What's your opinion of them?
I bought 4 from Amazon for my 30D. I figured that they were so much cheaper than the OEM that it was worth it even if only a couple worked. They all work just as well as the original and they were very cheap.
The trouble with asking a question like that is thay everyone who's ever had a problem with TP batteries will immediately take the chance to tell you all about it whereas those who have used them without problem may not bother to say so, so the answers you appear to get may be skewed.
That said, I've got one for my camera - I've had it a couple of years and it operate exactly the same as the original I use alongside it. The only real difference is that it was about a tenth of the cost!
I've had a similar experience with a mobile phone battery.
Generally, camera manufacturers don't make the batteries themselves but buy them in from the same factories that supply the TP ones and whack on an enormous mark up to take advantage of the people who must have a 'big name brand'.
If the camera manufacturer battery is just a few percent more then you may as well stick with that if it gives you peace of mind, but where the difference is significant why not try a TP bettery - you usually don't have that much to lose.
I've been using batteries from www.sterlingtek.com for a few years now. They were very cheap and they have more capacity than the Canon batteries. I wouldn't have a problem recommending them to anyone.
I had issues with my Nikon D200+ battery grip and 3rd party batteries. The 3rd part batteries did not communicate properly their actual remaining strength and if I let them go till completely drained, the shutter can pop and get stuck in the up position. Turning off the camera for a few seconds, and back on shows a 100% full battery... but it dies a few seconds later.
Changing batteries solves this issue.
I've since kinda decided to stick to the "real thing" and have no issues. I use the 3rd part batteries now more as emergency power than anything else. They do last just as long as the originals, but have the quirk I explained above. Since I know of this issue, its no biggie.
The circuitry that equipment uses to determine the charge state of lithium batteries requires that they be drained from time to time in order to recalibrate the determining mechanism.
If you start to alternate a new battery with an old one that cannot carry its original capacity you can confuse this mechanism.
It is not, however, a 'quirk' of either the original or replacement batteries (but rather the way these 'sensors' work) and is just as likely to occur if you use an old (many times drained) Nikon battery alongside a brand new one.
It is, however, something to bear ine mind if you do decide to get a new backup battery after using the original for some time.
It's not quite clear how sticking with Nikon batteries would change anything. I kinda suspect it's just a coincidence and that you've either stopped using your old battery(ies) of just happen to have used the batteries in such a sequence that the problem hasn't recurred.
See Here for some more information of discharge determination for Lithium cells.
I can charge these in my Canon Charger right?
If you mean third party equivalent batteries, then yes. I just charged one an hour or so back.
I have used Sterlingtek's batteries for years in my Canon 20D and have had zero issues. Folks that I have suggested sterlingtek to have also had great luck. I have not heard of a single issue with them yet.
I also use ones from sterlingtek.com - have four of them. Two of them is always in grip. No probs with any of them.
They charge in my Canon chargers - no problems.
4 of my 8 BP511's are sterlingtek and they last longer than the OEM Canon batteries.
That's been my experience also with batteries from Sterlingtek compared to the ones that came with the cameras.
