Is anyone familiar with these battery operated sump pumps?
What do they use for batteries? What voltage? Are the bateries
always being charged when the power is on, or must they be connected
to a charger manually? Can more than one battery be connected in
parallel so they pump longer? Can they be run off a car battery in
an emergency?

I believe you will find most are 12V and will run off a car
battery, but they likely come with a NiCad type battery. I would
suggest that unless you expect short outages or only need it when it
is not all that wet, that the battery may go out before the water
stops rising. After all, most power outages happen during storms and
that is when the pump is needed the most.
I like the idea of a water powered backup, unless you have a well.
Even when the electric goes out, you usually have water pressure on city
water system.

I should add a couple of notes. 12V nor water powered pumps seldom if
ever have the pump capacity of the typical sump pump. In an emergency they
may work, but if there is a lot of water to pump they may not be able to
keep up.
