I have a 600 Watt / 220 Volt battery backup UPS as you normally use them for a computer and I want it to power an Arduino and a very small aquarium water pump where I don't have access to any mains power.
If the UPS is charged, it usually provides up to 10 minutes of power to the computer. My idea is to charge the UPS full, disable the speaker inside the UPS that sounds an alarm when the UPS is not connected to mains and use it basically like a battery. With just an Arduino connected and a water pump that runs for 10 seconds every couple days, shouldn't the UPS provide enough power for a long period of time (weeks, months) ?
