When you plug it in, a red light comes on. When the light comes off it's charged.

Simply plug the USB cable into the device and the other end into the USB port on your computer and it will light up to indicate that it is charging and the light will let you know when it is fully charged....easy and charges fully in about 4 hours....

You don't really know when it's fully charged. I still don't. I just charge it whenever I can for as long as I can. I've come to realize that if it isn fully charged, it will not charge your phone. It will just hold your battery in the same place for a few minutes longer but it will still go down.

Mine has a red light that comes on and stays on while charging. I will update when it's done charging to let you know what it does. OK, after charging the red light went off. At that point I disconnected from the charger and reconnected it, the light came on for a second and went right back off so it looks like you're fully charged. Hope this helps and enjoy!!

There is a battery level indicator on the battery. You press a button and a series of green indicator lights show how much charge it has.

When you plug in the battery the little green light will come on to let you know it's charging. When that light has turned off then the battery is fully charged and you can put a new one in.

To really see if the battery is really "full", I'd unplug the AC charger, wait 30 seconds, then push the "battery test" button again. If it still reads "99%", the battery is really charged. If it goes to "65%" or such, then it needs more.I base that on having got one and when I first plugged it in, it instantly began flashing "FL". However when I unplugged it the display instantly went to 10% or such showing that the battery was resisting the charge and the "FL" reading was false (just coming from the chargers power only while it was plugged in). So don't be fooled into thinking it's full that fast, yet 5 hours is a lot more than under 5 minutes (where it may have taken in some power, but it may still need more).

Mine did the same thing. It is charging, but the software doesn't recognize it. I installed an app called "coconut battery" to tell me when it was fully charged.

On the bottom of the battery there are some gold/brass squares. Line those up with the similar squares on the inside of the charging slot. If inserted correctly, there will be a red light, indicating that the battery is charging.

I just use the indicator on the camera, which will show full charge until the Smartree drains and the camera kicks over it it's main battery. They you know the Smartree is empty.

Not that I can tell. Mine just starts charging when I plug it into my car and stops when the car battery is fully charged.

It doesn't have an indicator that shows when it is fully charged. With that said, I have never had it die on me. It seems like it gets almost 8 hours of use.

I am not totally sure, if I haven't charged it in a few weeks, I would probably charge it up again. However, the indicator lights make it very obvious what the status is (whether fully charged or not, how much charge is actually left)

The indicator light does change to show that the battery is fully charged. I haven't used my charger in a couple months. So, I don't recall exactly what the light does. If memory serves me well, it actually blinks red when charging, and shows solid green when it is done charging.

When mine blinks it is charging. when it stops blinking it is fully charged.

You would have to use a battery tester or a voltmeter whcih will tell you if there is still a charge on the battery
