Will this battery work with DR-680?

The Xuma Portable Power Pack specs state "6000 mAh" it doesn't state @ what voltage; I suspect 5V, which would be approx. 30 watt hours (Wh). I used a 80Wh battery with a 680, in my record-time tests, that gave me about 7 hours. (4 trks., NO Phantom Pwr., fully charged 'new' (not conditioned) battery.
Would the Xuma Portable Power Pack work? Yes, but not for that long, assuming 30 watt hours, especially with Phantom Pwr. engaged. You would probably need three or four to safely go a typical 12 hour day. It also doesn't state charge time, which is usually 12-16 hours with budget chargers. I think the Xuma batt. iis more designed to run a tablet or smart phone.
If your on a budget, I would recommend a 6800 (or 9800) mAh/12.8V liPo (lithium polymer) rechargeable battery on eBay (from China). I bought two for aux. power for about $25.USD each, I ran those for a week and to test and worked good. They even had the right sized DC coax plug for a 680 (5.5mm x 2.1mm; center pin hot) FWIW, Radio Shack o' shame's 'M' sized solder-on DC coax plug is 5.5mm x 2.1mm if one needs to be made, however I used right-angle cable/plug, which is a lower profile and can be easily gaff taped for added security.

Yes, I have one of those and will run a 680 the good part of a 12Hr day.. VMMV, depending on Phantom Power, actual record mode time and other variables. A caveat is, it can take up to 16hr.s to fully charge from a near dead state.
It should be noted, that when the external battery gets very close to depletion & machine auto shut down, and the internal batteries are also low, the recorder can crash causing the loss of the take and arbitrarily resets the take counter to 009 (as I recall) so overwriting of files 'could' be possible.. if this does happen, start a new folder. Recommendation: Keep fresh internal batteries installed and change the external battery before auto shut down would occur. (This is a quirk of the machine and could happen w/ any external battery)
Otherwise, if external power loss does happen, (cable accidentally unplugged for instance) the 680 auto-switches to the internal batteries.
 
Okay, thanks, Rick. I plan on keeping a freshly charged set of Eneloops in the unit at all times. BTW does this battery unit have all of the cables I need to get going?
 
"does this battery unit have all of the cables I need to get going?"
Yes. Plug it in and go
Regards, Rick
 
Rick, or anyone else: Can someone tell me the proper charging instructions for this battery I just bought: http://www.ebay.com/itm/151402106391?_trksid=p2060353.m2749.l2649&ssPageName=STRK:MEBIDX:IT At first I plugged it in overnight with the green light on the plug lit up thinking when it would go off it was charged but I don't think that was right. Now I have tried plugging it in with the switch turned on on the battery and a red light on the switch is on... Would it kill them to print a tiny page with printed instructions?... Thanks.
 
Instructions?
Anyway, I recall reading: plug the charger into an AC outlet, plug PS's cable into the battery. Turn the battery's power switch on. The PS's GREEN light should illuminate. When the green light extinguishes, the battery is fully charged.. BTW, it takes about 16 hours (estimate) if the battery is fully discharged. The charger's RED light is illuminated no matter if its plugged into the AC or the battery by itself (if that's switched on).


addendum: .. I don't think the connection sequence makes any difference, as long as the green charging light is on..
.. To check the charge, (you could..) connect the (unloaded) battery to a DC volt meter, it should read around 12.5V or slightly more. The batt. also has a breaker if the voltage drops below 10.8V to prevent damage to the cells, as I recall.

Thanks, Rick. I either have a faulty unit or dc cord (the one that goes to the device you're powering). The green light is off on the wall plug and the light is red on the battery (which is switched on). I charged it about 16 or 17 hours like this and the red light turned off on the battery and I unplugged it and tried to power my dr-680 and no dice...
 
It 'sounds' to me like the batt. is fully charged but not getting power to the recorder (a faulty coax<>coax cable). They're cheap (cost/quality) anyway and I've replaced the one's I had w/ right angle connector cables. You could try another cable and/or get out the multi-meter to know for sure. I'm sure the seller would send you anther cable .. if that's the problem, rather than exchanging the entire system w/shipping/handling costs.
 
Thanks, Rick. I'll buy another cable... Another possibility is that (with their amazing Chinese quality control) they may have reversed the on/off button? I tried switching the unit to "O" and plugging it in and the green light is on on the power supply and a (dim) red light is on on the unit...
 
"I tried switching the unit to "O" and plugging it in and the green light is on on the power supply and a (dim) red light is on on the unit."
- I hadn't experienced that particular behavior with any of the four batteries I had. I still have two and I just double-checked those. Their behavior is as I previously stated.
