Been there done that in the Mid Atlantic area. We could charge a hut in
about two hours so it would last the expected 8 hours on the spec.
sheet, if the batteries are in good shape to start with. In an eight
hour shift you could get three huts recharged, by then the first hut
had eight hours discharge and was ready for another boost.
Bad news for those folks if the batteries were old and only good for two
hours. Often the were charged during the daylight bussiness hours and
left to chance so we could go home and recharge the technicians.
You may know that much of the outside cable is now fiber, requiring
more batteries for the terminal end. Those sites for cable TV and
electronic telephone will often have small portable generators chained
to them to prevent the theft.
Yes! It gets cold out in the snow, but it gets just as difficult after
a hurricane blows through. Most big telecom companies have a few
portable generators to cover many sites. They don't usually have enough
trucks with proper hitches to tow ALL of their generators at one time.
It takes a lot of manpower and coordination. Not quite as costly as
getting a ride to AO-40 and doing a repair/recharge on her.
