Need a bit of advice please on my battery/charger situation.
When charging my 2 batteries [40d], the charger goes through all the light blinking i.e. 1 blink, 2 blinks, 3 blinks then continuous.
It does this in about 20mins which seems a bit quick and then when I put them in the camera they display as full for a minute then drop to 'low'.
I'm wondering if anybody knows what is happening? I'm thinking it's the charger not charging properly since this is happening on both batteries but they are the same age and getting on bit [6 years], maybe they lost their charge?
I can't test them out on anyone else's gear because they have different batteries for their bodies.
Anyway thanks in advance
