20d battery life?

Hi all! Just wondering how long the average battery charge last's on your 20d.Only reason I am asking is because I picked my 20d on Thursday and had to charge it on Saturday(when i put the battery on the charger,if you go by the manual it said it was between 50-75% charged?).Got a 2gb card with only 18 pics I kept but have been using it to get use to it.Up to now i have been shooting with and eos3 and an ellan 7n.Is this normal?Best regards to all...GORDO..

Our doesn't last too long: the batteries on 5D and 1D-series definitely hold up better.

Hmm, what can I say, don't judge a new battery upon a first charge.
Between 50-75% ?? My manual says 2 blinks for 50% and 3 blinks for 75%, so what "between" should be, 2.5 blinks?
I shoot occasionally and moderatedly, so a charge may last even a month for me.

Shot a wedding with my 20D two weeks ago and was quite surprised - 300+ images, lots with an IS lens and no new battery needed.

I have had batteries that go dead quickly - a matter of 10's of shots -- they do have a lifetime -- my expectation on a good battery fully charged is that it will last all day -- typically hundreds of shots. The amount of time you chimp affects this but in general mine last a good amount of time. Dennis

Does that mean you're a heavy chimper? If so, that's a big juice drainer.

I was out shooting yesterday and using IS, some pup-up flash for fil, and it was still reading full when I got home after about 200 shots. This is a 1 1/2 year old battery.

Similar performance with a new (charged once) Sterlintek 2000maH battery.

I have shot for two days on a single charge with over 500 images, it still indicated full charge...

I've always found mine to be very good. Based on my experience with my old fuji, I bought 5 extra batteries for the 20D when I got it, as I can be blazing away all day at some events. Never needed them all, one is all I need to carry as a spare (although I carry more 'just in case'). I can shoot for most of a day on one battery, racking up 1,500 + shots. I did manage 2,000 + in about two hours once and the battery indicator was still showing full.

It should be noted that I don't do a lot of chimping, just an occasional glance at the histogram to check my settings, nor do I have the camera set to show images on the LCD as they are shot, there is no flash used at these events, but I do use IS lenses (generally the 100-400L). Also, most of my batteries are the cheap non-branded ones which are rated at 1500mAh, rather than the Canon ones which are only 1300mAh, however I haven't noticed the Canons being significantly shorter lasting.

I tend to put a fully charged battery in at the start of the day and only need to change (if at all) towards the end of the event.

I suspect that the amount of time the camera is switched on is more significant than the actual number of images taken in that time.

With the grip I forget the batteries need to be recharged. Maybe replace the two with fresh batteries every month or so using the 20D a lot, 600+ clicks. The 5D is so good with power, I don't change those batteries much more than the 20D with the grip.

I very excellent battery life with my 20D. I use a Grip + 2 canon brand batts. and i get a solid 900-1000 shots when using a lens w/o IS.

I also take a few hundred shots and store my camera for a few weeks and I am able to pull it out 2-3 weeks later and take another few hundred shots w/o ever seeing low battery. I put my battries throught cycles when I first got them, to help the break in. Full charge / discharge.

Really don't have a clue other than it's in the upper hundreds of shots. I shoot with and without flash, chimp a little, one lens is IS. Just get a card reader and use it to download as if you do it through the camera the battery will drain quicker.

After coming from a P&S with it's constant LCD, I'm thrilled with my battery life. The stock Canon gets me many hundreds of shots.

Thanks to all for your reply's.Now if i only knew what chimping was?All the best.GORDO.

I get over 300 shots also. Usually about a day of toying around for me. Sometimes a bit less if I am very actively shooting with the camera. I also picked up two batteries from Sterlintek and get around the same time with them. I have three batteries now and I numbered them just so I know which is which. I go through them in order so I know that each one has had about the same amount of use. I would suggest grabbing the double pack from Sterlintek anyway since it's such a great deal. Then with them all fully charged you should get at least a couple days of full fun.
