I've had J cameras work down to around 6.6 volts. So you have some time but you're getting there.I have used the Rayovac D cells. 7.6 volts is from the exif data. If 7.6 is extremely low when will they drop off?
like Fred stated, you need an sd card in each camera for it to work, this is almost certainly your issue.I checked and the CL Level was 46 but I had forgot to put a SD card in it or someone tried to steal it and because it was cable locked to the tree and they did not want their picture available. The camera indicated 12 internal images. Now I have to figure how to get internals out of the camera. will they connect to the home with the SD card missing? I moved one of the other camera in the system to this location and put this camera where the other one had been located, so we'll see.
I thought that might have been my problem so I took one with me when I went to checklike Fred stated, you need an sd card in each camera for it to work, this is almost certainly your issue.
Probably using the exif data from the pics.
Those heavy drops of 0.4 volts or so only happen with the Powerhouse flash modules while the super-capacitors are hitting the batteries hard to recharge. The standard flash modules (all J cams and dual flash on G and K) are much more orderly in their decline. Your point is a good one and well made though... If you are monitoring the battery level on a G cam with a powerhouse flash module you want to only analyze it by the highs in between the heavy recharging dips.Just goes to show % is useless. It shows BP 50%. Definitely not 50% remaining. It’s also according to exactly when voltage is recorded. I ran tests and the voltage instantaneously drops up to ~1/2volt (per black flash) temporarily when flashing. So if it’s recording volts during dip that’s not representative either. If you’re close to camera voltage shutoff value, that temporarily dip in voltage will switch camera off or to internal pack.

Funny you should mention those numbers. The last external pack of 6 D's I had go down checked out when I got home at 4 batteries with 1.4 volts and 2 with 1.1 volts (7.8 volts). I put the 4 with 1.4 volts in the internal bay of another Powerhouse G cam starting at 4 x 1.4 = 5.6 volts and so far after 1257 pics over 9 days those 4 internals are at 5.49 volts this morning and going strong. I'm assuming that there were two weak batteries in that group that caused the external pack to go down?? Have you checked the voltage on those "dead" batteries? You might find some of them have life left.Yes that’s correct Fred, mine are PH BF.
I get Ext Low @ 7.77v. Not exactly sure where cut-off voltage is. IMO, it may not be a finite cut-off value. If last pic before dying is a night flash, it may take that picture and continue to drain batteries on cap recharge, taking voltage below the normal shut-off value. They seem to dive fast after 50%.

IMO, the specific voltage may be a little different in difference cases. But, in majority of cases an individual “battery- cell” is considered dead or relatively closeI did. Same as you. The internals are 6v and they ran I believe to ~4.8v.

to dead at 1.0 to 1.2v. It is not the overall voltage of the batteries in series. It is simply that there is not sufficient enough chemical reaction to make electrons flow in a single battery.
On a meter, it may show 1.3+ volts, but under a load(ex. 50ma) the voltage falls like a rock. Remove the load and it may well again read 1.3v to 1.4v.
Each battery has its own chemical reaction taking place. If for some unknown reason the reaction is weak, the electrons will cease to flow, possibly at even a higher voltage. When electrons cease to flow you have no current (amperage).
A battery pack in series is only as good as it’s weakest cell. You may can group used batteries as you did and gain some appreciable amount of power, but there no way to know how long they will work by testing voltage. I’ve started changing them all out. I’m using the BP 50% as a rule of thumb to change mine.
If my cameras were closer to home I would do exactly as you Fred. But you have to strategize money vs convenience. If you’re 2+ hrs away and getting 1000’s of pics a month, you have to sacrifice in one way or the other.Yes! This is why you don't want to rely on a standard multi-meter to test batteries unless it has a dedicated battery load test circuit such as the Innova 3320 (what I use). But a good quality small cell battery tester is a reliable and much more convenient tool... no fumbling with probes and rolling batteries.
I've had the k dual cell for almost 30 days. It just recently started taking pics of nothing. Also the report shows 3-4 lines of info, batch is set at 15. Any ideas?

You were correct to use the "Clear" command to delete old pics... actually it formats the SD card which is what you always want to do when you put in a new card. But it's pretty easy to forget to comfirm the "Clear" command by pushing the up or down arrow to finish off the job before moving on. The "Clear" command will not clear your settings, it just formats the SD card.Yes I do. I checked the cam a few days ago and put in a new card. I went to settings and hit clear assuming it would clear old pics off the card. I'm thinking it cleared all settings? Also how do you determine what pics get sent via text/ email? I have the batch at 15.
