Replacing the 2 batteries in my APC unit with 1 car battery

Posted By on May 12, 2014

apsupsunitI’ve about had it with replacing the TWO small and expensive 6 volt batteries that are packed into my APS uninterruptable power supply (UPS). Seems like I’ve purchase these same batteries too many times before for a couple of different devices and just like toner for inkjet printers, I wonder if it wouldn’t just be cheaper to buy a new unit?

This time I’m going to solder a couple extension and clamps on  this 650 watt unit and use a good but older car battery. It will both give the old device new life and also be a lot cheaper AND last longer when the power goes out!

We’ll see how it goes.
