Eugene,

The safe way would be to use a 20-30 volt power supply with a series 
resistor to limit the current to 80 mA into the battery.  This is the 
standard "trickle charge" of C/10 where C is the battery ampere-hour 
capacity, in this case 800 mA.  16 hours will insure full charge, and if 
it sits on charge for a couple of days no harm will be done.

If you have a bench supply with variable current limit, you can use that 
directly without the resistor.
