Olympus battery charger flashes red when battery is inserted.

Another way I found was when this happens, to push the battery to the point the light will turn on, when it starts flashing slide it off then back on. Do this a few times so it charges a little, then you should be fine to leave it on.

I have an FE-230 and I have to insert the battery multiple times but it eventually will not blink and will charge.

I am trying to charge my battery, nothing is flashing they light is not on, Its the charger that came with it... is it charging??? I have no idea

If the charger is flashing red then the battery was allowed to fully discharge. You can either buy a new battery or force the charger to charge the battery. The way you do this is by applying a voltage across the charging terminals while inserting the battery. I opened the case of my charger and attached wires from a AAA battery to the corresponding wires attached to the charging deck (+ to red and - to black). Then I slipped the battery into the charger and plugged the charger into tho wall. The light should illuminate solid red (no flashing). Then immediately (and carefully) remove the wires from the charger.
