Battery Tender

[MSM1970]

Any thoughts on leaving an on board charger hooked up 100% of the time, In other words leave the ring terminals permanently connected , and just plugging the unit in , when the boat is not in use .

That is what I was saying some members do but I don't. My on board charger is always connected to my batteries, but I just plug it in when I get home, then leave it plugged in for one day. Not sure if Bearlakefishguy will see this or not but he once said he always leaving his plugged in, unplugging only when he takes the boat out. I'm sure that is ok for some folks but I guess I'm always worried about something going wrong with the charger and it overcharging my batteries.

RTFM. and see how it charger operates, after my batterys ar charged it changes to a float charge, kinda on and off to maintain full charge. when mine is home its on the charger, during storage the battery switch is off, if your battery go dead easly or often when not in use there is a draw either a componet or internal to the battery, (bad cell)
