Default Battery chargers

Hi all,

I've just purchased a 2-bank battery charger for my 24V trolling motor. Stupid question: can I leave the charging cables connected to the post all the time (even while the motor is in use)? Obviously it wouldn't be plugged in while in use. I think the answer is yes, but I'm having a hard time finding an answer.

Second question: I've got a Battery Tender (trickle charger) for my crank batter. Can I leave it connected to the posts all the time as well (even while the motor is in use)?

Final, perhaps dumbest question: what's the difference between the wingnut posts on a battery and the larger cylindrical pole? I'm assuming the wingnut posts are just to secure the connections, and the large poles are for a different type of connect/jump starting? All of my charging goes through the small wingnut/screw posts, right?

Thanks in advance.

Yes you can leave your chargers connected all the time. The large post is for jumping or for vehicles that may require them. For the most part the larger terminals are a hold over. The wingnut post is fine for outboards and all of the electronics. However, I hope you are using nuts with lock washers?

Cars use the bigs posts.

most boats used the threaded studs.

get rid of the wing nuts and put real nuts on.

Thank you both for the advice. This boat had real nuts on it. I was thinking back to my old boat, which did have wingnuts.
