[Elecraft] battery care

[Thomas Beaudry]

I don't see where you got the idea that SLA batteries are meant for 
emergency use.  I saw no such statement.  Sure it listed emergency 
applications but it also listed an equal amount on non-emergency 
applications.  My wheelchair uses a pair of small 33 AH SLA's and after 
three years of constant use, are just now starting to show signs that 
they will need to be replaced eventually.
