Don’t trust the indications on an NP F. As the capacity drops so does the output voltage. Under load the voltage drops further. When the output is sufficiently under volted the battery will shut down regardless of remaining capacity. Two bars could mean thirty minutes, could be five. Anton Bauer, and other, NP F970s would power my old camera monitor combo for 15 minutes then shut down with 75% left in the tank.
A lot of it comes down to input voltage. The newer Pocket cams have a wider input tolerance. The OG Pocket and micros for example would cut off at hard at 7V where the newer Pockets are stable down into 6V territory. Battery plates can exascerbate or mitigate the issue but it’s case by case. With the Micros folks were getting better results using 7.2V-12V plates because the plates were stable at lower voltage than the cams.
My new favs are the IDX iMicro98. They’re about 100g heavier than the Powerextra with 2-4x the capacity.
Good Luck
