I have had my cam (and battery) for about 5 months, lately the battery seems to be depleeting very quickly and then does not seem to charge properly. Does anyone know how long they should last? Or is there any ideas how to increase battery life?
p.s probably taken 25,000 shots (tho i do have a spare battery i use some too)

| I too have a 300D and just recently bought an additional battery on ebay for 11.99. I don't know how long they last; however, I have had mine for 6 months and countless number of pics. My other battery is still running strong but not lasting quite as long as it did when I first bought it. The battery I bought on ebay was brand new and I am pleased with that one. |

I have had my D60 for about 18 months and have been balancing between two batteries all that time (I think I just hit 20,000 shutter actuations or so). I am just now starting to notice that at least one of them is not holding it's charge like it used to. Not sure if that is typical or not.
Edit: Make that about 15 months, now that I actually math it out.

The Canon BP-511's are lithium Ion batteries.
They do not suffer from a memory effect - i.e, you can recharge then whenever you like, you don't have to wait until fully drained. In fact, draining them completely decreases the useful life - its better to recharge a half used Lith-Ion battery than to drain it completely.
They have a two to three year lifespan, from the date of manufacture, so if it has been on the shelf for a long time before you bought it, there goes a significant part of the useful life. It thus isn't a good idea to buy several now and keep some as spares that aren't used.
They should in general be kept cool (i.e., leaving them in a car will reduce their lifespan.
Also, you shouldn't store them fully charged for long periods of time, as this again stresses the battery more.
Typically they can support 300-400 charge/ discharge cycles before significant loss in performance. After that they go down hill rapidly.

I thought I had read 100 recharges (but don't remember where), and about 300-400 shots per charge (which is on Canon's store listing). But even at 400 recharges, I'd say 25,000 shots before wearing out is pretty good!
One thing I never have seen anything about: Like Gordon said, the lithium ion batteries don't suffer from memory and can be recharged at any time. But say you always recharge when the battery's only half empty. Would you still only get 300-400 recharges, and thus only half the battery life? Or would it let you recharge more times, say 600-800? I don't always worry about draining mine all the way, but I try to most of the time, just in case its the former.
Edit: Doh, should have read more, skimmed less. I see you more or less answered that question...

Gordon you are a wealth of useful information! I was wondering about those very points and was actually going to look it up (the owners manual gives minimal info) but you've saved me the trouble. Thanks.
