Minolta lithium ion battery BC 200 charger has failed. Product reference 91-59041 Phihong DEC.

Depends on how much the battery is in use, and how much battery life is left.
If it's relatively new (3 years old) and fully empty, it could be full by 2 hours - 2 h 30 min. If it gets really hot before that time, it's full by then.

Lithium Ion batteries don't charge the same way ni-cads or ni-mh do. You need a lithium ion specific charger to charge them. (Some chargers do multiple types.)
