The light stays red when charging. will not take

Do the batteries charge? Are they charged? The green indicator normally is the status signal that the battery is charged and the red indicates that the battery needs charging or is charging. If you plug in a charged battery, some chargers will flash red momentarily then go out. This is an indication that the charger checked the battery (red light) and if the charge is good, the red light will go out. I hope this helps you.

It could not be making good contact with the charger.Check the contacts on the unit and the charger-sometimes the connectors get bent or something is stopping the circuit to complete. Wiggle the device while it is on charge and try to make the light stay on.

CHANGE CABLES TO BATTERY

Try removing the battery, hold the start button for 10 seconds, then reinsert the battery.

Hi.

The little red light means your battery requires charging.

Plug in the charger and allow it to charge.
It should change colour to orange when it has over 15% charge in it and then turns green when it is 90% charged.

If it still stays red dispite being fully charged. Try removing the battery for a few seconds and then replace it again.

I hope this helps.
If your phone is fully charged and it still has a red light, then take it back to the shop you acquired it and get a replacement.
It means you have a hardware fault.

when red light goes off bluetooth is no longer charging

I had the same problem some time ago. I called Casio Live Support number and they sent me a new battery free of charge that works.

According to the manual, the red light comes on while charging when the battery does not yet have enough charge to sustain a 3-5 minute shave. The green light stays on steady while the razor is charging, and blinks when it is fully charged. If your battery life is short, they might need to be changed.

read the owners hand book
normally the lights stay red until the battery is charged then it goes green
if the power is cut or if you switch the point off with the charger still in it and do not remove the charged battery , the battery will discharge through the charger

Wait, how long have you waited for it to charge? It's supposed to stay red until over 80% charge, then switch to yellow. When it is fully charged, it goes to green. When you mean it stays red when plugged in, have you waited the 2 hours?
