LP-E6 Battery Tester. Is there such a thing?

I don't know if this technique will be of use to you, but I keep charged batteries in those orange plastic protection things that they come with until I load them into the camera. I don't put the protectors back on until the battery has been recharged. It works for me.

Yeah, that's what I've started trying to do. Probably the best approach, but requires more discipline than my usual unfocused nature. The problem with photography is that the merger of technology and creativity means that the right and left brains are constantly at war with one another and my right brain usually kicks my left brain's butt.

I keep the plastic covers on my batteries when they are not in the cameras. I use a 1dx and a 1d4 and simply turn the securing screw 90 degrees so that it is not flush with the battery after use, and then turn it flush after charging. If I were to use any LP-E6 batteries I would use this method…

Flipping the way you attach the cover reveals either a bright blue battery shape or a black/gray battery shape. I hope this helps.

I use the same method for the LP-E6 battery as described.

However, most is solved the last year by having 2 places in my backpack. One for the loaded, the other for the unloaded batteries (LP-6E, 1Dx, AA, AAA). So when arriving I home, no need to think, just empty the unload part the backpack and place them all on the chargers.
