How do you know when the battery is fully charged?

When the battery is fully charged the green led comes on, however it is not known to me how this charger differentiate from ni-cd to NMH batteries and they do have different voltage levels when charged. Most battery chargers have a switch that allows you to select the type you are charging, this one does not

When green LEDS light. You must charge batteries in pairs. It will hold 4 pairs (8 batteries) at one time but you can put as few as one pair. It takes a surprisingly long time to complete, and some pairs charge faster than others. Charging batteries must be close to the power input, so you can remove a charged pair and move the uncharged ones up. I'm having good luck with the EBL batteries in my Trackpad, computer keyboards, and wall clocks that won't run at all on Eneloops

When you install a battery or a full set, the light turn on red then amber and finally green. This is full charge.

I check the voltage with my multimeter. The charger I ordered from Amazon charges 4 pairs, 8 AA or AAA, as pairs. When the light for the pair turns green, the pair is charged. My MM shows just over 1.4 volts after charging. Hope this helps.

My experience has been that the light is on when it is working. I don't know if the light goes out when the battery is fully charged.

When charging the red light is on. When is full charge the green light is on.

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.

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....

I misplaced mine for over 3 months. When I found it, the LED lights indicated that it was still fully charged. (I'm glad I found it!!)

On my phone, I see a black area grown as the battery is used. After recharging the phone will chime letting me know it has a full charge. I make sure the battery is seated properly. I can go in stand-by mode for several days and the battery indicates a full charge.

Yes, you push a button and it tells how much charge is left on the battery.

On mine it shows a battery icon. When it begins charging that icon is empty and flashes. When it's fully charged, the icon is full and ceases to flash. Hope this helps.

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

The battery is fully charged when the light is solid green. Flashing green when charging.

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 the battery is in the charger make sure the plus and minus line up, when it is plugged into an outlet the led will light up and indicate what percentage the charge is. Let it charge until the 100% is lit.

There are some LED lights on the unit which let u know when it's fully charged but if u just leave it in your car the charge runs out so you should check it every week or so and top it up if it needs it

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 system should be charging it automatically. If you just now installed the battery, wait 24 hours and it should be fine. You may need to reset low battery warning. See your manual for instructions. If it has been installed since February and now is showing low battery , verify the main power source is turned on.

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.
