Hello to the group. I've got a question concerning my Nikon 5700 and
battery usage: with the OEM rechargeable battery, I could usually do
about 25 RAW images, before the indicator began moving and about 50
RAW images on a full charge, while the indicator slowly crept down.
Sometime back, I added the MB- E5700 base mounted battery pack. I had
initial problems with the NI-Mh batteries from the photo shop. I do
not recall their brand now. With a full charge, they would not power
up the camera. The shop replaced them with Camedia batteries by
Olympus, which worked well, with one problem. On a fresh charge, I
get about 2 RAW images, before the camera's battery indicator
immediately falls to 1/4 charge. I can still shoot about 50 more RAW
images, and have never run the batteries completely out, but the
indicator really doesn't give me any idea of the actual state of the
batteries. It doesn't seem to ever move from that 1/4 charge
position. This can be very disconcerting, as I never know when the
camera will just go dead. As I said, I have not fired until the
batteries ARE dead, and always carry a complete set (six) fully
charged spares, plus six non-rechargeables, just in case.

Does anybody have any experience with the MB-E5700? Does anybody have
any experience with the Camedia (Oly) rechargeables? Any thoughts on
battery brand, or charger brands? So far, this has not created any
problems, except for the fear, that I will suddenly run out of
"juice," kinda' like driving an automobile with a gas gauge
constantly stuck on 1/4 tank on a dark, lonely road.

Also, these exposures are without the built-in flash. When using
Nikon SB-80x, there seems to be no change in the indicator - still
1/4 battery life after 2 exposures and there it stays.

Thanks for your input,
Hunt

It's possible you have one of the earlier MB-E5700s. They had a defect
that rendered many rechargables useless. That may be contributing to the
shortcomings you note. Later models have no problem. I understand Nikon
will eventually exchange for a recent one if you persist.

A few days ago I did a couple dozen RAWs on a fully charged set of
Panasonic 2100MAh cells on a CP8700 and the little battery display still
shows "full".

Frank,

Thanks. Actually, I had been thinking about everything BUT the MB-E5700. I'll
stop by my camera shop on Wed. and talk to the salesman. Since I've been an
NPS member, since the 70's I suppose that I could go that route, however, NPS
ain't what it used to be. I appreciate the response, and will pursue a
replacement - one way, or the other. BTW, how did you get this info? I've done
a bunch of searching and have looked at every Nikon site for something to help
me, with NO LUCK, what so ever.

Appreciated,
Hunt
