Question about Casio EXILIM ZOOM EX-Z70 Digital Camera
When I put my battery into the charger, red light on the charger flashing and my batter is not getting charge. I am using Rechargable Lithium Ion Battery NP-20 3.7V 700mAH.
Its pretty simple to fix. The lithium battery has just depolarized. Just buy a 9V battery.... put them end to end... the 9V and the lithium and touch the metal parts of them. hold for 20 seconds... if it doesn't work, lick the 9V to conduct the electricity better.. hold for 20 seconds and put directly on the charger... I just did this, and it is charging as we speak! good luck!

Use the 9V as Ricckk suggested in Solution#2 and it works like a charm (make sure you hold the 9V against the casio battery for about 20secs with the the right polarize i.e. + with + and - with - ). As well as the phone number Dobetta gave in Solution #4. I now have a spare. Thanks Ricckk and Dobetta.

I tried jump-starting my NP-20 with a 9V and it worked!! I just made 2 "wires" made out of aluminum foil and held them to the + and - of the 9V to the + and - of my camera battery and now I have the solid red light rather than the flashing red light. Thank you so much!!!

You are a genius! 9 volt battery kisses right up to the contacts.. Held it against my bad np-20 for 20 seconds.. and it is charging now without blinking red light. I also got a free one from Casio.. now i'll have a spare.

For those of us that dont have 9 volt batteries ...your not out of luck .... i had the same problem and after reading everyone post i was ready to grab my phone and call the hot line...but then i remembered what my chemistry teacher told me about ion reactions...so i put my battery in the freezer for about 10 minutes poped it in the chargering dock and booom the light stayed red and charged fully... now i dont have to wait a week,try it it'll work ^.^, the below freezing temperture slows down the chemical reaction bewteen ions and molecules generating enough enenrgy that the charger is able to charge it again ... i hope it worls for u guys

Your battery is locked up. I fixed mine by jumping with a 6v battery for 10 sec which got it to show some voltage. Charger then accepted it. Careful, I imagine to long a shock voltage could cause an explosion.....

Had the blinking light/no charge problem after about 6 months of light use as well. Called Casio at (800) 435-7732. They were very nice and sent me a free replacement battery that arrived in just a few days with no questions. That's the good news. The bad news is the replacement battery failed even quicker (about 2 months). I'll be on the phone again in the morning....

This may sound strange, but I slapped the battery down on the counter and the charger stopped flashing.

THANK YOU FOR THE 9V SOLUTION!!

When you put up the np20 and the 9volt against each other, do you put the positive terminal against the positive or negative terminal?

Much to my amusement after putting it in the freezer a couple of times and touching the 2 connectors of the battery to the nodes with no success and even emailing casio to express my disgust with my second battery dying
I decided to go all out .. so I left it in the freezer for 20 minutes and then got the tin foil out as suggested .. you wrap it around the connectors on a nine volt and then attatch to the two outer connectors on the battery itself ... the battery begins to heat up, and when its about to burn your hand off let go .. .and lo and behold my battery is no longer flashing so i presume its working now

Other people have been having this problem- I think it's common. They suggested calling Casio to have them send you a new one free of charge or go to Best Buy, Circuit City, etc. to buy a new battery.

Tried the freezer trick, didn't work for mine, called the 800 # They said we would have to buy a new battery. My husband had a universal AC adapter, , took 2 paper clips, set the adapter on 9volt, held for approx. 20 seconds, he saw a zap at first. And voila! It works! Thanks so much guys for the advice! We didn't have a 9 volt handy. But this worked too! Electronics class was good for something!

The 9vt battery trick didn't work at first, the metal around the 9v battery was in the way of connecting the camera battery and the 9v. So what we did was take 2 small metal objects (ie tweezers) and that helped the connection and the battery charger isn't blinking anymore :) Good ideas guys and gals!

The 9v suggestion worked perfect! Thanks a million...only took twenty seconds.

Casio America is full of you know what. I have only charged my NP-20 about 6 times and it failed. I called Casio for advice. They stated that the life span of the NP-20 is 1 to 5 years and pretty much said it was my tough luck. Rather spend $30 toward a different brand of camera than waste it on another Casio failure....

Very Cool 9 volt worked on my "old" battery and my bad replacement
Posted on Nov 02, 2009
I called Casio's support line at 1-800-435-7732 and they DID NOT replace my battery.
Nonetheless I tried the 9 volt trick and it worked.
Up yours CASIO!

Same issue here.
However, I called Casio's support line 1-800-435-7732 and they DID NOT replace my battery.
So I tried the 9 volt battery trick and it worked.
Up yours CASIO!

Thanks for the 6 and 9V battery idea!! You saves the day (I needed the camera for my daughter's party tonight!!!

Tried the freezer trick and the 9v battery trick...both did not work

I just found my camera, which had been stuck in the couch for about six months (I guess that's the downside of everything getting smaller). Same problem, no charge, the light blinks.
I called the number and they have a new battery on the way to me now. They did ask me a couple of questions, but even though I didn't have the answers (I don't remember exactly when or where I bought it), they still sent me a new one, free of charge, without me having to ask for it. It's really nice to deal with customer service that presumes the customer is always right. Casio gets points with me there.
I don't have a 9 Volt battery (what do they use those for anymore) so I put my current battery in the freezer for ten minutes. That didn't work unfortunately. I'm going to pick up a 9-Volt tonight and see what that does. Otherwise, at least that new battery is on its way.

I just got off the phone with Casio and as annoyed as I am that the battery went bad, they couldn't have been nicer. They were helpful, polite, no questions asked! I was on and off the phone in a matter of a couple minutes. I'm a little put out but knowing I don't have to pay for a new battery made my day. = )

Holy ****!!! The 9 volt battery trick really did work. I had to bend the negative side of the 9 volt out a bit so the connection was good but it really worked.
Posted on May 09, 2008
I did the 9V battery trick and the casio battery is now charging ok. Will also call Casio for a free one!
Posted on Mar 13, 2008
I called 1-800-435-7732 and they sent me a new battery free of charge. No questions asked. The initial battery lasted 7 months.
Posted on Feb 14, 2008
I called the 800 # and they gave me a replacement battery. It was pretty simple, just need the model and serial # of the camera.
Posted on Jan 27, 2008
I did the same. I contacted casio and they sent me a new battery free of charge.
