Battery capacity gauge

Hi,

The gauge introduced with the EM-1 M2 seems to be reasonably linear, which is a good thing. However the experience I have is that it when it reaches somewhere around 25-30% it's only a matter of time before the camera powers off. When using the 300/F4 with stabiliser activated, it occurs a bit earlier something like 35-40%. I have two batteries (Oly original), same behavior is shown for both.

Is there a way to calibrate the gauge? Or should I accept this as a "limitation"?

Re: Battery capacity gauge

Tord,
The gauge on mine seems to behave as expected down to levels <5% without shutting down - though my experience is limited to 12~100 and 40~150 Pro lenses on this camera.
Perhaps the (or your) 300 F4 draws a significantly heavier current when focussing?
It might also be a cold temperature related issue.

Hi,

I have that behavior with all lenses, and regardless of temperature.

Re: Battery capacity gauge

I've got 4 Olympus batteries and they all show ok down to 30 or 35% and then a few minutes later they are flashing orange. They continue to work but you have no way of telling how much is left so I normally change them at that point.

Re: Battery capacity gauge

At an Olympus experience day last year we were told they switch to red flashing with around 20% left in the tank.

After that I judge when to swap by what I’m doing: if there’s a chance of getting something really good that might need a lot of shooting (eg wildlife, when you might be sitting around for ages with nothing, then suddenly you’ll get a sighting that could go on for 10’) I’ll change right away.
However, if I’m doing something like street, where mostly there are only brief opportunities for exploiting any particular situation, I’ll hang on for quite a while.

Re: Battery capacity gauge

Can only add my battery indicator goes to flashing orange at approx 30%.

I always change battery at that point just in case the opportunity of a life time comes along, which sods law says is bound to happen..........

Re: Battery capacity gauge

Probably because it's not a true measure; it's based on a "function" of the remaining charge.
