How can you tell when the spare battery is fully charged. Does the LED light change color or start flashing?

Yes it turns green when it's done charging, red is when it needs 2b charged & yellow is when you don't have the battery on correctly.

Mine has a red yellow and green light across the top and in the shape of a small battery. This is to ley you know you know the condition of the battery. Red is needing charge,yellow is to let you know caution and the green is full charge. And none should be lit unless you press the check battery button. I hope this helps answer your question!!!!

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.

The blinking light is when the battery is charging. The solid red is when the battery is fully charged.

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.

If you are charging the battery from empty, when you plug it in only 1 light will be blinking. After some time charging, it will be 2 (1 on, 1 blinking), then 3 (2 on, 1 blinking), then 4 (3 on, 1 blinking). After some time all of the lights will go off. That is when it is done charging. As this is a high capacity battery and usb is a low input source, it takes a long time to charge (as would any other backup battery that's charged via usb). Just give it time.

It is normal. It means your battery is currently at less than 25% charge. As it charges, assuming it is a good battery, the 25% led will become solid and move onto 50% flashing and so on until the 100% led is solid. Then the battery is fully charged.

My new battery was already charged and I used it right away. Then when I loose a bar I charge it about 20 min. when the battery light stops flashing which indicates the battery is fully charged.

I believe there's a light that flashes while it's charging, but it remains solid once it's full charged. It takes several hours to charge completely.

The battery does not make any noises. The LEDs flash and light up as the battery is charging, and is solid blue all the way across the battery when fully charged.

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.

No. It sounds like a defective unit. The LEDs should only flash when charging.

When you turn it on it will flash a light twice indicating the battery level. Just look to make sure the light is green. It will change to yellow or red (I can't remember which) when the battery runs low. My battery lasted a very long time, 17 months before I had to change it.

Here is a link that fully answers your question. http://www.batterychargers.com/Documents/0099001192WB-00.pdfBasically when the YELLOW LED flashes, the charger has aborted the charge as the battery may no longer be capable of taking a charge and must be replaced. That said, it is a good idea to reset the charger and try the charge again before replacing the battery. To reset the charger merely unplug the charger from the wall, wait a minute, then replug it back into the wall...If the light stays SOLID ON and yellow, then it is charging...it may take a while...if it faults out again and starts flashing yellow again, then replace the battery. GOOD LUCK. and I am most sorry for your the loss of you husband.
