These are genuine Canon cartridges, and work precisely as they're supposed to do. Incidentally they arrived in the proper Canon packaging (not re-packaged in a plain white box, which is what I got some time ago when I thought I'd ordered a Canon pack of inks).
This battery was bought as a spare for a Panasonic camera, so that when the original one runs out of charge there is a back-up available. Essential protection for any camera. The battery is a genuine Panasonic one, and it works exactly as it's supposed to do. So good.
