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
