours when geocaching having the unit on.

Hi, I'm new to the board, Geocacher from Cologne, Germany.

Just wanted to add that my 710 has an extremely nasty problem with bleeding-off batteries. In the first weeks, I thought it just takes that much when in Standby Mode. I've read some forum hints to switch off sensors not needed (which I did at least with the barometric sensor).

When the problem kept going, I thought for I while that I have forgotten to switch it off. After a while, it dragged my attention and I tested it in detail:

Regardless, if I use Sanyo XX, Eneloops or Panasonic (all fresh and fully charged. With the 710 definitely switched off (instead of Stand-by), latest after TWO days the batteries are empty. Completely. :huh:

Since discovering that, I always remove the batteries after use, but I must say this a little bit disappointing for a device of more than 530 Euros.

Magellan, please take care of it ASAP.

Tom

I can say my x710 DOES have this problem, a set of fresh batteries will die in a week or 2 if left in the unit... cost me a small fortune till I started to remember to take them out when I turn if off.

eXplorist 310 has been living for months on one set of batteries GoalZero 2100. I've used it several times at 5 - 10 minutes.
In the lid there are no magnets. Judging from the photos under the cover no contact.
Maybe it's a problem specific instance of the device.
