Pull the battery tabs on the unit out a bit farther, maybe the positive post doesn't stick out far enough with some batteries to make a good contact. I had read that somewhere else in here and it had fixed the problem for someone else.

I picked up a goalzero nomad 7, got a special where it came with 4 batteries, the batteries don't seem to fit the 710 as I can't get it to power up when I put them in, other than that, the charger works great!!

I bought a product on Amazon in the past year. I paid him $ 115 with delivery to Ukraine. It completely lived up to my expectations.
Batteries are very good. They are very similar to eneloop. I use them in the eXplorist.
In the charger, I installed conventional batteries in 2700. From him I charge the camera Pentax W80 and any mobile phone.

With a homemade adapter I charge from 12 volt radios Motorola TLKR T5.

Oh yeah,
I just got a Goal Zero - Guide 10 Plus Adventure Kit as a gift.
It's a portable solar powered AA battery charger.
It came with four 2000 mAh NiMH batteries, when I finish some field tests I'll post my impressions.

My first impression is it's not cheap but pretty cool.
And about as GREEN as you can get!

Hey Phil, here's something interesting to read, up your alley, so to speak. I'm going to bed a little less dumb tonight because of it ! Very informative, and I gotta get me one of those oscilloscopes !!!

:woohoo: :woohoo: :woohoo:........ I love it ....... :woohoo: :woohoo: :woohoo:

It's always good to see that people have the time to do such meticulous testing of a bargain basement charger.
Scroll back on this thread to about 8 months ago. 😛
I have and use a Powerex - Maha C9000 Charger-Analyzer for all my rechargeable AA batteries.
The Sanyo NC-MQN06U charger stays in the truck just in case I need it while on a week-end trip.

Since I retired I can't use the RailRoad's oscilloscopes and other cool equipment for my own experiments and tests. 🙁
While I was repairing and testing equipment for the RR I would set up my own tests and experiments in the shop also.
Now that was pretty cool, I would be getting paid overtime to fix the RR stuff and still be able to do my own thing at the same time! :laugh:
But I'm not obsessive enough to devote that much time & energy to test a cheap charger to that extent, whether it's a Sanyo, Presidents Choice or any other brand.
My anecdotal evidence comparing chargers told me the the Powerex - Maha C9000 charger is the one to use.

I mean, big surprise!! the cheap ones are not as good as the expensive one!! :ohmy:

You get what you pay for, most of the time. :blush:

For what it's worth I use the C9000 charger, the Powerex 2700 mAh batteries and the Eneloop 2400 mAh batteries.
Why buy a $500 GPSr and worry about a 20 dollar charger & cheap batteries?

That's true, and I'm not gonna strip one of the batteries down to the core just to prove that they are or aren't eneloops. However, they are 2000 mAh, and they're LSD (not the drug -- Low Self-Discharge), which are comparable with the Eneloops. And my limited experience with them confirms they are a far superior battery to the crappy Energizers. They hold their charge for weeks, and they don't die with 2 hours of use like the other ones that have now been, um, recycled.

I agree that they could be knock-offs, but I'm optimistic they're genuine, seeing as they came in a Sanyo-made charger, which is marked as PC on the front.

The charger model number is Sanyo NC-MQN06U, the batteries are marked as Pres. Choice NiMH Precharged... Product of Japan... Loblaws Inc. At least they came from the right country !

Um, that confirms that the charger is made by Sanyo.
That does not mean that the batteries are Eneloops.
A Sanyo charger with 4 Eneloop batteries cost about $30 - $35 at Cosco.
No wondering/hoping it's not a cheap knock-off. 😛

I just looked at the back of my President's Choice charger, and it's made by .... Sanyo ! So that basically confirms that the batteries are indeed Eneloops ! So for $20 on clearance you get 4 eneloops and a charger at any Your Independant Grocer store !

i had the light set for max intensity and time on, i checked it every hour or so. i also had the power save turned off.

That is what i am finding out. After a couple of cycles my batteries seem to gain power.

I have had a set of these for 2 years now I can't say how long they last in 710 but they do seem to last a long time and don't seem t loose power when not in use, They are 1.2 V & 2600 mAh with no memory and come with free case.

I just got back from GeoWoodstock-IX and while on my week & a half caching trip I tested the
PowerEx MH-C9000 WizardOne Charger-Analyzer + 4 Pack AA NiMH Rechargeable Batteries [2700mAh].
I found them on Amazon.com

So far these are the best rechargeable batteries I've tried yet! :cheer:
It took about 40 hours to do the first charge/break in.
After that I got about 8 hours of use in my 710 with the batteries.
Then the recharge took about 2-3 hours.

The charger analyzes what the battery needs and charges it accordingly.

These are a bit expensive but I would recommend them.

Go to this thread in the forum - Battery

It's a pretty good external battery, I got one from Amazon.com and it will power my 710 for at least 25 to 30 hours!

Is there any way to use an external battery pack?

It would be nice to have a wire connection to an external pack that could be kept outside the unit somewhere like in a pack, etc. Then you could keep brightness, sound, etc. on max and all features enabled and never worry 🙂

How long do the batteries last when you are using the GPSr?
You tested them just sitting there doing nothing with the backlight on.

My Eneloops will last about 10 hours in my 710 when I leave it sitting there doing nothing.
In my Explorist-GC after 15 hours they were not quite dead.

But if I'm out creating tracks, following routes, using the electronic compass, checking the map, changing the map, reading descriptions of caches, and finding geocaches with it the Eneloops last about 3 to 4 hours.

Lithiums last about 6 to 8 hours, alkalines last about 4 to 6 hours.
With my Explorist-GC GPSr I got about 4 hours more battery life than the 710 does, with all battery types.
If I take pictures/videos, record audio notes and record log notes the batteries will last about 1 hour less.

Everyone's mileage will vary but the batteries will die sooner than you will expect, carry two sets of spares.
I always have a set of rechareables and a set of lithiums as spares.

What I found out, at least as important as the accu type is the charger.
I'm using a BC700 lately, and it improves the power of my accus far more then I thought. It even increased the voltage from 1.46V to 1.52V.

I'd hazard a guess that good alkalines last as long as these things. I'll have a better idea soon enough, going for a day of caching next Sunday (1 week). I haven't even put the lithiums in it yet, saving them for a special occasion or extended bush trip. at ten bucks a pair, I'll hold onto them for a bit....

Look at my post on ExploristGC - General - power consumption.

Basically, these things eat batteries no matter what you do.
The rechargable batteries won't last as long as lithiums.
