HP-25: charging of battery pack

[Dr. Mabuse]

Dear HP Enthusiasts,

Maybe I miss that point, which has already been answered in other HP clasic threads ...:

Is there any problem / hazard to charge a HP-25 / HP-25C (Woodstock Model) by wall net power supply, when the calculator switch has been set in OFF position ?! Thanx for your feedback in advance ! I know about the problem, but I think it is only related to an Woodstock Model, which is in ON calculator position !



Kind regards from Germany,

Thomas alias Dr. Mabuse
