I went through 2 digital cameras with rechargeable batteries, the batteries lasted about six months and would not charge anymore.
Then I got a Canon PowerShot A430 that uses AA batteries, I put a pair of Energizer lithium AA batteries in it and have taken well over 2,000 photos so far without changing the batteries.
I have it set for maximum resolution and size.
The camera stays in my pack/pocket, take it out and take a picture!

The bottom line is get good batteries!

If the Explorist batteries die while shut off after a week, take the batteries out of the Explorist.
Yes, it's a bit of a pain but when you know they will die in a week why leave them in it?

My 710 does not have that problem of the batteries being used up while shut off.
I would suggest there is something wrong with your 610 and get Magellan to replace it.

David,

I must also report that the battery drain problem in the X10 units is real. I only use rechargeable batteries and do not have a problem if I put them in my Triton units.

For example, I can put the same newly charged 2950 mAH batteries in my Triton 500 and still have at least a 3/4 charge in one month of storage.

I cannot do this in my 610 unit. To me the problem is real!

My only solution is to remove the batteries and use when needed.

Mary

Over the past 10 years, I threw a few dozen accumulators. All of them did not die from loss of capacity. They were discharged in 1 day.
In addition, they have increased the internal resistance. The voltmeter shows the normal voltage. Energizer Battery Tester measures the voltage under load of 10 mA and shows an hour later 10% of capacity.
Just yesterday, decided to give old batteries for toy car my daughter. As a result, 10 units GP 2500 were not included in the toy, and went into the dustbin. In the morning LaCrosse BC-700 showed the capacity of 2200 mAh, and in the evening, they were completely empty.
All the usual accumulators died. In survived Ansmann MaxE, GP ReCyko, Sanyo Eneloop.

I never got any new rechargeables, and I'll wait to get a good smart charger first.

The issue at hand is still the Batteries going dead in the unit. And again, I put 2 new alkalines in it last week Friday, turned it on 2 or three times, then turned it off immediately. After one week, I took it yesterday, only to not even turn on for me. I got the Magellan screen for all of about 3 seconds and then blah. I'm NOT happy. I would like to see Magellan look into making a modified battery cover, that would house or accept a Li-Ion battery pack that's already commercially available, and have a charge wire stick out the back, totally independant of the unit's usb port. Whether it's waterproof or not, I don't care, they still sell silicone, I'll deal with the water. I DO want a unit I can grab and run, and not have to f__k around getting 4 new AA alkalines out of the cupboard for a 1 hour hike and a photo or 2. This is simply NOT ACCEPTABLE anymore. Whether you use the oem cover with AA's, or a new cover with a recharge pack inside, could be your choice, but I'm so fed up now that I Want that choice available. I purposely bought a digital camera before Christmas that came with a rechargeable battery, for EXACTLY that reason. Plug it into the wall, and when you want it, you grab it. Period.

Quite true... Freshly charged NIMH Energizer 2300mA batteries : 1.43v
Same batteries 24 hours - 1 day later : 1.36v on the shelf and 1.35v in the unit.

After day 4 I've got 1.32v on the shelf, and 1.29 v in the unit. If standing voltage goes down at that rate, I'd be curious to see in a couple of weeks. The thing probably won't even turn on ! I have 2 of these batteries in my digital camera, as of about 3 weeks ago, took 2 pics today and they died - the unit shut off !

Next week I'm picking up a 4-pack of the P-C ones and I'll let y'all know how they are.

Very interesting. I did a quick search regarding PC batteries being the same as Enloop and you may be onto something. Here is a good article that tested most of the slow discharging batteries. PC batteries (Presidents Choice) are made in Japan and so are the Sanyo Enloop.

http://www.stefanv.com/electro.....harge.html

Looks like the PC batteries are pretty good (I think they are only available in Canada)and they are cheaper than the enloops.

I read on one of the Eneloop facebook pages that someone suspected that President's Choice NIMH are actually re-labelled Eneloops. I'd almost tend to believe that, as PC usually copies only very good quality products anyway.

Any thoughts ?

Nope, there's no charging capabilities on these units.
Just as well, why complicate them with something that's not very useful?
When the batteries die I'm not anywhere near a power source, so I would have to carry spares anyway!

Somewhere I thought I read the 710 would charge rechargeable batteries when plugged into an external power source. After trying it, this does not appear to be the case.

Leaking batteries is why the batteries should be removed if the device won't be used for over two or three weeks.

Over the years I've ruined flashlights, radios, cameras and a GPSr because I left the batteries in for months. 🙁

Thanks. I'll give it a shot. It's a shame to see the equipment ruined.

If the battery acid & gunk isn't too bad or old you can clean it up.

Make a paste with baking soda & water and using Q-tips apply a little bit at a time to clean up the battery gunk.
The baking soda will neutralize the acid and you should be able to clean the compartment if you are careful.
Don't apply too much or get the compartment too wet, just do one little area at a time.
After you get the compartment cleaned up you can clean the contact points for the batteries with a piece of emery board.

Take your time and you might be able to fix it.

You think you have problems. My batteries leaked. Now I really have a mess. Any suggestions as to how to clean it out?

All I will add is that my 710 draws one half of a milliamp when shut off.
It's the same with the cover on or off.
A 1900 mAh Eneloop would take 3,800 hours to bleed off.
That's 5 months!

The inexpensive rechargeables I tested would lose half their charge in two weeks just sitting on a shelf, not installed in anything.

If anyone's unit has dead batteries in two or three weeks with it shut off I would suggest that something is wrong with the unit or the batteries.

Either way, remove the batteries to prevent them from going dead.

DISCLAIMER;

My 710 has never been shut off for more than three days since I got it, so I don't know for a fact if my unit bleeds the batteries down.
And I won't be shutting it off for weeks at a time to test. 😛

David, I can assure you and the other members that the leaking is being contributed solely by the 610.

Obviously the rechargeable batteries do have internal leakage to some degree but not enough to create a bleed of a freshly charged battery in less than two weeks.

Additionally the problem is not confined to just rechargeable secondary batteries but also to primary alkaline and lithium batteries.

The place where I got my eneloops up here is NICA Battery - nicapower.com - and their site says they stock the new Sanyo 2500mah NiMH "AA" cells. Worth a try although I don't know what their shipping costs would be to the U.S.

Powerex has proven better for me over the Eneloops.

Ok, we can then determine if it's the unit or the batteries causing the biggest problem.

I've been trying to find those Sanyo XXs also with no luck. 🙁

I certainly don't doubt that these things lose their charge quickly, I'd seen them doing this before with the previous batch that I had. But for the test I'll do just that.

I have 2 types, the nimh Energuzzlers, and the 1.5v rechargeable Alkalines. I'll do a test with both sets, and for fun, I'll put a set of freshly charged nimh's in the unit and put the back cover on. When I check the NIMH's voltage, I'll compare the unit batteries with the ones on the shelf. I'll charge them up first, to start with equally fresh batt's.

The Phone shop down the road has Eneloops but is out of stock. I had asked the guy to check into the Sanyo XX's if he could find some, which are apparently better yet, but he said he'd order some eloops anyway.
