I have a number of vehicles that get little regular use, from farm equipment to collector cars. I have been looking for a charger like this for a long time. The charger mounted very neatly near the battery on one antique car and looks like it could have been factory installed. Easy to connect without having to move separate battery chargers on and off the shelf. I have had it about a month and if it continues to perform well, I plan on buying several more.
