Sealed type batteries are often avoided for backup power source applications for several
reasons. One reason is that the state of charge of sealed type batteries cannot be ascertained
by the usual specific gravity measurement. Reliable alternative methods to measure the state
of charge for sealed type batteries are under development. A second reason is their
sensitivity to high temperatures.
