I am putting in a 2nd battery on my boat and will need an A/B switch.

Is the field disconnect one (such as this one http://tinyurl.com/pa9hn )
always the way to go, or is the one that is $10 cheaper but lack field
disconnect a better option? I do not switch to the other battery while
under power.....never have and do not plan to now. The switch will not
be out in the open for anyone to fool with.

So save the $10 bucks or get the higher priced one?


Thanks for the good discussion folks. You convinced me to buy the one
with the field disconnect. ;-)

Make sure your alternator has an external regulator. Otherwise you will be
wasting your money.
