Re: (ET) Chargers (and winch)

["Mike Finck" <M Finck setterlin com>]

With that segue I would like to move to a related topic of keeping the
batteries in my golf cart happy.  This thing sits in a cute little golf
cart garage unattended for 10 months or more, I bet temps in the garage
can reach 120 degrees.  I don't see leaving anything plugged in
unattended for that long as wise.  But I was thinking a very small array
of solar panels that would by size be incapable of creating a hazard
might be a start.  Could the panels be controlled to be truly off and
charge only when discharging hits a programmed point?

Careful!  No lead battery should be left on charge all the time.  

If the charger shuts off COMPLETELY when it's done, then yes, you can
leave 
it plugged in. Most don't really shut off, however, the go to low rate
or 
float charging.

For an application where the device is used regularly (even monthly),
float 
chargers and battery maintainers do more harm than good.  Safest policy
for 
long battery life : when the charge is finished, pull the plug.
