Battery Life for Rebel XT

Archived from groups: rec.photo.digital.slr-systems (More info?)

I have recently purchased a XT with a 17-85mm IS USM lens. I can take
about 1GB of JPEG on my SanDisk before the low battery lights come on?
Is this normal? Also, I realize with the low battery, I am able to shoot
but cannot perform proper metering( I press the shutter, it would not
beep, but would shoot instead). Sometime, turning the camera on and off
solve the problem. It's there a problem with my shutter release or os
this just normal if the battery is running low?


Thanks
CJ

I have the original Rebel and battery life, or the lack there of, is exactly
why I went out and bought the battery grip.

I just took 479 (2.63 gigs) RAW shots over 3 days and didn't have to charge
the batteries until the end of the second day and since I always have a
spare battery charged in reserve I just remove one of the low ones and
popped in the charged one and kept shooting. Both lenses used were Image
Stabilizer lenses (which draws power from the batteries.)

I believe the XT is suppose to get better battery life then my drebel but I
think I'd still suggest the grip. Besides after holding the XT I think its
size almost makes the grip a necessity. IMO it's toooo small.

What do you mean by that Sheldon ?

Does that mean that if I don't use it, it has more unused energy
available, only as long as I don't use it?

Precisely. Lithium-ion batteries behave much like the perpetual motion
machine I have invented. My invention offers the potential for perpetual
motion as long as it is not activated. Solicitation is not permitted on
this forum or I would provide you with the web link so you can purchase this
remarkable product.

On a more serious note, I will clarify my statement. For longest service
life, defined as number of equivalent image captures before end of service
life, a Lithium-ion battery offers more total captures if it is not fully
discharged before recharge. NIMH and NiCad batteries offer more total image
captures if they are fully depleted, but not to the point of reversal,
before recharge.

That is the published position of many of those who manufacture these
devices. Confirmation of this is only a click away on Google. My personal
observation, based on using rechargeable batteries since the very early
sixties, is that it is mostly BS.

The biggest problem I've noticed with NiCads is that if you leave them
discharged for too long they simply won't hold a charge again. I use NiCads
in my underwater camera, which only gets used once a year. I've had to bin
several sets of NiCads because, although the "fully charged" lamp lights,
the batteriesdischarge completely after a few shots.

I managed to shoot for a couple of hours (outdoor, no flash, no IS) without
the battery leaving full. I guess flash and IS really drain the battery.
