Yeah, I saw that Costco sells them but the nearest one to us is about 30 miles so we let our membership lapse a couple of years ago because we never got there!
And Amazon.ca does sell them but I found another online seller for less (there I go with "cheaper" again!).

I found the Sanyo Eneloops at Cosco a few months ago.
Amazon.com sells them also.
The only problem with the lithiums is the cost, they're expensive!

Yeah, you're right, it doesn't make sense to use cheap batteries in an expensive unit! I've been looking into where to get Eneloops up here (unfortunately not at the store where my son works!!) and I"ll be sending for some shortly.
And the Ultimate Lithiums as backups makes perfect sense,too. Boy, I'm glad I joined this forum - you guys keep my head on straight!

If you want rechargeables get the Sanyo Eneloop.
Get the good alkaline, not the cheap off brands.
I've found the Duracell lasted the best of four brands I tried.
The best battery life in my 710 was from Energizer Ultimate Lithiums, and they make the best spares for my Eneloops because they are very light weight, easier to carry 4 or 6 spares.
I always figured using the cheapest batteries in a $550 device was not a very good idea.
Remember to reset the battery type in the power settings page on the unit.
And remember that no matter what you do these things eat batteries.

Thanks Denis, I was just about to buy some 2450mA NI-MH rechargeables (I forget which brand) but now I'll get some of the cheaper alkalines!

Tested with SD card in. 3.?Gb of maps on it .... ! I'll leave that test for someone else, I'm not that curious.... lol !

Great information. Did you measure with and without an SD card? On other platforms SD cards consume a lot of power. Just curious for the 710.

Great readings for the backlight and compass, thanks for that !
Since we now there's a drainage issue with the cover on, I wanted to know simply how long a couple of battery types last. I did a test - backlight on full & always on, compass on, barometer on, detail maps on, highest detail, and enabled image maps.
I have and have previously used Energizer NI-MH batteries and wasn't impressed. With the above settings I found :
2300mA Energizer NI-MH with battery type = Rechargeables -- 5h40m.
2300mA Energizer NI-MH with battery type = Alkaline -- 6h05m.
2000mA PURE Energy Rechargeable Alkaline (1.5v) with battery type = Alkaline -- 7h25m.
A full hour and a half more than the NIMH. And they were still fully charged after about a year in the drawer, the charger would not charge them more. I bought this set of batteries and charger at our local grocery store in the battery section for about 20 bucks, and will start using them in the field instead of the nimh's.
I'll do this same test with a set of normal alkalines, just for comparison with the rechargeable alkalines.
If anyone else wants to add to the test list with Eneloops and/or other types, feel free !

Thanks Brent for those readings. That explains why I am getting just 4 -5 hours with a set of eneloops.
While Geocaching, I use the voice recorder regularly to record my finds (& DNF's 🙁 ), take photos and have the electronic compass on all the time - that's why I got the 610! To switch off the electonic compass to save battery power is not an option for me.

I did not measure the mAh rating for my sample eX610. But about 10 hours with a set of fresh eneloops are, what I used to get.
So I'm within the range. Taking a photo was pretty power consumpting - You measured it.

I did some power consumption testing on the Explorist 710. Below are some of the mA values that I observed. Testing the mA draw was difficult due to widely fluctuating values during the operation of the GPSr so don’t take the following results as 100% correct. Field testing at various settings would give the most accurate results provided you know the exact capacity of your battery. The 16 hour rating that Magellan states is obtainable with rechargeable batteries, but only if the unit is in active suspend mode for some of that time. What type of battery is Magellan referring to in their literature when they state 16 hour run time?
Compass and barometer off:
Display off (0) = 170 mA
Display on (1) = 185 mA
Display on (2) = 216 mA
Display on (3) = 235 mA
Display on (4) = 265 mA
Display on (5) = 292 mA
Display on Full = 323 mA
The compass adds another 35-45 mA.
The Barometer uses very little power and is hard to measure because it may only be taking samples.
Camera on, display on (1), waiting to take photo = 430 mA. Bumps up to 560 mA when taking photo.
Video camera on, display on (1), waiting to take video = 376. Bumps up to 470 mA when recording video.
Recording a memo = 162 – 240 mA.
The following are stable values and are accurate.
Unit off = 1.45 mA There is some drain even if the unit is off.
Sleep = 4 mA.
Suspend = 52 mA (A 2000 mAh battery would last about 38 hours).
To calculate approximately how long the unit should stay on, divide the battery capacity (ie. 2000 mAh) by the mA draw.
Please feel free to add your results during actual field use. One way to tell how long the unit lasted is to start a new track when you add new batteries and when the unit finally runs out of power, look at the time traveled in the Data only page.
