Battery Life

I'm interested in how many shots any of you are getting from cameras
in the "point & shoot" category, before the batteries die. It would
help if you told me whether you tend you take lots of pictures at the
same time (20-40), or just a few, store the camera, and take it out
again two weeks later.

While I have been able to do a couple hindered on one set of batteries
over a week or two. It can vary a great deal depending on the camera
resolution, flash time on and batteries.

When I first got my current digital, an Olympus, I used alkaline
batteries, very short life. Now with good rechargeable, it gives very good
life.

Which Olympus, and how many rechargables do you carry if you're away from AC
power?

I have a Toshiba PDR-4300 which is definitely a cheap P&S and considered a
bit of a battery hog (4 AA).

I get about 100 shots per charge regardless, but that may have more do to
with the fact that my 128Meg card holds just over 100 shots and I tend to
recharge the batteries everytime I clean out the card regardless of whether
they need it or not.

This is with 2100mA NiMH batteries. With NiCd I get about 50 pictures, 30
with Alkalines.
What is odd is that the NiMH don't have twice the mA of the NiCd.

ago, and I guess nobody responded because of the camera in question. So:

I've had varying results with a Kodak EasyShare camera (forget the exact
model, it's a 3.2MP)... two AAs will last anywhere from a week to a couple
months, sometimes running down to the "low" mark quickly and then continuing
to work there for a couple weeks. The NiMH battery that came with the
camera dock worked great at first but after a few months it won't hold a
charege.

The one thing that kill batteries fastest is using the LCD viewfinder,
especially if it's got a bright backlight. Flash is probably the next
greatest eater of batteries, but is a distant second to the LCD.

Hi Dominic,

We're frequently asked a similar question - it's down to several other
factors other than the mAh capacity. Some manufacturers are more honest
about their cell capacities than others ;-) But also, the internal
resistance of the cells may differ. NiCADs also suffer a memory effect, and
their chemistry is more easily disrupted by unwanted effects like
crystalline growth (this can be made worse with slow charging than fast
charging - although fast charging without adequate cooling can be
detrimental in other ways.)

It's also possible to have a large mAh capacity, with relatively speaking, a
poor energy capacity, because on the voltage - charge plot the voltage
profile is lower for one cell type than the other - even if the capacity is
the same.

I have certainly used 1800 mAh NiMH cells which far outperform '2300' mAh
NiMH cells in every way - basically because they are much better quality.

Kind Regards
