The Rexton charger 3g-04 is a device used to charge the batteries in Rexton hearing aids. If the charger is flashing red, it could indicate that there is a problem with the charger or the hearing aid battery.
Some possible causes of a flashing red light on the Rexton charger 3g-04 include:

1. The battery is not properly seated in the charger: Make sure that the battery is fully inserted into the charger and is making good contact.
2. The battery is damaged or faulty: If the battery is damaged or has malfunctioned, it may not charge properly.
3. The charger is damaged or faulty: If the charger is damaged or has malfunctioned, it may not charge the battery properly.

Internal circuit fault to the charger. It will be best to buy a new one.

In that case, you are not using the correct charger for the battery, which could cause it to explode.

That don't work plus been calling tech support for the last three days

Hi,
The red and green flashing lights indicates that there is an internal problem in the battery...remove and retry.... if it persists then the battery will need to be replaced...

three things to try.. reverse polarity on the charger (turn the plug around), clean the copper contacts on the battery and charger, get a new battery

I recently purchased the same exact charger for the same exact battery....I had to slide the battery in backwards to align the positive and negative and then it should charge properly. If you slide it in the other way which seems to be the front side of the battery the light will automatically appear green same as if no battery was in the charger. This is because its not aligned to the positive and negative from the battery to the charger. Best Wishes!

Positive to positive is correct. Red is charging green is done.

The cradle is defective.  Casio replaced the first one of mine for free then they told me to sit and spin when the second one broke 8 months later.  I had only used the camera ~ 10 times.  So, I went to a big box electonic store (Best Buy) and bought a Digipower travel charger.  It charged the battery up just fine.  I also bought a Dynex Memory Card Reader/Writer to transfer the photos to  my computer.  Good luck.  The defective cradle is a known problem that Casio is refusing to correct.
