Are the opteka batteries chipped? Do they have the battery readout on the LCD?
Sorry, I do not know, But 2 Brand Cheapo Battery that I Have 4 Halcyon and 2 Wasabi, I do not think they have chip, because they will not tell me on my Battery LCD indicator ( ?).
Yes, my 2 Canon camera battries have the chips.
I bought an Opteka battery off amazon for $13. I will report back.
From my understanding - batteries that are chipped, will work functionally just like Canon batteries. The display will tell you battery remaining. You can charge them properly in the Canon charger.
Batteries that are not chipped, will not display battery life on the LCD. I think you can charge them in the canon charger but you also risk overcharging, because it does not have a chip to tell it when to stop charging? (This is all information I read online, so I do not know how accurate it may be. I am no electrical engineer)
In any case, $13 vs $45 for the canon battery seems like a pretty good deal if it offers the same functionality. I will report back when I get it.
