Someone told me to never charge two car batteries at the same time,
with the same battery charger. When I asked why, he did not know.
I've done this quite a few times and never had problems. I only have
one charger. I have several batteries I use in a cabin which has no
electricity. Before I leave for the cabin I charge all my batteries.
I just use jumper cables to go from one battery to the next. It's a 6
amp charger and I just charge 2 or 3 batteries at the same time,
overnight. Why should this be a problem? Or is this guy full of ****
information?
