[Milsurplus] question about charging a PRC-68A battery

[W2HX]

Hi there.  I have a PRC-68A which works FB with Brooke's AA battery adapter.
I also acquired one of those NiCd rechargeable batteries for this radio.  It
says the following on it:

 

15 VOLTS 0.80AH AT 0.16A

 

I do not have a proper charger, per se, but can anyone tell me how I might
charge this battery with a DC power supply and an ammeter? What would the
correct set up lok like? Would I set the volts to whatever necessary to get
0.16A or something? Or set the voltage at something set?  The battery
currently has 5Vdc worth of charge and the battery is NOS, never used.

 

thanks
