How long do you guys find it takes to charge fully depleted batteries? (The large ones)

fully depleted BP-827 is about three hours, but I never timed that, as soon as the light on the charger goes gren;

thanks Buba, I'm color blind and cannot tell when the charge is done. I'ts weird I know. Thanks!

I am relieved, I had no idea they charged so quickly!

Would using a red (or green ) gel or filter to view the light help tell you the state of the light?

the nominal charge time are listed in the owner manual.

Not a bad idea Don, thanks.
