The SUPER UPS Battery Hack,. Have you ever wanted your electronics to run longer on battery power? I have. So now they do. I swapped the tiny SLA batteries in my APC battery backup for two deep cycle batteries to get ludicrous run time. This procedure would work with CyberPower brand just as well as the APC that I have. The key is to match the input voltage to whatever your UPS is using now, which is most likely 24v. I've never seen anything other than that. You'll need 24 volts worth of batteries, a UPS, some wire, terminals, a fuse and holder. Check it out!
