How can you tell when the unit is fully charged? How long does the charge typically last?

The main led light on the corner will glow blue while on, red while charging, and purple while on and charging. When just charging it will turn off completely when full or to blue when done charging while on. I believe it will last aprox 10 hours?

I just got one and the user manual is ridiculously lacking in details. So humor me...how do i check charge status? I turned it on and all lights blinked once. I plugged it in the wall and only 1 light is blinking. How do I know when it is fully charged?

I got a similar unit recently and when I plugged it in, it too showed 100% charged. However, I unplugged the charger and checked the battery voltage which instantly dropped to under 6V. So that told me that the battery wasn't accepting a charge and the "100%" reading was coming from the charger just while plugged in. So I left it plugged in and after an hour it did start accepting a charge and the reading dropped to 60% or such. So it does take at least 12 hours, after that if it starts displaying 100% it probably is charged.

Great question. I jut checked mine - haven't used mine in over two months. Still full charge

This unit stays powered for approximately 5 hours on an ongoing basis when fully charged. However, it is VERY difficult to tell when it has (finally) fully charged. It takes forever.

did you fully charge the battery before starting, using the unit, instructions suggest min 4 hours of charge time, but overnight is best

I've had it for so long that I can't remember exactly. As best I can remember, it came charged or partly charged because I wanted to make sure that it worked. Once I found out it did work, I just let it charge overnight and it's worked perfectly ever since. Could have come 100% charged or 10% charged as there was no way of knowing but an overnight charge for sure made it 100%. I'm happy with mine.

Probably about 1/2 hour to an hour. There is an indicator on the charger when fully charged.

It works while it's plugged in. I believe it charges - just slower - while it's being used. My unit currently is almost fully charged. Make sure you plug it in AFTER you have made a connection. Mine did not connect unless the charger cable was out. If it's plugged in when you turn it on, it will only charge.

When you turn it on, it flashes red 1-3 times (?). I believe that 3 times indicates the highest level of charge. There is no way to determine the level of charge when it is in use, except that it gives a beep descending in tone when it is out of charge and cuts off. Then when you charge it, a small red light comes on and remains on until it is fully charged, at which point the light turns off.

Like the others have said, it does NOT have an indicator to tell you when it needs charging, other than a dimming of the light output. The company does publish a table that tells you how many hours a charge will last, depending on what light setting you use. If you use the lowest light setting, like I have started to do, it lasts 10 hours!

In the directions it says that the red charging light should go off after charging is complete. Unfortunately it doesn't. I let mine charge for over 8 hours and the light remained on. The red light only indicates that it's charging. It will hold charge. Haven't had any other problem with my unit.

I usually charge mine over night after the red light comes on. It does flash continually while it is charging. However, after 8 hrs. of charging, it usually still flashes. To know if it is fully charged or not, just look at the number of green lights that are lit on the handle. If the top one (100) is lighted, it is fully charged.

You need to hold the button for a few secs, you should see a green light on it while it's charging. Hold until you see.the green light. It should be fully charged well before 7 hours.

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.

There is no indicator light that tells you when it is charged. I use mine everyday at work. I try to plug it in overnight everyday. I have had three of these units in the last 11 years at work. They will last @ 5 years if using it everyday like I do.

It wasn't completely charged. We let it charge til completely green. Once it was done we unplugged it and used it til it died to calibrate it then it charged easily after that.
