Re: LP-E6 vs LP-E6N vs LP-E6NH self discharge

After some days I needed some batteries so I had to use some. Here's the voltage drop. I kept only data after 8 days to have "relaxed" batteries.

It's quite clear,  a 18650 (no protection) has .001v drop in 8 days so about .09% voltage drop per month. More time is required to have a valid measurement, but we see self discharge is really low, much lower than what initial Li Ion battery that were close to 2 % a month.

The old NB-2L loss is about .60 % per month.  The internal circuits has an impact for sure. The LP-6EN is just over 2.8 % per month. Internal circuit has more impact.

Canon, please look at your battery pack internal protection circuits, it eats power !  Protection should be active when battery is used, not when stored.

Next test, having a battery in the freezer. Li Ion self discharge is much much lower in cold weather.  I'm quite sure that Canon battery pack voltage would continue to drop at the same rate as the culprit is the internal circuit and this circuit should not be slowed down  by cold temperature.
