this happens only with my epson batteries...

i place the battery in the charger, the red light goes on and then after a few hours the red light starts to blink.
after removing the battery, the red light continues to blink until i unplug it.

this does not happen with generic batteries.

i have 2 chargers and it happens with both of them.

is this normal behaviour for epson chargers and epson batteries?

happens to my charger for BLS-1 batteries (original and replacements) as well as for the epson's (also both original and off-brand replacements), too. looks like there is a little bit too much of "intelligence" in the charger?

anyway, as long as the charging works right (and it does), i don't bother.

Got this with a Canon charger and a faulty battery once. Are you sure your Epson batteries are OK?

Do you unplug the charger when not in use?
I´ve camerachargers from Epson, from Leica and from Nikon and all are making some noise when pluged in and not in use, that means somewhat is still going on. Just a better feeling, using one cord and I never noticed the blinking error.

I usually charge my batteries when I;m doing other things so they are not near me, but I never noticed that before. The red light comes on when they charge and off when they are done, no blinking..
 
Have had 4 of these, and only get a blinking red when battery is not inserted right - I just remove the battery and reinsert it until red light is solid. The light goes out and stays out after battery is charged.

All are Epson batteries, except one Fuji brand. 2 came with RD1 originals, and 2 came with RD1s models, but they all look the same.
 
should have worded differently

should have worded differently

What I mean is that sometimes I'll insert the battery (contacts inwards) and the red light will just blink immediately, so I remove it, and reinsert it and either on the 2nd or 3rd insertion, the red light just stays solid until charged.

pretty hard to insert incorrectly, they only go in one way.
at least, in the oem charger.

has anyone tried cleaning their battery contacts (maybe charger too) with a q-tip and some weak alcohol solution?
 
I use now this set:

Details can be seen in my blog entry about my generic EPSON batteries.

The charger starts to charge with the orange LED constantly on and indicates a full charge by switching the LED off.
My German engineer brain indicates, it would be better, to have one LED blinking during charge and constantly on, when the charge is full, to indicate a fully working LED and charger as well.
You can't have all for the very, very low price on these Chinese chargers and batteries.

Is there some kind of battery status indication going on with your charger Joe? Blinking code = battery fail, need calibration, etc…
 
your observations seem to indicate that the epson batteries are no longer at their best capacity. this should be normal, looking at the (assumed) age of more than 2 years. since they are Li-ion batteries, they will degrade after some time until they are finally no longer of good use. this degradation period is not related to the use of the battery. it starts immediately after production. most Li-ion batteries i used were "finished" latest after 4 years.
whether or not the degradation process is related to your blinking LED issue i cannot tell.

my experience with different chargers/batteries is, don't let the blinking light confuse you. check the temperature of the batteries while charging - if they don't get extremely warm, and as long as they keep their charge for reasonable time, use them. if they overheat, or discharge too quickly, replace them.

in rare cases, malfunction of the charger has been observed, usually resulting in destroying all batteries that are charged - this seems not to be the case, as your replacement batteries are well intact, while being charged in the same device.
