Yes it is worthwhile. Only rarely is it not worthwhile to
replace UPS batteries, the only cases I can think of are if
you know it had an electronic failure OR if it was a very
low-end model purchased as a closeout or with a rebate which
makes the batteries cost very near as much (if not more)
than the entire UPS. I suppose the other scenario where it
wouldn't make sense is if it were old w/serial interface and
you wanted a newer unit with USB interface or that had newer
software with desirable features.
Less than half the price of buying a new whole unit. I end up replacing
the batteries in the UPS (2 of them) about every 3 years. Doesn't
matter that their voltage test passes. Problem is they lose amperage
capacity so they're uptime wanes over time.
Quite true, though if the load on the UPS isn't much and a
shutdown sequence is reasonably short duration, another
couple of years can be had out of the batteries so long as
they weren't subject to frequent full(er) discharges.
So how familiar are you with working on electronic gear? Replacing a
battery in a UPS isn't difficult but neither is replacing a car
alternator, washing maching motor, or roofing your house but many
consumers won't even attempt them. How difficult is it to get into the
case? The UPS that I buy have screws holding the outer shell halves
together but I've seen many that are press-fitted together and you could
end up destroying the tangs holding them together if you force the shell
halves apart.
Replacing an UPS battery is at least an order of magnitude
easier and faster than replacing a car alternator or washing
machine motor, etc., even if it required sliding a knife
blade around the case seams to pop all the friction tabs
apart. Roofing your house? You must be kidding. It
requires a screwdriver and maybe knife blade and plastic
shims (to keep case seams apart "IF" required to pop open
instead of using only screws) like strips of an old credit
card or cardboard, and about 3-10 minutes time. It's more
work and time just to find the battery, order and receive,
or drive to a local store to pick it up. I suppose some
parts of rural areas might make the drive a lot of "work" or
expense given today's gas prices but it's not like your
washing machine motor or alternator avoids these factors
either.
However on that model it looks more like it would have
approx 4 screws on the bottom which secure the entire top
shell, which then slides backwards away from the bezel for
access.
