[AT] Battery Charger recommendations

[Bill Brueck]

Wouldn't just putting a thoroughly drained battery in parallel with a good
battery for a brief time recharge it enough to then charge it with a
charger?  If not, add the charger to the parallel set, that would start the
charging.  Sort of jump starting a dead battery...just the battery.

If you have an antique tractor battery that is so dead and flat that it
won't take a charge, try this(outside, and vented):  Put the charger on
start mode for 30 seconds, rest the battery for two minutes, and repeat 2-3
times.   This has worked a number of times for me - once recently with my
truck where the air conditioning switch went bad and the compressor clutch
stole every electron out of my battery.   Nothing would charge it.  Brought
out this old trick and still using the battery today. 

If the battery still refuses to take a charge, put it on the desulfate mode.
If that doesn't work, take it in to the auto parts stores.  Odds are you'll
find structural issues such as a bad cell.
