I’m no stranger to backup power. I’ve been working with computers for thirty five years <gasp>. A good uninterruptible power supply (UPS) is critical to keep your systems protected not only from outage, but also from electric spikes and surges.
Problem with UPS battery systems: the battery.
The biggest issue UPS systems have are the batteries. They’re usually sealed lead acid (SLA), and they require replacement every three to five years. In my experience, two to three years is more typical. Most SLA batteries have only a one year battery. (I can’t wait until some type of longer lasting lithium systems become more affordable.) Many don’t know you can replace the batteries and just throw out the whole power supply.
Today I’m writing of my APC Back-UPS XS 1300, I’ve had it for many years. This is the second time I’m replacing the batteries. Typically, the first place I start looking is online. I don’t usually go back and order the same thing, because there might be something better available.
Longest lasting SLA battery: UPG UB1280
Last time I replaced these batteries was in January 2016. An incredible five years and five month working life SLA battery. I’ve never had an SLA battery work anywhere close to this long. But I just searched again, and at time of this writing, this vendor is still the lowest cost I could find. I don’t know how these UPS batteries worked so long, and I don’t know if the new ones will last as long, but I ordered from the same vendor. When the package arrived, it was very small, but packaged well. I was surprised to find a note included saying they batteries are returnable! (Most batteries online are not returnable.)
Easy battery replacement in my APC Back-UPS XS 1300
For work, I’ve owned dozens of UPS power supplies. Many units require partial disassembly, hidden small screws, funky plastic clips. Not this APC UPS. Here’s a picture of the bottom of my well-worn UPS. The battery door is secure but easily popped open, located on the bottom of the unit. No screws, no funny clips. I replaced the two SLA batteries in less than two minutes.
