Since my Camaro only in good weather comes to the street had a solution forth to safely restart even after a long service life still can. Initially, and on the advice of my workshop I was the battery trying simply disconnected (but which can cause various inconvenience, such as. Pressure Sensors want freshly calibrated ...) Then I researched online, and behold, many major car manufacturers offer Ctek Chargers in their range of accessories (modern cars have become proper power junkies !!!) without disconnecting but on any complex manipulations such as battery or expand to survive. Since I have also dispose over 2 diesel vehicles with correspondingly dimesionierter battery decided after studying the customer reviews for the MXS 10. Good Decision! Both diesel vehicles were first clamped and loaded (in sequence). Starter batteries are now ready for the winter. My Camaro hung time being about 8 days in the unit and allowed a dry weekend on the road :-) Everything Paletti. Now he hangs on again and I wait for sunny days. On the Function of the charger I can say this much: Operation ultralight, single-charging and maintenance programs run independently and reliably. Only the pulse charging function I could not even notice there's no cycle lasted longer than 10 days. Just like the weather, however, developed here, I'm going for a service life of 1-3 months :-(, will therefore still be able to report on the pulse charging. The supplied terminals, cables and connectors are well made and fits any vehicle ... unless you're dependent on an excess length. Just wonder if a device had 2 power levels less not been sufficient? At least hardly heated this charger is in continuous operation. Absolute 100% buy recommendation on my part. Update 28/11/2013: The battery is now connected to the charger for more than 10 days and the instrument has automatically switched to pulse charging. Everything funktionniert as it should.
