We have a pair of uninterruptible power supplies (UPS) on the property. Both are somewhat vintage models from Belkin. A 1000 VA model (F6C1000) in my office rack powers our network core. A smaller, 900 VA model (F6C900) in a central closet, powers those network components that live in the house. Both of them have been misbehaved in recent weeks. At this very moment they are basically non-functional.
I’ve long believed that the network core should survive minor power line irregularities. This belief stemmed in part from our migration to IP-based telephones for home & office. Our phone service should survive a power line bump. With both UPS in their fault-riddled state a loss of line power, even just a power line switching bump, caused our entire network to go down. This situation eventually had to be addressed.
The sealed batteries is consumer UPS such as ours have a fixed lifespan. At a certain point they simply cannot retain a charge, and the device throws an error. From that point onward they become nothing more than an overweight outlet strip.
Replacing the devices with similar, new models would cost $100 – 200 each. However, if I were to replace them I’d prefer to upgrade to dual-conversion models, instead of their cheaper, line-interactive cousins. A dual conversion design provides cleaner power under a range of line conditions. That upgrade would double or triple the project cost.
I know from past experience that someone handy with a screw driver can replace the batteries in a UPS. So, I’ve just ordered replacement batteries for both of these Belkin devices.
The replacement batteries, purchased via Amazon, come from third party suppliers, which is a good thing since Belkin actually exited the UPS business some time ago. It seems that tablet and cell phone accessories are a more profitable business.
This is the third set of batteries going into the larger UPS. At some point it won’t make sense to replace the batteries again. For the moment, it still makes more sense to replace the batteries than to incur the replacement cost and pay to send the old devices off to an electronic recycler.
