how do I know when it needs to be charged and how will know when it is fully charging?

When you turn it on, it flashes red 1-3 times (?). I believe that 3 times indicates the highest level of charge. There is no way to determine the level of charge when it is in use, except that it gives a beep descending in tone when it is out of charge and cuts off. Then when you charge it, a small red light comes on and remains on until it is fully charged, at which point the light turns off.

It beeps at you, and its lights flash when battery is running low, though they shutdown soon thereafter. I can't quantify 'soon' but I feel like it is only a few minutes post notification.Charge is indicated by led being solid or blinking if in need of charge.

It has a blinking red light when the battery gets low. Also, when you charge it, the red light comes on. When fully charged,the light goes off.

I would recommend charging it for between 3-4 hours. There should be a blue indicator light on the side where the power button is that may turn off when its fully charged(if the device is already powered down)

If red light stays on it should be charging. If it comes on and goes off the battery should be charged and ready for use.

You would have to use a battery tester or a voltmeter whcih will tell you if there is still a charge on the battery

I don't know exactly, I just plug it, and leave it. whenever I remember it, I take it off the charge, and it'll be fully charged! If you put it in charge with less than %5 battery life, it'll take longer to be fully charged. I usually charge it whenever I use it, I plug it before I sleep, next morning will be fully charged!

I would charge it for a full 15 hours before using it. They usually come partially charged, so doing a full charge is the best way to be sure.

Mine did the same thing. It is charging, but the software doesn't recognize it. I installed an app called "coconut battery" to tell me when it was fully charged.

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.

When new it comes already charged. When charging you don't need to turn it on.

Once you plug it in, there should be a red light on to tell you it is charging.

The unit comes with a cord that you plug in to charge it. There are instructions that tell you how to do so. There is also an indicator light on the unit to let you know when it is fully charged.

charge it to be safe,when you plug the charge in it will automatically start charging at a lower number and work its way up,you can tell how much of a charge it needs by how long it takes to get back to 100%,you cant over charge it so this wont hurt it,once your sure its 100% only charge it when it gets low,if its fully charged your just wasting electricity!!!!!

The instructions that come with it say to charge it first. I'm sure it may have some charge when it arrives, but probably not full.

They say you should charge it fully. It is the same kind of battery that originally came with my phone and that was the directions for it.

I am not totally sure, if I haven't charged it in a few weeks, I would probably charge it up again. However, the indicator lights make it very obvious what the status is (whether fully charged or not, how much charge is actually left)

The plug that it comes with plugs in to the small connection on the outside of it and once it's plugged in you will see the lights come on indicating how far along the charge is on it. Once it's full all lights should remain on solid. No blinking That little red plug that is attached to the unit is to charge a device not to charge the unit itself. Any further questions just let me know

I don't know. I just installed it and put it on charge until the fully charged light came on.
