You just need to click the button near the indicated lights. It will show you remain battery level, 4 bars means full power. If 1 bar left, you have to charge it .

No, there was no indicator on it to show how much charge is left, but there are red and blue light showing whether the power is full or not.

It does not have a battery level indicator but the batteries do last a long time compared to the non-lithium 18-volt devices I have had.

Yes, I'm not sure but I had it running for about 3 hours off the charger and I had no notification saying that the battery was low

Yes, but you should call your security system company and verify, they can tell you if they need to reset the system and they can also tell you if the system shows a full battery.

There is not a low battery indicator, but the LED on the inside will start to get dimmer. You might also notice the need to turn the volume up higher as the battery wears down. With a standard alkaline 9v battery most people report 40-50 hrs of play time. Or if you use a rechargeable nimh 9v battery roughly half that per charge.

Does NOT continuously indicate battery level. Does indicate 3 states: 1) red - low battery, 2) steady green - charging, 3) blinking green - fully charged and may be removed from charger.

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.

There are values 25, 50, 75, and 100 next to a button on the top face. When you press the button the values light up from 25 to 100 then stay lit for the percentage at which it is charged. So, you know that it is fully charged when all four values stay lit. (also for example it would be at least 75% charged if all but the value 100 stay lit)

Not that I can tell. It is where I store it and the battery is working for me

I have an indicator, and it shows that the battery is going down. I haven't let it get to the point of running out of power.

Sorry. I don't have this unit anymore, so I can't check the battery. Even if I did, I don't understand the question, if there is a question there.

When the G3 is on, press the on/off switch and a battery level indicator appears along with the date and time. Just press the button -don't hold it down as you do to shut it off

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

That's the question? "Battery level indicator?" Usually what happens to me is that I am suddenly out of battery, without warning. However, I always have two batteries with me, one in the camera and the other close by. There may be a way to check it, but I have never hunted for it.
