Robert Sember, in charge of Electrical Construction and Maintenance at 
Eaton Corp., says the standard expectancy is 3-5 years.  When capacity 
drops to 80%, deterioration accelerates.

I'm with you on this one.  It wouldn't make sense to buy a UPS just to 
get online a few minutes in an occasional power failure.

Around here, outages are likely to last from 4 hours to 4 days.  It 
looks like my best choice would be to get one of those laptops everyone 
keeps throwing away.  I could mess around with the built-in LiPo, but it 
might be in poor shape by the time I needed it.

Wikipedia says the best NiMH batteries these days have the same energy 
density as LiPo (energy per volume).  (In terms of weight, the best NiMH 
have energy similar to the worst LiPo.)  Sanyo says they'll have 70% of 
their charge after 5 years on the shelf, and apparently they'll still be 
in good condition for recharge.
