motor. So, when I take the boat out and use the electric motor, I
need to recharge the battery when I get home.

Just use a cheap timer to charge the battery for 10-12 hours after you
return from fishing. The battery sitting unused will not discharge
much.

About using a timer..., if I use a timer and the timer turns off the power
to the battery charger when the time is up, the battery charger will still
be set to "ON" and it will still be connected to the battery. Is there
any problem with that?

Somehow, that seems like the battery charger circuit will still be
connected to the battery, and the battery will discharge back through the
battery charger. On the other hand, if the battery charger switch is set
to "OFF", and the battery charger is left connected to the battery, I
assume that the circuit between the battery and the battery charger is
disconnected.

But, with the timer approach, there is no way to switch the battery
charger switch to the "OFF" position at the end of the pre-set elapsed
time.


Never saw a problem with the charger I used. I very much doubt any dumb
charger has any difference from it being off and no power to the charger.
