I have been on love with my Olympus e-20n since the day I bought it. Yes, it's only 5 mega-pixel but the SLR design and full manual functions out weigh the limited resolution. I was very disappointed when I tried to buy a replacement high capacity battery and Lithium Polymer 8400ah battery was not only discontinued but totally not available (except for some used ones on Ebay and I'm just not brave enough to buy a used battery)
So crafting a replacement became my Memorial Day Weekend project. One quick trip to Fry's Electronics later and I had the solution. A 6-cell AA battery holder, 6ea AA NiMH 2600ah rechangeables and a 9-volt battery clip with pig tail is all I needed.
Crack open the external battery add-on (looks like a power winder on a 35mm SLR) 4-screws on the botton, one inside the battery well and 2 under the rubber hand grip. Locate the battery connector and un-screw the RED and BLACK prime power leads from each side. Cover the connector with electric tape or an insulated cover, your done with it, forever.
Solder the pigtail 9-volt battery clip to the RED and BLACK leads (red to red and black to black, duh!). Extend the 9v battery clip outside the case and re-assemble the case.
The 6 AA-cell battery holder will fit nicely into the battery door cup and if you pack the vacant space in the battery well with sponge or an old gym sock the battery will not slide around.
Fill the AA battery holder with the rechargeable batteries you have freshly re-charged and hook up the 9v clip. Thats it, new life for the my old companion.
Aye, jpierre's solution was right on the money. Touch the positive (+) end of the 9v battery to the positive (+) end of the camera battery. Leave them touching for a few seconds (10 seconds should be more than sufficient). Seems these lithium-ion batteries are subject to a 'digital memory.' Subjecting it to a volt surge almost three times higher seems to clear it.

ok my friends is very easy and let me tell you something wokrs.just take the battery of the camera and any transformer with output 9v put one wire on the (+)and another on the(-) after take you battery and put (+)--(+) and (-) for just 3 o 4 seconds that will reactivate the battery and put it back to the charger ,,,i tried my self and works good luck
This problem is known. There is a way to fix it. The fact that it blinks on and off means that the battery is completely out of energy. Thus, the charger doesn't "recognize" the battery.
To fix the problem, you need to give some energy to the battery. What I usually do is that I use a 9V battery (or any other source of power) and I link + and - of both the Casio battery and the 9V battery. You can use a paperclip as a link (you will use 2 paperclips, 1 between minuses and 1 between pluses). Do that for 2 minutes and then charge your battery as usual. It should work !
I HAVE A RED BLINKING LIGHT, AS WELL. FIRST, I CALLED STAPLES, BECAUSE OF THE EXTENDED WARRANTY I PURCHASED. AFTER A 10 MINUTE TUG OF WAR, WITH AN AUTOMATED OPERATOR, I WAS FINALLY CONNECTED TO A HUMAN. I WAS TOLD THAT IT WAS A BATTERY ISSUE AND IT WAS NOT COVERED ( BIG SURPRISE ). SO, I JUST CALLED CASIO @ 1-800-435-7732. A LIVE OPERATOR ( BONNIE ) CAME ON THE LINE WITHIN 2 MINUTES. SHE ASKED ME THE MODEL NO. ( EX-Z75 ) AND PURCHASE DATE ( CHRISTMAS '07 )...SHE SAID THAT IT HAS BECOME AN ONGOING PROBLEM WITH THE LITHIUM BATTERY. A NEW REPLACEMENT BATTERY WILL BE SENT OUT, TOTAL FREE OF CHARGE WITHIN 5-7 DAYS! NO PROOF OF PURCHASE WAS REQUIRED. CASIO IS A PLEASANT SURPRISE IN TODAYS CORPORATE WORLD.
WHILE POSTING THIS, I THOUGHT I WOULD GIVE THE 9 VOLT BATTERY TRICK A TRY. AGAIN, I WAS PLEASANTLY SURPRISED...IT WORKS! :)
known issue, battery needs to be 'shocked" back to life. Here's the fix:
"Hi,I just found a soultion on another website and it appears to have worked for me.Apparently the battery loses it memory when fully discharged,to fix this take a 9v battery and place the terminals + to + and - to - with the camera battery for 30 seconds or so then put the battery back in the camera and charge as normal.I just did this and it seems to be charging and the red light is solid.hope this helps."
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!
A red flashing light does NOT mean it charging. THat means you have a defective battery. Call tech support and tell them that you have a defective battery and they may be able to get a replacement for you.
