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

We don’t have any NHes but I can assure you all our batteries discharge at a fair rate of knots. Between two locations we probably have 50 LP-E6s and unless they are all used routinely they will discharge. And this happens to Canon and third party batteries.

But here’s the kicker, even if you think they aren’t discharged - they are! What happens is that the discharge internally does not seem to change the output voltage, which is mapped to discharge. So the battery internally is discharging, but when you reinsert the battery it initially registers a higher voltage than the one in the discharge map. So you think the battery is higher than it really is.

Over the next hour the voltage drops rapidly and you watch the bars disappear.

The winter is usually a big problem, we may not shoot for several weeks, when we get going again everyone is taking twice the number of spares to make sure they get through day, and then we start cycling through the batteries again. It can take 3-4 cycles before the battery fully recovers.
