Does this mean the batteries are not strong enough

hi Kenny.
With most cameras, an amber, yellow, or red light indicates a battery that's currently charging. A blue or green light usually means the battery is charged. A blinking light sometimes indicates a charging error; other times, it indicates a battery that is still charging.or faulty battery.
have you tried,take the battery out and then put it back in?.
make sure the battery is seated.and its making a good contact.

When your flash light (I mean the part that gives the flash) or the capacitor that stores the power for the flash are defect. you won't see a flash. When a red light comes on, when actually the flash should fire, the most likely the capacitor is defect. The electronics sensed it could not reach the voltage needed to fire the flash.
It also could mean your battery can't deliver enough to charge the capacitor, but is that was the case the battery indicator should tell you.

This a situation the manual not even mentions. The red light on the bottom right of the camera is the memory access indicator. It should light green as I remember ok. And blink when it is writing to or reading from the memory. If it is red, it means : this is not ok.
This light is not a gadget. It should be taken serious. As long as it is burning, of flashing you are not supposed to switch of the camera or to remove the memory card. If you still open the memory compartment or switch of the camera or remove the battery, while the camera indicates I'n accessing the memory, serious damage can occur to the memory card.
You could lose all your pictures, because of it.
I would suggest, make sure your battery is charged correctly.
Format your memory card in a PC with FAT 32.
Check if al contacts in the camera are clean and shiny. (Battery and memory card contacts too)
The place the battery and the memory card in the camera and try switching it on again. If it should start, first do a format of the memory card in the camera before you starts taking pictures, of the camera has its own format and can make a folder.

You should be able to switch on the camera without a memory card inside. The camera will us the internal buffer, to let you take a picture in DEMO mode.

I hope the red light does not indicate your internal memory is corrupted. Because if nothing helps and the red light comes back, I think you should contact a Canon service centre.

The MSDC indicates that the camera has recognized it's connected to a computer.

The red light indicates that the camera's battery is charging.

Make sure that the batteries in the camera are good and turn it on. Is there a light that comes on to let you know that the camera has power and is ready when you press the power button? Does that light come on and what color is it?

If the light ends up green, then you know the batteries are good and the camera is functioning properly and is ready to take a picture. If this is the case, then after you turn it on - look on the back of the camera for the focus zoom in and out buttons. Sometimes they look like a switch that you can rock right or left. Press the switch and look through the lens. Does press the switch or arrows in either direction clear up your view and allow you to see anything? Are you looking through the lens hole or are you using a small screen to view on the back of the camera? If you are looking at a screen on the back of the camera and that screen is black - it means that you dont have the exterior view option turned on in the cameras settings. Sometimes there is a button labeled "view" on the back of the camera to alternate from the exterior view screen on the back of the camera and using the lens hole view at the top. Press that key to make the view screen turn on. If this option is not turned on yet, press the menu key on the camera and use the arrow keys to scroll through the option choices until you find the image preview choices and turn this option on. Then save this choice and close the menu features to see if it comes on.

If you are not getting a power indicator light when you turn the camera on, then replace the batteries. If the light comes on and its something other then green and steady - (like red and flashing) check your camera manual to see what this indicator means. Some cameras show a red light that is flashing when you turn them on to indicate that the memory card is full. Some camera have a red light that is steady to indicate that the battiers are almost out of power and they will show a picture on the digital to indicate how much power you have left before they shut down. Each model camera is different according to the options it came with.

Maybe the Nikon replacement batteries you buy doesn't carry strong enough power for your Nikon Coolpix Camera .

HI. The red line is an indication of a defective battery. This defective cell cannot hold a charge strong enough to power your phone properly. The necessary actions are to replace the battery with a new one. This will correct the issue.

Ok, there are several things to consider. First of all, don't use standard alkaline batteries, the flash needs a lot of power and will drain those quickly. Use either lithium batteries (most powerful non-rechargeable) or invest in NiMH rechargeable batteries. Those would be your best choices for AA's.
Now to your flashing red lights - on the Speedlight flash they fulfill 2 functions, one is as auxiliary ready lights (if used as wireless remote flash) but the blinking in your case points to their other function - it blinks 3 times to indicate possible under exposure of your photos at maximum output level. It's basically telling you that the flash was not strong enough to properly illuminate the scene you tried to shoot. That doesn't necessarily mean the batteries are going flat, but you could simply be out of range of the maximum flash power. Your flash has a guide number of 30 - that means at a zoom head position of 35mm (if your lens is at 35mm) and your ISO is 100, then the maximum range of the flash is 30m (approx. 68ft). If your subject is further away, you would get an underexposure warning (3 blinks of the ready lights).
Hope that helps explain some things.

Sorry, but this indicates very strongly that your battery is completely dead. To confirm this simply wipe the terminal of your battery very well and hold the terminals of the battery to your tongue. If battery is working, you should fill a sensation in your tongue at the instance of contact, otherwise you just got the confirmation you need that your battery is dead. I mean dead, not low, but dead. Change the battery.

Hello,
Here's a copy from the owners manual:
■ Charging LED 
Red LED is on = Being charged 
Red LED is blinking = Charging error 
Green LED is on = Carging is complete


● If the charge indicator blinks as red, it indicates a battery charging error.
- The battery is not properly inserted
- The terminals of battery are dirty or damaged
If the battery is inserted properly and the charge indicator continues to blink, contact the
nearest Samsung Camera Service Center.


Another charging error is when the batteries are so depleted, they won't charge up to 100% anymore = red light doesn't go out and remains on for too long, means get a new battery.
