Casio EX-Z18 my Casio EX-Z18 charger light keeps on flashing. When I put the battery in the camera, it doesn't turn on.

new battery flashing red light means bad battery

Put the battery in the charger until the light turns green. Eh?

I found this while trying to solve my exact same problem.. It worked for me after about 7 times. Some other people on the site said it worked for them after 20 times. Good luck!

My NP 20 gave me the flashing red light of death and I got Casio to replace it. Then I had the same problem with my second NP 20 so I dug around for a way to fix it and I found the following advice on a site called FixYa. It worked instantly and I didn't risk ruining my battery.

I had the same problem as this.
what i did was...
i kept putting the battery on the charger then took it off as soon as the red light came on.
i did this about 6 times.
doing this puts a bit of charge in the battery each time before the charger starts to flash.
after the battery as got enough charge in it it can start to charge.
hope this helps.

This is a firmware program with the camera and it will need to be updated. The company will do this for $50

It happened to me. I fixed it by luck . Here is my way . fully charge the camera till the led turns green. "IMPORTANT" unplug the power of the charger first, then remove the camera from the cradle . Then I pressed power button, it worked.
Wish good luck to you too

How old is the battery? Keep in mind they aren't meant to last for more than a year or two, regardless of how often they're used. Generic replacements are actually inexpensive these days. Here's some from Amazon:

Casio batteries have a issue and are very weak you should not let it get below 5% when it is this low the camera will come on say battery is low and turn off. if it remains this or lower the battery can go out the good thing is you can get them really cheap off ebay.

My Casio EX-Z18 charger light keeps flashing red when i put the battery in to charge, it doesnt charge up therefore my camera doesny work. Can you hepl??

Casio says:

Red blinking light = defective battery

No flashing light = possible defective charger.

What you can do is send all your stuff into casio and they will test everything for you and see what they could replace for you.
