Yes, the case can hold a second battery. I just checked using one of my 4.0 amp hour batteries. There is a place for it to the left of the charger.

I believe what your asking about is when you are done with the number of charges it says, can you use it again, so I am going to answer that question. If it holds, let's say, 2 charges for your phone, that means you can use it to charge your phone twice to full without any outlet needed. After that, you will have to charge up this battery pack again, and then you will have 2 more charges. After a while, the amount of charge it hold may get lower, so it may eventually only charge your phone once before needing to be plugged in again, but you can continue to use it. If that's not your question, I'm sorry, but then I'm not sure what you're asking! Hope this helps.

I can't say exactly but if mine has sat for awhile unused I turn it on to see how many lights come on. Fully charged is 4 lights. I use mine a lot.

I would not since the charger senses your battery and goes to float when it reaches charged state so with 2 it may overcharge a battery, also this is a very low amp charging system so it would probably not do the job on 2 batteries.

It can charge up to 4 batteries at a rate of 6 amps each. A 20 amp could do the job if you are not charging 4 packs at full capacity at once. A 30 amp power supply is a safe place if you are going to charge multiple batteries at once. Here's a good 20 AMP supply. Racer's Edge 20 Amp, 13.5V DC Dual Output RC Power Supply with USB

It almost doubles it. It's worth it though. Mine can go for two day before I have to charge it again.

You can carge up to 8 at a time and they all have the same charge. I haven't had any problems with the charger. It just depends on the batieries you get for it. You can charge aAA's and AA's. If you have any other questions feel free to ask.

I would not recommend it, not enough juice to charge two batteries, but cheap enough to buy more than one, they are worth the money

To the best of my recollection not more than 5 times. I have not had the battery that long. The only fly in the ointment is that it takes a bit longer to charge this battery vice the OEM. The price was right and with two batteries you'll never have to worry about running out of juice.

Only one. Be sure to use the usb charging/sync cable it comes with. If you use another charger with a mini usb connector, the case will overheat. Other than that it works great. Absolutely doubles the battery life of the iphone.

You can charge 2 or 4 batteries, but they must be charged in pairs. You cannot charge 1 or 3.

Still don't know! It still works, I probably have about a hundred charges in it by now, but it's still going strong!

It depends on the device you're charging and how drained it is. However, for standard reference, we generally get 3 charges out of it with an iPhone 5S when it's down to about 20%.

I use it to charge 3. Cannot recommend. Does't hold charge very long. Buy different one.

Not really sure but I can charge my IPhone 2-3 times per charge and I've had mine for two years and recharge it weekly.

1-2 depending on use. Over time the battery life gets shorter. After one year of use we were having to charge it every other day, and we only used it for the sound, no shocking. Shortly after that it wouldn't hold any charge at all.
