Happy new year

Thanks for the information.

This is the charger I have.

I know not the best charger, Can you guys recommend a proper storage
procedure for my three deep cycle batteries? Two are the larger sized ones,
looks like this one only with 700something amps listed on it. Might be the
model before this one. Both mine are 4 years old.

The third battery is a regular sized 12v deep cycle, smaller than the two
big ones, regular sized.

Hope you gents can recommend a charging or storage procedure for our short
Ontario winter. I prefer to keep them in the garage, not heated but
convenient.

Should I simply bring each up to green light ( charger stops charging) then
store them and do this once a month? Canadian Tire stores say to do this. Or
should I keep them in parellel, after fully charged and keep the 1amp
charger on constant. Canadian tire also recommends this. I don't think they
are as knowledgable as you folks, I know that 100%. That is why I am asking
you folks your opinions and I appreciate it.

73s, best regards and happy new year

I put all three on the shelf in the garage here in Ontario and tapped the
batteries together in parellel and put the charger back on the center
battery and haven't seen the green light come on that charger now for
over a
week.

It's not a good idea to put lead acid batteries in parallel unless hefty
build-out diodes are used in series with each one of them before they
are connected in parallel. If the batteries are expected to be
discharged during use, the diodes should be arranged to let current flow
out of each battery but not into it. If the batteries are expected to be
charged during use, the diodes should be arranged to let current flow
into each battery but not out of it. The batteries have *EXTREMELY* low
internal resistance and there is no chance whatsoever that their
internal effective voltages will be absolutely identical. Absent the
diodes, whichever battery wants to have a higher terminal voltage will
discharge like mad into the others, until all their terminal voltages
are the same. Then you will have a badly discharged battery and one or
more charged ones, all in parallele. Until then, make sure the wires you
use are large, since the current flowing is going to be high. Not a good
situation.

Charging batteries in series instead of in parallel has its own
problems, but they're not as serious as the problem I have just
mentioned. The worst problem with charging N batteries in series is that
you need N times as much voltage from the charger as you would have
needed charging them one at a time.
