I am having really strange behavior on my brand new (B&H bundled) grip with K-3
(no battery in camera body)
Grip with 6 fresh alkaline AAs (tested 1.4v, 5a each) has shown 1 bar of battery left
Inserting the holder with main pentax battery into the grip shows 100%
(with main battery in the body and AAs in grip, grip-first setting)
Playing with battery settings (auto to alkaline and auto detect, turning camera on and off) is showing: battery depleted, one bar, of 100% randomly
I have upgraded to firmware 1.03, same behavior
This could be
1) defective voltage sensor (but is it not the same sensor used when main battery is in the grip??)
2) software bug
3) bad contact (maybe)
I see some issues with grip power posted, but not quite the same. Is anybody having the same issue?
Thanks,
Julian
Your description implies the batteries cannot sustain a reasonable voltage under load which is quite common fro Alkaline batteries.
Alkalones are really a stop gap when the chioce is nothing or alkalines , You will never get reasonable run times out of them as they will faill early even though potentially only partially discharged.
It's an issue with alkaline technolgy and hi drain not a camera issue.
