Amazon.com: Black & Decker VEC1093DBD Smart Battery 40/20/10/4 Amp B April 06, 2012, 08:15:58 pm Yahoo Message Number: 129697Dale, I have had this (see link below) particular battery charger for several years. It was originally made by Victor and then by Black & Decker. I actually have one of each brand. Both have given me excellent service. I usually do the desulfate/equalize cycle at least once a year on all the batteries used on our ranch (about 12) and it does well extending the battery life. When you look at the Amazon page below for this unit, the specs doesn't show the desulfate function, but if you zoom in on the photo of the unit's front it is clearly shown as the battery recondition function. The battery first has to be fully charged before starting the desulfate cycle which takes 24-hours. It works on all three styles (Wet, Gel, & AGM) batteries. It is a bit pricey but it is well worth it!
