How Do You Know When Your Camera Battery Is Charged?

Every new battery must be charged to 100 percent before you put it in the camera and use it either for a day’s work or for your amusement. So, take a look at the user manual before you get started. This will give you an idea about what to expect from the charger’s indicator lights (critical to the charging process), how long it takes for the battery to reach full capacity and what the lights look like in the aftermath.

Most Nikon battery chargers flash a solid green light when the battery is charging and it turns off when the battery is fully charged. Ring chargers turn on one red and one green light while the battery is charging and once it is done, the green stays solid. GoPro has a red LED on the body of the camera which stays on solid till the battery is charged. Canon chargers flash a solid orange light while they are charging and it turns green once the battery is completely charged.

There are some ifs and buts to the charging process too. If you don’t understand the specific by checking out the user manual (or this post, if you can’t find your manual), you might risk keeping the battery in a damaged charger and destroying it. Some of these bad chargers or bad charging techniques can also cause short circuits and fires too. Wouldn’t want that now, would we? So, keep reading.

How Do I Know When My Camera Battery Is Fully Charged?

The answer to this question differs from one manufacturer to another. Some camera battery chargers have a range of indicator lights. They move from one color to another as the battery charge keeps increasing.

On that spectrum, the final light is sometimes the indicator that the battery has been fully charged. Sometimes, it is a whole new color. But some manufacturers have only one light on the charger. It changes from, say, red to green once the battery is fully charged.

Sometimes the charger light will just switch off indicating the battery is full. Look up the amount of time your camera battery is supposed to take to reach full capacity in the user manual and around that time, keep an eye out for the change.


Let’s talk specifics now. When the battery starts charging, in most if not all Nikon cameras, the power-on lamp flashes green and stays solid while the battery is charging. And once the battery reaches its full capacity, the indicator light turns off and you can unplug the adapter from the wall socket. Disconnect the USB cable and put it all back in the bag.

Typically, it takes about two hours and 20 minutes for the battery to reach full capacity when the battery is completely dead. If the light does not flash green right away, it is possible that the adapter or USB cable is not connected properly.

So, it is important that you plug in the adapter that comes with the camera to the charger’s AC adapter. For some models, the plug adapter and the charger’s AC adapter come permanently bonded. In that case, you don’t have to worry about it.

If the light does not come on, that could also be because the battery is damaged or that the temperature of the room is not fit for charging.


Here we are dealing with two types: Spotlight and Stick Up. But the indicator lights are the same on both and the way they work while the battery is charging is also the same.

The battery of a Spotlight Cam can be charged with a common micro-USB cable. This is usually orange in color and is in the box. This can be plugged into any USB slot like the one on a computer. Remove the battery from its compartment by pressing the white button and lifting it open.

Connect the orange micro-USB cable to a port and if everything is well, you will see red and green lights (one each) switched on. That means the battery is being charged. When the battery is full, you will see the light turn into a solid green and it stays so till you disconnect the cable.

Put the battery back in the camera and double check the battery levels. It will take about a minute for the camera to start. That’s normal. It takes these batteries anywhere from five to 10 hours to reach their full capacity.


Considering there are many GoPro enthusiasts and not all of them love to read, there are quite a few video tutorials to guide them through the process. GoPro recommends switching the camera and other connections like Wi-Fi, GPS and voice commands off before you start charging the camera. You must also disconnect BacPac accessories if you have any attached.

Unlike the other models, you won’t be removing the battery to charge it. But you do have the option of using a wall charger or a USB cable. The wall charger has a 5-volt, 1- or 2-amp output and the USB port must ideally be a standalone port and not connected to a hub or a standalone monitor.

If you are using a desktop, connect it to the port at the bottom of the tower. If you’re using a laptop, make sure it is a good port which can give enough power supply.

When you start charging the battery, you will see a red LED switch on the front of the camera’s body. You must keep the camera off till this light switches off. It does so when it is done charging. Typically, this takes about two hours with a wall charger and four hours with a USB port. If you’re charging a Fusion model, that takes longer. If the LED light does not switch on, you can check the GoPro website for troubleshooting options.


Canon battery chargers are usually LC-E6 and they are the perfect match for the LP-E6 battery pack. This combination works for several EOS and Mark models. Now, there are a few things to note about these chargers.

They have two indicator lights on them—orange and green. When you plug in your charging cable to the adapter and that to the wall socket, if everything is well and good the orange light will be on. Now, here’s where it gets tricky. Some chargers blink while others show a solid orange glow.

You might see the orange light blink rapidly either when you are charging it for the first time after buying it or when you are charging the camera after a long time. Sometimes it will blink at regular intervals. That might mean there is some trouble and here’s how you know it.

When the battery is on standby for a charge or when it is charging from 1 to 49 percent, the orange LED blinks once every second. When there is a communication error, it blinks rapidly. When it is charging 50 to 74 percent, it blinks twice every second. When it is 75 percent or more, it blinks three times every second. When it is fully charged, the green LED lights up.

If you see the orange light blink rapidly, plug in the charger into an outlet with the battery in it and wait for 20 seconds. If it blinks once every second for a little while and then the charging stops, you can continue till the green light turns on. If it blinks rapidly, remove the charger from the outlet and take the battery out. After 10 seconds, try it again. If it comes down to once a second, it will start charging.

Try this three times. If the blinking doesn’t come down to once per second, you should take it to the Canon support center.
