zetor yes and no...the lowest fast charge setting is 200mah or .2amps. when it drops into trickle from fast charge it goes down to 50mah if the knob is set between 500mah/.5amp and 1amp, above 1amp and below 1.5amp it goes to .85mah trickle, 1.5 to 2amp takes the trickle to 100mah, below 500mah it offers no trickle. now I'm assuming(I know I shouldn't) that if no charge cycle is started it uses the same values for trickle, I have not put an amp meter on the charger after just plugging in a battery and NOT starting a charge cycle, I have checked the output and it is putting voltage to the battery even though the led is not glowing and no charge cycle has been started...so I assume it is charging at the trickle values... I use wall warts for first slow charging.

well I did some testing..flyingmonkey don't buy this charger,it WILL not slow charge like I assumed(I know better dammit) what I measured was feed back from the battery, not out put dumb.. dumb.. dumb.. sorry for leading you in the wrong direction. If you already went out a bought one I'll buy it from you. it is a good charger BUT it will only drop into trickle after a fast charge and 200Mah is to much for a good slow charge. I never slow charge my batteries except the first charge after that I always do a 1C or less fast charge. I've never had a pack that failed before I would throw it out.... when I buy a new battery I cycle it several times verify capacity and put a expiration date on it 2 years from the date of purchase ....batteries are cheap planes,motors and radio equipment are not. hell tell ya what I have 2 JR wall warts I hardly ever use, PM me your address I send ya one.


Again sorry for misleading you
