Query: Does NOT charge car/truck batteries

This unit only maintains car/truck batteries. The charging time chart in the description is not the same as in the box. The chart in the description lists charge times for car batteries; The chart in the included directions shows 'maintain only' for any car/truck batteries 200 - 1000CCA.The manufacturer should be more clear about this in their description. It kind of implies that it will charge car batteries. It should state "charges some smaller 12V batteries" not "automatic charging accessory for use with everything from smaller batteries designed for motorcycles, tractors and mowers, to standard car / truck batteries and marine / deep cycle batteries."
