Bought a refurb M200 from Canon. Unlike the camera and lens, the battery looks refurb (more likely used). Marks on the glossy black portions and no protective cover on the battery terminal.
Did you happen to notice if there were any marks on the battery terminals before you put it into your camera or charger? The lack of a plastic battery cover in the package does not really mean anything.
I charged the battery fully at 7PM last night and stored it outside of the camera. This morning at 8am it required an additional 8-10mins to fully charge.
That is not necessarily unusual. Lithium batteries don't really like sitting at 100% and will drop a little. Also, going from 95% to 100% is harder than going from 80% to 95%. Taking an additional 8-10 minutes to fully charge again is hard to quantify. In that time did the battery charge from 97% to 100% or was it 75% to 100%?
Battery was stored outside of the camera in the camera bag. Ambient room temp around 63-65 degrees Fahrenheit.
In usage terms: I got the camera last Tuesday. So a week since last fully charged. I took 20 pics (1 with flash on to test) and about 1hr setting up (screen on) in that span. Battery yesterday was around 50% based on the camera battery bar.
Dropping to 50% after an hour of screen use sounds completely normal. Pretty much everyone with a new camera sees something similar for the same reasons. Spending hours scrolling menus and playing with settings sucks up a lot of power.
is all this normal? Thank you.
Everything sounds relatively normal. If by chance the battery is degraded, it is not dramatically so. Try to run the battery down to 50% a few times and get some more charge cycles on the battery. After that, put a charged battery in the camera and leave it for a few days to a week. Dropping one bar after sitting for a while is normal. Dropping to 50% in a week would be cause for concern.
Unfortunately I didn't check for marks on the battery terminals. I saw marks on the glossy black parts of the battery and immediately assumed it was used.
I can't answer whether it was charging from 97% to 100% or 75% to 100%. I don't think there is a way to display an accurate battery percentage? Camera doesn't show percentage unless I missed it.
Today I took 215 shots over a 4hr period and that dropped it down to 2 bars. WiF and bluetooth off. Single shot, no servo.
I think 215 shots from LP-E12 is actually rather good, especially at single shot.
I guess it's not safe to say 2 bars is 50% because the manual doesn't go by percentage instead saying:
Full bars: Battery level is sufficient.
2 bars: Battery level is low, but the camera
can still be used.
1 bar: Battery will be exhausted soon.

No bars: Charge the battery.

Fujifilm's X-H2 is a high-resolution stills and video camera, that sits alongside the high-speed X-H2S at the pinnacle of the company's range of X-mount APS-C mirrorless cameras. We dug into what it does and what it means.
