Hi I've got a pair of Sony A7iii and I'm wondering about battery charging.
I charge my batteries with a Hahnel Pro Cube 2 charger. Today I was charging batteries for a job tomorrow and when the batteries said they were at 100% I popped one into one of them into one of the bodies and turned the camera on. I spotted that the battery charge level only said 90%. Odd given that the Hahnel Pro Cube said 100%.
(This is an original Sony battery not an after market extra.)
I took the battery out and popped it back in the Pro Cube. Which immediately said it was at 100%.
Ok... maybe the battery is failing?! That's fine. I've got backups. But it confused me.
I put the battery back in the camera and attached a USB cable to charge it "in camera". When the LED light went out to indicate the battery was fully charged I turned the camera on again and it indicated a charge of 95% on that battery.
I can accept that the battery might be failing. I'm just confused why the Hahnel Pro Cube would say 100% but the camera only say 90% (and 95% after charging until LED goes out "in camera").
Any thoughts?
