Definitely lead acid for us. OEMs often use NiCad but they are pricey and
come with the risk of thermal runaway at no extra charge... I hear the risk
of TR isn't what it used to be when they first came out with nicads, but some
herky lead acids seem to be a popular retrofit. Plus you can ship them if you
find yourself low on juice somewhere.
It also looks like there are quite a few UPS for sale with the caveat "needs
batteries"!

Are you sure they are lead-acid ? The ones my helicopter pilot buddy used
to give me were nickel-cadmium.
FWIW, some APC UPS units at least used to have external battery connections.
