Final resolution of this thread....

Thanks, Anthony, for that recommendation.  They were most helpful over the
phone and as part of the deal they installed the new battery and took our
old battery for recycle.

We got warned during our research that removing the battery from old UPS
units can be extremely tricky because of swelling, and that turned out to be
the case for us; it was a tremendous (although eventually successful)
struggle to get it out.  (Battery Direct would have been willing to do that,
but we needed to get the battery out to obtain the voltage and Ampere-hour
rating so that Battery Direct would know they had the appropriate battery in
stock--- catch 22.)  Actually, the battery supplied by Battery Direct had
a 10 per cent higher Ampere-hour rating which is nice.

I have tested the Back-UPS 450 with new battery first with a 200 watt lamp,
then with the computer in grub menu mode (which I always configure for
infinite timeout).  In the grub menu case, the computer did not go through
the reboot sequence when the power was cut off while with the old battery it
did.  Thus, the UPS with new battery is now working properly again (e.g.,
battery replacement seems to have made all the difference).

I hope this battery lasts as well as the previous one (10 years)
although I understand 5 years is more typical.
