i just bought a new hasselblad battery for my H3D.
and after charging i won't go over the 45% full. i did try the battery reset but still it shows only 45% full.
when i plug it in to the charger after some minutes it goes to tickle charging (blinking led) could it be a faulty battery?
Make sure you are holding down the flash and menu buttons simultaneously while inserting the battery grip. It should make a sort of whirring sound/beep when you insert it. If it doesn't, try it again.
If it still only shows 45%, then it could just be end of life. Have you tried a different charger? Do you know if the charger charges any other grips ok?
