    About UPS batteries dying, expect 2-3 years from a new one. That's because most UPS continue to give their batteries charging current even when they are fully charged. That's just the way they were designed. A smarter UPS design that does not cook batteries is simply more expensive to design and construct. I have solved this problem by replacing the standard gel cell batteries in all my UPS with motorcycle lead acid flooded units. Not only are the motorcycle batteries cheaper than the gel cells, they last longer. I am on their 7th year already and they are still fine. Just a few caveats: I can't install the wet cell batts inside the UPS housing so I drilled 2 holes in the back panel and connected thick "extension cord wires of around gauge 10 stranded wire" to bring out the + and - battery leads outside the unit to connect to the batteries. Wet cell batteries contain liquid acid, so there's the danger of tipping the battery over and spilling the acid on your floor. Wet cells release explosive hydrogen when charging and discharging, so you must have good exhaust ventilation in your room. Last, electrolysis depletes the water in them, so I have to add distilled water once a year to them. I use a medical syringe and Wilkins or Absolute bottled water.

    Another plus for wet cell batteries: Most gell cell batteries in UPS of around 650 VA are rated 7 AHrs. You get around 15 minutes of reserve power with this. Install a bigger wet cell battery, and you increase its capacity to keep your computer rig going during power interruption. Heck, you can use a car battery of 33 AHr capacity, and it can keep you powered up for as long as an hour on battery power. Just be aware that, unless it has a cooling fan inside, your UPS electronics may overheat if you go this route.

    ^ That's nice. I've been playing around with that idea for a long time. In fact, I did something similar to an old Tripp Lite (I'll post pics later) wherein, originally, it required two (2) 6V 12AH batteries. What I did was replace it with just one 12V 12AH battery (because the 6V batteries were out of stock). But it had to sit outside the case so I hacked up holes for the wires to go through.

    What's stopping me from moving to a wet cell battery are two things:

    1. Safety - Like you said, acid spillage is one possibility. Though, it can be somewhat mitigated by securing the battery to the floor or put it in a spill-proof enclosure. What bothers me is the gas it produces. It's probably ok if its installed outdoors but most domestic UPS installations are indoors (offices, living rooms, bedrooms, study, etc). The risk of fire or at the least, indoor pollution is just too great to ignore
    2. Requires a deep-cycle battery - I would think that the typical car or motorcycle battery would die prematurely when drained past a certain threshold, which is usually the case when you run the UPS on backup mode for long lengths of time. For that reason, a deep-cycle battery is usually preferred.

    I am impressed about the fact that you kept the motorcycle battery working for 7 years. Have you really drained it long enough that the low-battery warning came up? How much capacity has been lost since new?

    Good call on using deep cycle batts. They are usually for marine applications (and much bigger than what I need), are harder to find, and tend to be more expensive than the regular stuff. I use the UPS with the wet cell batts in my house for ordinary use for my desktop computers. The electricity supply has been very consistent and it may have been only twice in the 7 years that the battery kicked in while in use, and only for a few minutes. So I can't say how much battery endurance remains.

    @oj88 may I ask for the name of that company that services APC units? I have a few dead APC UPS in the office that I'd like to recondition. Thanks a lot!

    Also learning a lot from this thread. Keep it up!

    Most people I know use the APC brand. You can just plug the cable into your mac which enables the built-in UPS controls.

    They're good. Read good reviews about them and I almost bought one. In the US, the PFC sinewave series is particularly popular. Too bad it wasn't available locally when I was in the market for it last year. Not sure now tho. I went for an APC SmartUPS (sinewave) instead.

    Where can I find a reseller for APC products? I live in White Beach, Puerto Galera so I'm traveling from Batangas Port to Manila.

    I mostly buy them used online. The one time I bought new, I got it from a store in Cyberzone a long time ago.

    Anyway, I think this link might help: Reseller/Partner Locator

    Can anyone recommend a rack mount UPS? Specifically for network switches?

    Splurge on my second Eaton UPS today. An Ellipse PRO 1600 IEC. The first one is an entry level 5L 1200 model.

    I'm already fed up with the APC units I got 2 years ago just breaking down without warning (3x BX1400U-MS broke down in a span of 6 months). Even bought new batteries for those. smh

    Charging it for 24 hours before use.

    My only gripe for this model is that it doesn't come with a power cord for the outlet. Though, it does come with 2 power cords for the peripherals that will be plugged-in and a USB interface cable.

    Warranty is 3 years for the unit, 2 years for the batteries.

    Interesting. How's the output waveform like? Can't seem to find any mention of it, even in the datasheet.

    You can't really compare an APC "basic" model to that behemoth.

    To give APC a fair shake, their mid/high-end models are vastly superior. I have three Smart-UPS 700 Net (SU700INET) (pure sine wave) units, one of which I've been using 24x7 for nearly a decade. But that's not what's surprising. I actually got all of them 2nd hand and I imagine these were used for at least a few years by the original owners before they were changed out to rackmount units. I replace the batteries every 3-4 years.

    I got each one a Network Management Card and so they can be administered remotely and configured to gracefully shutdown multiple devices over the network.

    ^ You're lucky on those APCs. :)

    The model I got does not do pure sinewave definitely. Just needed to get it since I needed one for my homelab, nothing critical.

    I do want to get their 5PX model though, but no reason right now to justify at my current usage.

    About those IEC sockets, you can either purchase the appropriate cables or just use IEC to universal adapters. I find the latter a little less secure, but more versatile. Shopee and Lazada has them.

    ^ I have a couple of those adapters. :)

    The NEMA 5-15P to IEC C13 (outlet to UPS) is the one not included. But doesn't matter for me since I have tons of those lying around in the house.

    I agree. The higher model APC units are very good. I have the rack mount SMT3000RMI2U. These have 5 year battery life cycles and will need replacing next year. The only down side Is the weight. This thing is so heavy, it feels like it's glued to the rack. It took 4 people to carry it out of the car and placing it in the rack. I have a network card that I can't even install because I need to move it to slide the card at the back. I'm thinking those air bag lifters will probably help. I called my son so we can slide it forward just enough to place the network card and it won't even budge.

    Those rack mounts are heavy too. I was fumbling trying to install them, when one of them fell on my foot, and it hurt for a week. I wish I had put those sliding stickers underneath, so I can slide them.
