I have a Cyberpower 550VA USP whose battery needs replaced. I see many
options during googling, but I'd like to find something that will last.
I know some of the generics aren't the greatest. Suggestions? Thanks!

Heh, being you can get a whole new UPS for $40...

and the replacement battery runs around $30, I really don't see the point.

Even the retail places like Office Depot and NewEgg selling the complete unit
for $52, it's still not much of a decision to make.

Besides Money, Ecologic impact should also be am important factor. It
requires a lot less land fill to recycle a battery vs replacing the whole
unit. Our Planet earth is in trouble, we have to consider it aswell as just
money.

Really?

You have a sure fire solution for getting the tree bark off your t-shirt
after you get done hugging it?

Recycling it usually means the **** is sent to some 3rd world country where
8 and 9 year old kids get to stand in mud fields in 100 degree heat smashing
the stuff into peices for 10 cents a day.

At least here in the states some landfills are being converted into methane
production green fields that'll end up as parks some day.

There is always two sides to a coin.

I've had good results with Panasonic, Yuasa, and the lesser brand
Apex.

Well, the first step is to identify the model number of your
CyberPower 550VA UPS. My guess is that it's a CP550SLG. Then Google
for "[insert model number here] replacement battery". You should find
plenty to choose from. In general, I prefer AGM batteries with the
highest weight (more lead inside). Watch out for shipping charges.
Something like this:
https://www.google.com/#q=cyberpower+CP550SLG+replacement+battery
Hmmm... 12v 5A-hr. Not much capacity and therefore not much runtime.
Let's say you have a new battery and a 100 watt load. The battery can
deliver:
12v * 5A-hr = 60 watt-hr
However, you don't want to totally drain the battery as that would
kill it. So, figure on getting about 50% of capacity out of the
battery or about 30 watt-hrs. A 100 watt load will theoretically run
for:
30 watt-hrs / 100 watts = 0.3 hrs = 18 minutes

Getting longer life from a UPS battery is not going to be solved by
simply buying a better battery. Typically, I see about 5 years of
battery life on commodity UPS's.

Having the power go out for a time, where the battery goes into deep
discharge (i.e. 10% of full charge) a few times, is going to kill most
batteries. To increase battery life, the designers would need to
reduce the maximum charge level, and turn off the UPS when the
discharge reaches about 50%. That would have a BIG effect on how long
the UPS will run on battery, which would give you something else to
complain about. You could do it with much larger external batteries,
but those cost more.

If the original battery served you well, the first thing I would do is
take it out and have a careful look at it. If you don't mind a little
online research, chances are very good that you will be able to find a
literal twin of the OEM version with an aftermarket brand on it.

Oh... and +1 on the Power-Sonic batteries - I have had good luck with
those as well.
