I always look at the low star reviews and decide from there. I received my batteries a few days ago and to be fair, the batteries did charge on my new Canon OEM charger and the Canon battery did fully charge on the OAproda charger. I’m still waiting for the OAproda battery to get to warning light level before trying a full charge on the Canon’s charger. The OAproda batteries already came charged, so I only did a refresh charge on the Canon’s charger. The Canon charger did show a red light indicating a charging status then a green light when fully charged. I did notice that the OAproda batteries were slightly thinner then the OEM battery. Which is good because the OEM fits really snug and I have to tap the camera to remove the battery. No problems with the OAproda batteries. It is not really loose but I don’t have any problems ejecting the battery. I don’t really know if the OEM battery is supposed to be that tight or not. The OAproda battery locks down properly and not loose.
