Apc es500 vs es550

[86waterpumper]

I have two apc units at work, one is a es500 (be500r) the other is a es550 (be550r) They both have the same number of outlets, both take the same size battery, so is there any benefit at all to one over the other?

Probably doesn't matter, there's only a 30W capacity difference between them.
