Fast shipping, connection set supplied with quick connect system (clips, cigarette lighter socket and eyelets for permanent attachment to the battery). I bought it in order to "save" two 12 V lead gel batteries / start boosters acid, thanks to the function load pulses (desulphating ...) After a test of 48 hours on one of the 2 batteries, I find that it has regained the load: My previous tests with conventional chargers not allowed to light the lamp on the booster more than 5 seconds before it is emptied, while there I already want more than 2 minutes after only 48 hours desulphation. We must therefore connect and "forget" some weeks the charger and the battery to get to recover 100% of capacity. Note that my second battery was deeply discharged (5 v) and that the charger does not detect by following the instructions (see connect the battery and connect the charger to 220V). So I first plugged the first battery and the charger to 220V, the charger goes into "puls", then I unplug the first battery and the second part I quickly and there it works actually when you disconnect the the battery "smart" charger remains in the mode it was ^^
