Didn't use my M for a while and recently started using it again, I've noticed something weird with my batteries.
I will fully charge them and they will only last 10minutes or so before the camera starts marking them dead.
Sometimes it will just last a long time like they actually aren't dead, other times it shuts off right away.
Anyone else experience this?
I have a new one on the way from Amazon to see if it's just the batteries, or if it's a body issue.
They're 7 years old and I didn't use them for about 2 years. Wondering if that killed them off, half are OE other are off brand.
