hey to you who may know this...

im experiencing some difficulties with the battery life indicator,where after i fully recharge the battery,the indicator display show a full bar.. however after took couple of photos,then it went to 1 bar..from what i read,a fully charge battery can go up to 500 pic..

the battery itself is the problem or wat?btw i got spare and the same thing happen as well..

p/s i been using the battery/spare for 2 years now...
