Technicalities of power supply are not in any way my expertise. Are you saying that it would be wise to change the battery?
Three, four years is a normal lifespan for a UPS-battery IIRC. Less if the batteries are used often, ie you have plenty of brown- and/or powerouts.
Most UPS-brands have a battery-exchange program.
However, in some cases it's cheaper to just get a whole new UPS... 8-/
I know I was shocked at the price I had to pay last time I replaced the APC battery. My favourite vendor sells a lot of Liebert PowerSure UPSs, so I presume they have had no problems with them, or they'd have given up by now. There is a large range, and the prices are good, but the only thing I can say is that I haven't heard anyone complain. I'd prefer to hear a positive report before buying.

Many years ago, I bought a replacement battery locally for my BBS. SHOCKING! Next time, I got on the net. Much better price. Not shocking.
I suggest you go that route if you need a battery.

Did you check Eaton Powerware? They are very competitively priced IMO. We bought APC's before as well, but I felt the controller software was not as smooth as it could've been and the battery replacement-programs very not that good as Powerware's variants.
With UPS's I prefer a brand-name. If nothing else for the reason that they stock batteries even to older models.
