NiMH discharge rate too high?

I have a 2600 NiMH Camelion Battery and I had charged it to full a week ago. Today I put the battery in the camera and immediately it showed low battery. I would like to know if NiMH batteries discharge so quickly??
 
Did you charge them on a regular charger meat for NiCds(the tranformer based ones )?

If yes, the charger is the culprit, those chargers never charge hi capacity NiMHs properly
 
though its written Ni-MH charger the weight and the input voltage is 230v so i think its transformer based. So are the batteries dead then???
 
Yes, the 230V input is a dead giveaway-

Good news- the batteries arent dead (hopefully)

Bad news- You need to get a MOSFET based charger :P
 
what do u mean hopefully they arent dead???

It doesnt hold charge for more than a week or less I should say.

Is this wording say that its a MOSFET charger?

100VAC to 240VAC 60/50Hz worldwide
 
coz they aren't getting charged properly by your charger...EVen if you put them in the camera right after a charge, do they run as much as youd expect from 2300mAH cells...

I had the exact problem....just switched to a good quakllity charger, and poof, the problem vanished :)
 
just opened the charger and saw there was a small transformer but there was also an electronic circuit. I am a bit confused now.
 
that electronic circuit is nothing but 4 diodes in a bridge config (AC- DC conversion) and a filter capacitor :P
 
possibly a voltage regulator? :confused:

AFAIK, Transformer based chargers cannot handle the trickle charging method that NiMHs need to deliver the best pperformance...
