John,

As I recall it was about an 80 amp hour, sealed lead acid, deep cycle 
marine battery (bought at the local marine supply outlet).  The 
enclosure was an aluminum box that held the battery and gate controller 
circuit board.  It was not air tight.  I recall it had a couple 
unscreened vent slots, because I was concerned about insects (yellow 
jackets) getting in.  The gate opener was in operation (used regularly) 
for about a year.  Then left unused several weeks.  The next attempt at 
use, it did not work and the owner opened the box to find the battery 
exploded.  An identical opener nearby, with an identical battery, that 
had been used regularly, was checked and the sealed battery cap was 
removed for inspection.  The battery was dangerously low on 
electrolyte.  SunGuards and new batteries were installed in both gate 
openers and they have worked flawlessly since (about two years.)

take care,

Randy Brooks
