How can you tell that the batteries are fully charged without having to put them in your phone?

When you first put the battery in to charge the light will be blue. Once you plug it into the wall the color changes to red. Once it is fully charged it changes back to blue and ready to go at 100%

The instructions are easy... Plug into wall or 12v (lighter) outlet. Batteries will only fit one way into the charger. light will indicate when charge is full. I have not had an issue with leaving them in too long. They will not "over-charge".

Put the battery in your phone and charge it until the phone indicates that the battery is fully charged. Probably a couple of hours. The charge level can be viewed even when your phone is off.

No it does not. Just give status of each battery as its going thru the charge cycle. It probably works this way because you can charge different capacity batteries like AA and AAA in the same charge cycle.

The information I received stated that you can do just that. The battery is a lithium ion and when the charger has completely charged it a light indicates it is full and in standby. I have been using mine for months and love it. Hope this helps and remember amazon has free return policy if you're not happy.

Your phone will show that it's charging... Ex: when my iPhone is plugged into it, the battery icon on my iPhone shows the lightning volt icon.

The charger has an indicator light that shows charge complete - but the batteries do not hold the charge

The battery has a small button on it that you push and little lights will display the amount of charge remaining

Sorry, I don't know. They came fully charged, so you might assume you and recharge them and store.

Honestly, I didn't even check for the date.However, an overnight charging after they were installed in the phone did it's job.Batteries were fully charged.As of yet, no issues.

These batteries do not have a "memory" so they can be charged at any time. They do not need to be completely discharged before recharging.

Yes! It will tell you it's fully charge when the battery is 100%. It will also tell you to unplug the device.

In order to answer this question, I just unplugged my phone. I did not lose any information. I do not have batteries in mine. It must have something to do with the phone line itself

These batteries have the info chip. You will be able to see the remaining battery life.

There is a battery symbol in the LED window (top right) that will indicate the charge level.

Take it out of the charger and put it back in. It's just the indicator light on the charger. If you put it in the phone it should show up as fully charged. I charge my OEM battery in the wall charger all the time without any trouble.

There is a battery level indicator on the battery. You press a button and a series of green indicator lights show how much charge it has.
