How do you know when batteries are fully charged

There is no indicator. I leave them for about two hours. You can leave them overnight but it does not make a difference.

My lights turn green on mine. I have 2 of them and they both work the same way.

There is an LED light. It's green when they are ready to provide charging, orange (hard to see it different than red) when the batteries are low, and red when the batteries don't have enough charge to charge something.It stops charging the batteries when they are full. The light also says when the batteries are done charging. It blinks when they are charging. What the light says is printed in the bottom of the unit.

When I charge I am able to see each LED glow before it becomes fully lit. When all 4 are lit, it is fully charged.

When its plugged in to charge, turn it on and the battery icon will show you by blinking.

I haven't used my new Charger long enough to answer correctly, but it has a box at the bottom that tells you when the battery is full charged, it may turn green, but I cant verify that yet. sorry.

I got a similar unit and when I first plugged it in, it too showed "fully charged". I then unplugged it and checked the battery level, but it instantly showed 0V. So that told me the "full charge" reading was false and the charger was giving me that reading while the battery seemed like an "open circuit" and was not accepting power yet. So I did leave it plugged in and within 1/2 hour it began dropping the reading to show 65% charged or such which I knew was more realistic. So despite getting that "full charge" reading off the bat, it does need the charge time. I got a similar unit and when I first plugged it in, it too showed "fully charged".

There is just the 2 red LEDs and 1 green one for the "charge level" indicators, correct? If so then seeing both red and the green LED come on when you push the test button does hint it is fully charged. If this is the first time you've charged it (where it can take 24 hours to charge), then I'd double check that it's full by pulling the plug on the charger and then push the test button again after 30 seconds. You should still get the 2 red LEDs, but probably not the green. If you have a volt-meter you can also check the battery voltage on the jumper cables, full is ~14V with the charger plugged in and without it plugged in it should drop to ~13V and hold there. If you suspect the battery being bad, then the way to test it is with a known load and see how low the voltage goes. For example, I plugged in a spot-light that pulls ~4 amps and a good battery had the voltage drop to 12.4V instantly and very slowly dropped the longer I had it on (like after a minute only dropped to 12.3V). A bad battery instantly dropped to 11.2V and within 30 seconds went down to 10.5V. That's how you can tell if it's really bad.

When the battery is charging, there is a flashing amber light. When fully charged, there is a solid amber light. Hope that helps.

The indicator on the charger will change from red to green that tells you that the battery is fully charged.

All you have to do is plug into the wall and put your batteries in the container. The side bar will let you know once the batteries are fully charged.

Put the battery in the charger. Usually get some type of indicator light that it connected and charging. It seems like the batteries take 5 hours to fully charge.

Your charger should tell you when it is fully charged, mind have yellow light when it needs to be charged and a green light when it is fully charged

A. Put the batteries in the charger in the right directionB. Push the grey button to "discharge the cellsC. Wait until the cells indicate fully chargedI leave my batteries in over night.

Just insert the batteries into the charger OBSERVING PROPER POLARITY (battery + to charger +) and wait until the charger LED goes from red to yellow to green. When the charger LED is green, the battery is fully charged.

Yes There Is A LED That At First Flashes Red When It Is Plugged In To A Power Source, Like Your Computer Or Your Laptops USB Port, Indicating That The Batteries Are Being Charged. Then The Very Same LED Flashes Green When The Batteries Are Charged. & As Thomas Battle Said "and there is a steady green when fully charged."
