Charging the batteries 88 F-250 non turbo

Is it ok to leave all connections to and from both batteries when using a charger? And also,does it matter which one you start with if indeed it is ok to leave on the connections?
How about on my 92 F-250 non turbo?
Thanks, Robert

There has been much debate about this a few months ago...
But no, it does not matter if you leave the connections on the batteries to charge them, and I also stand by my opinion (a few will disagree) that it does NOT matter which battery you hook the charger/jumper leads to, assuming you have heavy enough cables (factory size or larger). If you have the proper size cables running from one battery to the next, then on to the starter, the whole arguement of having to hook to the passenger's side battery is essentially a moot point. Copper cable is obviously a very good conductor with minimal line losses, therefore it is an insignificant difference as to which battery you hook to. Just use whichever is more handy for you.
