Surely this charger is at first sight more expensive than "traditional" or chargers Chargers with supposedly similar function. However, in my opinion, it is already having on the first battery that can be saved by the "reconditioning", paid for! In my case, I was a battery that could no longer be to restore as far as charging with a conventional charger, that they would have been able to make a starter, easily awaken within one day to life. Now back provides reliable service, as there had never been the accidental discharge. My conclusion, therefore, Highly Recommended!
