Battery troubles with my G2

I bought my G2 used about 2 years ago from a large dealer here in Canada. As I'm sure you all know the G2 uses the BP-511 LiIon battery. Well the Canon batterytI got with the camera worked great for about 8 months before refusing to hold a charge. I researched buying another Canon branded BP-511 but here in Canada they sell for $120 CAN dollars. I figured that's nuts, so ended up finding a Chinese knockoff with more capacity and a price tag of about $20 CAN. It's been 1 more year now and now that new battery is at the end of its life too. I use my camera a lot and charge it frequently because of that. The stories I read about 400 shots from a single charge are foreign to me. I've never been able to get anywhere near that sort of battery life. Would it be wise for me to find maybe a CA-560 power adaptor and use that instead? 95% of my photography is product shots or indoor photography. I am normally close to an outlet. I just wonder if its more economical to stop buying replacement batteries and just be able to plug the damn thing in.

Thanks and very nice forum you have here

Mike, go to this thread (https://photography-on-the.net/forum/showthre​ad.php?t=46192) and see if anything is of help.

I to had a similar problem and using the battery as much as possible and repeated discharge brough it back. Like you I charged before ever reaching a deep discharge. They say lithium batteries don't have a memory effect like NiCads but my experience is the behave like they do!

Thanks John. All I did was remove the battery, charge it for maybe an hour ( orange light was still flashing not even solid yet) and when I removed the charger the battery reading was full. I must have shot 30 or 40 flash pics and the battery meter never moved and the low battery warning never popped up. You are correct, there is nothing wrong with this battery.
