i have two 12 volt automobile batteries which are used in summer for my boat. i hooked up the said charger to them. i check the voltages on the batteries at least once a week. float voltages are approx. 13.4. i would like to see 13.8 volts, but this is acceptable. they also charge up the batteries fine after using them for a while. So far so good.

I purchased this product and when it came I was excited but what I found out was that it did not perform at all like it was described. I wouldn't recommend this to anyone. The seller was just OK because they did get it to me within a reasonable amount of time but the people that answered the phone didn't have a clue as to the product's capabilities.
