How do you know when the battery is charged? Does the blue light go off on the charger?

When the battery is charging it will start as red and transition to blue. Once its blue its charged. The light will not shut off.

When the light is either red or some shade of pink/purple the battery is charging. When the light goes blue the battery is charged. I believe that once the light turns blue the charger stops charging the battery, but the light remains on. The blue light never turns off.

The blue lights (three of 'em) eventually all stay solid blue instead of flashing blue (still charging).

After the battery is fully charged the light will turn blue. It is when you charge the battery in the charger dock. But if you charge the battery via the USB port, the light will be always blue and you can see if the battery if fully charged in your phone indicator.

When the battery is fully charged the light will turn blue,it won't shut off. You have to take out the battery when its blue. Again the Light does not shut off. The only way to shut it off,if you take out the battery.

When you press the on button a blue light appears; when it is charging it is red; when it comes to a full charge I THINK it is green. I just took it out of my purse and plugged it in so I know the first two are correct and I have to go by memory for the full charge. I hope this is helpful. I do love this charger - so much that when I left mine in a hotel room last year I got on Amazon to order 2-3 as spares - even though I purchased over 3 years ago originally!

The light should turn red when it's plugged in. It will turn blue when fully charged.

There should be two positive/negative contact markings on the battery. Make sure those line up with the contacts on the charger. The light should turn purple once an uncharged battery is put in correctly. When not charging a battery the light will be blue. Here's a picture: http://imgur.com/uYFAktx . It's upside down in that photo to accomodate my other plugs, but you can see how the battery is oriented.

The light will turn blue when its charged! And if you notice, the charger gets a bit warm while charging but when it has finished charging the battery it cools right back down! Won't fry it st all!!

When you first connect the battery the light turns red to show its connected properly. Then when you plug into the wall it flashes blue. When it is done charging it turns solid blue. It takes a long time, but worth it if you charge them ahead of time and take the batteries with you. I charge them overnight. Hope that helps.

There is a little LED light that changes to blue when fully charged. The unit very simple and works.

Never timed it. But the blue charging light goes off when it is. But it holds a charge forever and many uses..

I don't think the light color is a working estimation of whether the battery is charged or not. I believe mine is always green, I usually look at the light strength to monitor it when its charging.

The red light means the battery is still charging. A blue light indicates a fully charged battery.

When you plug it in to charge, you'll notice a small red light will show meaning it isn't fully charged. Once that light turns blue then the charge is full.

I dint know exact but I know that the blue light, when it stops flashin, it means is done charging. It takes me like 12-24 hrs to charged or more sometimes. The charger hold for me like 1-2 hrs or more .

Yes, the light will turn blue when charged. Mine turns from blue to "off entirely" after a while if I leave it plugged in and it's already fully charged.

usually when you charge it , it should have a blue / red light that pops up. if it doesnt, it can be broken or you didn't charge the charger yet (:
