And here all this time I thought they were using VRLA to refer to the
wet cells. As I recall, wet cells have the higher overall cost,
including disposal, but are preferred for long-duration drain times for
the rated load, ie. CO. I presume "long" would = >8 hours. Cell sites,
with their limited spaces, aren't usually expected to need long drain
times, typically <3 hours, often have neighbour sites for overlapping
coverage, and portable gen sets are usually close by for more intense
times. I recall my buds talking about how Cingular eventually
dispatched 200+ field people towing gen sets to Florida during their
spat of inclement weather last year from other areas. They said it only
takes ten minutes to plug one in and come with a ~week of fuel on board.
