battery charging question.

[keithdog]

I was making a repair to my Motor Guide trolling motor the other day. As I was paging through the owners guide, I came across the section of "don't do's". Most were obvious things like not to use the motor as hedge shears. But one item I read caught my attention. It said "to disconnect the trolling motor from the battery before charging the battery." I'm not sure if there is really any reason to do so, unless they are thinking someone might leave the trolling motor on while charging the battery. I don't own a bassboat with multiple batteries but I'm pretty sure those who do, do not disconnect their batteries from the trolling motors battery cables when they are recharging the batteries. I have a 12 foot jonboat with a transom mounted trolling motor. I would just rather leave the motors cabels attched to the battery and charge them at the end of the day still attached rather than disconnecting them each time I charge the battery. Is there any real reason to disconnect the cables when charging the battery?
