LTC4060 slow charge

Dear,

I want to build NiMH/NiCd battery charger for 3 cells series connected. I found LTC4060 but it allows fast charging only. My battery pack of NiCd batteries is 3.6V/800mAh. I want to charge it with 80 mA current, but I have read that –∆V termination doesn't work very well when the charge current is less than 0.5C. Should I use external NTC and other full battery termination method in this case, or you can recommended some other solutions?

Best regards
