After the dust from a failed UPS battery settled with a spare installed, I learned 1500Va is only enough to run the pond with both pumps and the UV light for around 15 minutes – not enough in my estimation. So I snagged a re-furb’d Smart-UPS 3000 off eBay for about half price new. With any luck, they just put a new battery in it. Only problem was getting it installed. The damn things weigh almost 100lbs with that much battery in them. I was able to get it done by suspending it under the shelf on a rope and cinching it up a few inches at a time until it was in place to bolt in.
