Very convenient to attach a Ctek charger witout having to remove a bunch of stuff to access the battery.

Anyhow, my question for those of you that might have one, do you find that the yellow and red lights come on far too soon for the state of charge.

My 6 month old Dekka AGM battery always measures at least 12.5 volts with a voltmeter. At that level, the indicator is already in the yellow.

 

i dont have this ctek, but i do the other ctek charger. I hook it up mainly during the winter months when its parked outside. Run the charger once a month. Takes about 2 hrs to go from charging to green full battery icon on the charger.
