10D diminishing battery performance?

For those out there still using 10Ds, I'm wondering if you've noticed reduced battery performance as time has gone by. When I first got the camera I was getting 300 or maybe even 400 shots per charge, but now it's about a third of this even on a brand new battery. Has anyone noticed something similar?

Do you mean "brand new" or " fully charged", because batterys can start to fail/fade after a couple of years.

??? You r kidding, right ? The battery must have been worn out or faulty from the very beginning. I expect my 1,5 yo Oly C765 to last 200-300 shots/charge. My 1yo 20D lasted ~1500 at first, and it's still good for ~750/charge now. Batteries wear out. Might be the time to replace the battery.

Batteries wear out, they're rated for 500-1000 charges I think. Get more from http://wwsw.terlingtek​.com , they're good quality and a great price.

The 10D, as I recall, was good for around 400 shots per charge (I'm going from memory, and mine is old), much less than the 20D which uses considerably less battery power. If a battery is giving considerably less than that, it is probably reaching the end of its useful life. Try a brand-new battery from a high-volume store (so that you know that the battery hasn't been on the shelf for 3 years).

Tim is absolutley correct. LiIon batteries only go 1000 charges and then need to be replaced. Sterlingtek is great for replacement batteries. At $12/ea it works well. Unfortunately Tim's fingers were working too fast. Here is the correct link:

I've bought 4 batteries from SterlingTek. 1 out of 4 was good. They sent me 2 replacements and the first one I put in the charger showed a full charge in about 20 seconds. The other one took about 25 minutes. They stand behind their products for a full year, but it gets to be a pain returning batteries all the time. Not to mention the fact that I have to wait until they arrive to take pictures. I ordered from another source for about $2.00 more. I will see if those will be any better

First I've ever heard of a problem with the Sterlingtek BP-511(A) replacement batteries. I own four and they all work fine. Many, many other folks on this board use them as well. I have had a problem with a canon charger which exhibited similar issues to what you state above (battery goes to "full charge" in a very short time) but it did that with Canon batteries. Bought a new charger and all was well.

also, LI-Ion batteries aren't happy when they've been greatly discharged (below about 2 volts per cell). they normally have internal protection to prevent them from doing so, as well as being overcharged (both conditions will basically kill the battery. once this happens, there is no type of conditioning that can save them. some cheapy generic batteries don't have this (you've heard of all those exploding nokia knock-off batteries in the news...). they are much better at handling cold than NiMH, but in very warm weather, they lose their charge must faster than the ~10% per month normally seen. this is what typically kills the battery - if it's warm and it hasn't been recharged in awhile, it can lose its charge below the 2 volts and voila! - battery with diminished capacity. one good way to prevent this is rotate your batteries and charge them once a month. there is no memory effect with LI-Ion batteries.

One thing to keep in mind:
The mAh Rating (Milliamp Hour) Rating
The higher the better.

Also, the battery charger that came with the 10D indicated full charge (LED going solid) when the battery was in fact 75% or better. Always charge based on time. I think the manual said 90 minutes was needed.

Of course the higher the mAh the longer it takes to charge, also the longer it will last.

A slow charge is easier and should extend the life of the battery VS. a fast charge.

Remember it is a chemical reaction, so heat is given off.

Cheers & Happy Shooting.

BTW, I'm so paranoid about running out of power I now have 5 batteries I travel with.

As mentioned,. this is totally normal for rechargeable batteries of all tyopes. Even Car batteries eventually die for good.

There demise is allways progressive.. not sudden.
Time for a new one. I've had good luck with Maha Powerex batts.

I have been using a 10D for about 18 months with no apparent reduction in the number of frames I am able to take. I usually get between 4000/450 per battery. I tend not to review a lot with the LCD and rarely use the built in flash. Still think this is a great camera apart from its slow start-up. Ian

I have 2 original Canon batteries and 4 SterlingTek batteries. Never had any problems with the SterlingTek batteries, and they cost only 1/4 of what the Canon batteries cost and also have a higher capacity (1800 mAh vs. 1350 mAh).

If you are storing batteries and you're not going to use them for some time, it's best to leave them empty - don't store them fully charged for longer periods of time.
