a charger that will not leave me !!!

my car does not drive a lot and every time I wanted to start my battery was flat! this charger saves my life! I did not putt three winter months and the battery was completely empty! from the connection it was flawless. he set forth to load, and several hours later it was done 100%. In addition, I am a woman and not really top of those things, a friend showed me how it works and it's very easy. He plugged the cables on terminals permanently and allowed him and the time of loading there is more to plug in the charger and plug it into the socket! from there, you press the star in the middle and chose the voltage 12 or 6! then it is he who begins the load and will detect if there are errors (by the yellow triangle)! what is must is it to stop and it only consumes almost nothing! I left a few days to see what it actually does and it's like fridges, it is triggered only when the battery down! it's great for me, por next winter because sometimes I do not roll the winter and suddenly I could plug it permanently charger on the battery to keep him in charge! it's something you have to have at home! plus it comes with a pair of crocs and more, we go to cazou troubleshoot other cars! a material which I could not do without
