once upon a time, i had a little guest battery charger. it was a little fellow that only put out 10 amps and took a while to charge my batteries, but it did a great job and never cooked my batteries. my poor little fellow died so i decided to upgrade to a larger model. found a pro-mariner pro-sport 20plus which was twice the power of my little guest charger (2 banks at 10A each) and it even had "distributed" charging capabilities. On the box it even stated "3-stage" charging but on the unit itself it says "multi-stage" charging (which means 2-stage) - it seems they use the same box graphics on both the 2 and 3 bank models. My new improvement was cost effective and seemed to work great. I left the unit plugged in all the time just like my little guest unit. after about 6 trips out, I notice week batteries. corrosion was evident on the terminals even with the corrosion grease spray. the water levels in my batteries was each low. I even replaced a battery just to be sure. bought the acid level checker and checked each cell, and even added new acid to the cells of one of the batteries. cleaned up terminals, new corrosion grease, tight connections, and even a new 4-ga cable. 4 times out and low batteries. i'm giving up on the pro mariner prosport 20plus charger as i do not believe it is doing my batteries any good leaving it plugged in all the time. i'm posting this to warn others about the problems of which they may encounter with this unit as it has definately not performed up to my expectations and is a total waste money and good batteries. for a $100 more, i could upgrade to the "pro-tournament" model - nope, don't think so! I'm done with pro mariner products.
I'm off to buy another battery and hopefully a charger which will get the job done. I'm considereing another guest (2 bnk 10A each) or even a minn kota. anyone have any experience with the minn-kotas or heard anything good or bad?
thanks,
