Something popped into my mind about this. What if ... Progo has not entirely
correctly decoded the Oly battery-camera
communications?
They claim greater capacity, yet deliver fewer shots. As I/we have assumed,
that could be because their capacity rating
is wrong - or Oly is using larger mAhs. :-)
It could also be because the battery communication with the camera isn't quite
right, and the camera is shutting down
for insufficient battery power when there is, in fact, adequate power for many
more shots.
As the camera does work with batteries that make no attempt to communicate with
it, it must have two means of
determining when a battery has run down. One would be based on intelligent
battery/camera communications, the other
presumably on simple battery voltage. Oly would have at least two incentives to
set that voltage high. They don't want
it to die 'dumbly' in the middle of shutter operation, image writing, etc. and
they would like to sell many of their own
batteries. (Why they price their own so high is a mystery to me. It they were
$30, I'd have two or three of them,
instead of the one Oly that came with the camera and three third party
batteries.)
As the Progos get about the same number of shots as un-decoded batteries, it's
possible the camera is shutting down
based on voltage alone, not camera comms. My Wasabi batteries do show full when
recharged and lower amounts left on the
camera battery indicator as they are used. That must be based on voltage alone,
and is impossible to distinguish without
a lot of testing from a smarter communication.
Is it possible that Progo has only decoded the battery/charger communications?
It's at least a theory that accounts for the apparent anomalies between rated
mAh capacity and no. of shots capacity.
Could also explain why more third party makers don't as yet sell 'decoded'
batteries, because they know they've not
cracked the comms completely.
I'm not saying one should not (or should) buy the Progos. They do, in fact
charge on the Oly charger, and deliver a lot
more shots for the $ than the Olys. Also, I only bought one, sans charger, so I
know nothing about the charger.
