Motorola battery charger question

[DeanS]

Yes, I got one of those HK Motorola radios and it came with a battery charger that was originally 220 volts. There was a sticker over the 220 but it was in Chinese characters so I could not read it. Apparently it was converted to 110 volts and when I plug it into the wall socket the output it 16 volts. On the bottom there is something that might be a model number SX-2992 and 13.8 volts. On the front of the unit there are 3 light that read "Y-DI" "HS" and "SC". There is a switch on the back that read "H/L". When I first plug into the wall socket the red SC light in on. When I place the radio into the unit the yellow light turns on if the switch is in the L poistion. If the switch is in the H position when I place the radio into the unit the orange Y-DI light turns on. Does anyone recognize this battery charger? I'll be using this charger to charge a PMNN4001C 7.5 volt 1200Ah NiCd battery. Could someone give me an idea about how long it will take to fully charge this battery on the L setting. How about when it's on the H setting?
Thanks
