New battery is above 95% of efficiency, as battery get older and have more and more cycles, more power is lost by degrading battery inner chemistry. So in case you narrow charging to less portion of whole capacity, like discharge only to 20% and then charge back to 80%, this cycle significantly raise lifetime of battery. Triple or more.
If you have the UPS monitoring software, use it and try some tests. See how long your new rig will run before hitting the 50% charge level. Expect the total cost to be about $80 for a single battery setup with 85 AH battery and battery case. Double battery setup with 115 AH batteries should be about $160, max.
Electrical Engineering Stack Exchange Harvesting energy from old batteries? Old batteries (I mean AA, AAA -sized 1.5v ones) usually have some residual energy, which can be used, for example, to charge mobile phones/pads.
When you open the UPS box, you'll usually find either one or two gel cell lead-acid batteries. You're going to replace it / them. 1 scrap UPS - but it needs to be a WORKING UPS! You may need to adjust this length, but keep it as short as you can tolerate.
You could just connect all the batteries in parallel, each with its own diode. This way, at any instant, the strongest cell determines the output voltage while lower voltage cells are effectively decoupled - until one of them becomes the strongest and starts powering the circuit.
Those UPS devices you buy for your computer usually have a gel-cell battery that lasts for a few years. Less if your power goes out a lot. When you replace them, you pay a bundle, even if it's a standard cell. This short Instructable will demonstrate how to rework an older UPS for more capacity with cheaper battery power.
