Best option for the charger and batteries? Leave it plugged in all the time or plug it in top the batteries off and unplug? Had a problem last week and mine started overcharging and blew some fuses and actually burnt some wires. Just glad I had it at the house and not my boat storage, I just happened to walk out and see it smoking. I now have a new NOCO Gen 2 and just curious as to opinions of others.

I top mine off and then unplug I usually will plug it up once or twice a week some guys leave plugged up all the time you can also put it on a timer as well.

I have the minn kota 4 bank I leave it plugged in for a coupe of days after I have fished all day and the plug it in the night before I go again of course if I am fishing multiple days in a row I plug it in every night.

If Im actually at the lake fishing I plug up everytime I come in and then again overnight.

You may have problems other than battery charger if it blew fuses on the boat. If nothing was turned on in the boat no current should flow from the batteries no matter what the voltsge. b

It blew the fuses on the charger which was a Minn Kota 4 bank, I was told ( by a Sheeter Dealer) that some of the older ones ( mine was an 08 )were know for this. Think I'll just top them off and have a 7 day time to come for a couple hours before the days I normally fish. Thanks guys.
