There are some interesting developments in Europe on required standards 
for CPE (including ONTs) for low-power and 'green' always-on devices.
see Code of Conduct on Energy Consumption of Broadband Equipment 

Also note advertising such as at 

"...Fully compliant with the European CoC power consumption levels 
(L0/L2/L3), the Velocity chipsets' power profile is the industry's 
lowest at less than 1 W per port, over 30 percent power savings compared 
to the next best A/VDSL chipset offering."

(yes this is copper, but the Euro Code of Conduct is intended to drive 
power usage down in all CPE)

As for replacing batteries and needing technician truck-rolls - meh - 
make it user-replaceable, add an audible alarm and flashing light when 
the battery gets low, and re-use the distribution (and recycling) chain 
for telephone books to throw a new battery onto everyones lawn every 3 
years. A small gell-cell would have to be lighter, smaller and more 
efficient to distribute than 2 volumes of the Sydney white-pages.

Maybe a new service provided by your local council - leave your used 
battery by the bins for recycling when the rubbish is collected, and the 
garbos leave a new one in the morning.
