Was helping my son move from Tuscaloosa to Birmingham - had to buy a new
battery in Tuscaloosa. Went to Walmart - got the battery - installed in
my '88 GL - and continued the move. Got done with the move - got ready
to go from his new place to mine - Engine turned a couple of times -
then quit. Apparent dead battery. Pulled the battery, son drove me to
the nearest Walmart with a service center. Before attempting to put a
new charge on it - they tested the battery. It was dead. It was not
going to take a charge. Left with a new replacement battery. Under
warranty of course. New battery lasted several years.

Failures right out of the box - so to speak - do happen. In my flying
days I bought a King DME abox - Distance Measuring Equipment - used in
flight to check ground speed and distance from navigational facilities.
King at the time was top of the line in radio nav gear. Paid $5000 for
that box. Radio shop installed it - and I went t the airport - picked up
the airplane - and departed. The DME worked fine until I got 15 miles
out from the airport - suddenly it just quit. Turned around - went back
to the radio shop where they pulled it and put it on the test bench. It
was DOA. They were never able to even get it to turn on. Put another
brand new unit in - and it worked fine for  me until I sold the airplane.

Moose nuggets happen!
