Not much is going on this week. They haven’t pulled the plane in to start the annual yet, but they are working on approval to upgrade the battery to a LiFePO4 model that not only provides more cranking power but also weighs fifteen pounds less than the standard lead acid unit. Since such technology did not exist in 1981, and the feds (spit!) being what they are, permission is required. I’m looking forward to a fifteen-pound increase in useful load, if it can be made to happen.
We had a bit of a breeze on Sunday. If sustained winds near thirty and gusts over forty miles per hour can be called a breeze. I have a 10×17 Harbor Freight shelter housing my backup generator, my backup lawn mower, and during the winter, my Benelli micro-motorcycle. The main part of the cover disintegrated last year, and I chose to replace it with a heavy-duty tarp, hoping both for lower cost and longer life over an original replacement. I used rope through the grommets on each side to secure it to a line attached to anchors in the ground, and it worked well. It weathered high winds many times, so I wasn’t worried about it.
Wife texted me early Sunday afternoon just after church, telling me that the shelter had collapsed. The rope that I had used to secure one side of the tarp was old when I installed it, but it appeared serviceable. In the months since, it weakened enough that, when the enthusiastic wind ballooned the tarp, it broke. That allowed the tarp to blow across the top of the shelter to the still-attached side. In the process, it caught the last section of the frame and pulled it loose from its clamps and the rest of the shelter, laying it against the tractor that is parked at that end.
I feared major damage but found none on Monday morning when I inspected the situation. The frame sections are only slid together at the top, with a single clamp at the bottom. The original cover incorporates straps that pull everything towards the center, making that an acceptable design. The way I had the tarp attacged did the same. With it loose, it didn’t take much to pull things apart. I reconnected the three pipes together and drilled a small hole in each, through both sections of pipe, and installed a screw in order to improve the situation. Then, I re-tightened the clamps at the bottom.
That was all I had time to do before work on Monday. Yesterday, I pulled the tarp back into place and secured it with individual pieces of paracord at each grommet. This will prevent any single failure in the future from releasing the whole tarp or even one side. The other side still uses a single section of rope for the entire side, so the potential for such a scenario still exists for that side, but at the moment, it is functional. And I ran out of time before I could address that. Everything is back under cover at the moment, so crisis managed, priority lowered.
Yesterday evening, Wife texted while I was at work with another situation. The power blinked momentarily, and a noise began at the same time. She also had no wifi, even after the power came back on. Obviously, it was the UPS. While it usually works as expected, sometimes, depending on the duration of the blink, it can lose its mind and require cycling power to reset. I walked her through locating the unit and how to turn it off and back on. It’s stupid about having to hold the button down for such things rather than a simple press and release.
I thought the issue was resolved, but about twenty minutes later, she texted back and said that it was steady alarming again and the modem and router were off. Odd, as there was no second power blink. She wanted no parts of trying to reset it again, choosing instead to just use her mobile data for anything that would normally use wifi. I figured the UPS was toast and told her that I would look at it when I got home.
When I got home, I reset it and waited for it to do something stupid. While doing so, I came up with an alternative to just plugging the modem and router directly into the power strip and having no battery backup. The plan I came up with was to use the power station formerly reserved for aviation use to power a pure sine-wave inverter, via which I would power the router and modem. Leaving the power station charger plugged in would allow it to float during normal operation and seamlessly switch to battery in the event of a power loss. I couldn’t use the power station’s built-in 110VAC outlet as it will not allow charging when said outlet is in use.
I hit a bit of a snag, though. Whenever I plugged the inverter into the power station’s cigarette lighter outlet, it would disable that output. It was like the connector was shorting out the outlet. I’d used the inverter last week for another purpose using a different power source, so I knew it wasn’t the problem. The inverter was off, so it wasn’t overloading the output capacity, either. The cigarette lighter outlet worked fine for other things, so that wasn’t the issue. I tried different things and eventually got it to work with a portable cigarette lighter socket connection plugged into the power station’s 12V barrel connector output. All this allowed the UPS plenty of time to get stupid again. It never did.
I unplugged the UPS from the wall to test its backup functionality. It immediately went into a full alarm. Probably the battery, maybe the unit itself, but it was almost midnight, and I was done arguing with electronics. I dragged the power station and inverter over, hooked it up, verified operation, and went to bed.
This morning, the power station was fat, dumb and happy at 100% charge and 11.9 volts on the output while powering the modem and router. Just like it was when I left it. At least that is reliable as a backup. I removed the battery from the UPS and put a meter on it. It measured 9.0 volts. It’s a normal 12V sealed lead acid battery, so it should’ve been at least 12.5 volts. The battery was ancient, so that was no surprise. The surprise was that nine volts was enough to power the alarm buzzer.
Off I went to Amazon to search for a new battery. It’s a tiny UPS, 350Va, and the battery is likewise very small. I couldn’t find one with the correct dimensions, and the closest cost more than I wanted to spend. Then I remembered a possible solution.
Back in 2019, I bought a marine deep cycle battery for the trailer that I used for the tractor when I took side jobs. I wanted something to directly power the winch that I installed on it rather than trying to pull that much amperage through the trailer lighting harness. I’d removed it a year or two ago when I quit the side jobs, and it had just been sitting ever since. I put a charger on it a few times a year to keep it charged but never used it again. I figured it was dead, given its age and lack of use, but I hooked the charger up to it.
I then went about fabricating wiring to connect it to the UPS, just in case it was still serviceable. The UPS’s charging circuit is probably in the milliamps, given the size battery it is designed to use, and is unlikely to do much for such a large battery. Also, despite the successful charge (according to the charger), I doubt that there’s very much capacity remaining in the geriatric battery. Even so, I hooked it all up, reconnected the electronics to the UPS, and let everything boot up. Shortly after, I unplugged the UPS from the wall to see what would happen. It immediately switched to battery power and did the short beep every minute to indicate that it was running on battery, just like it’s supposed to do.
Since the pull for both units is only about fifteen watts total, I estimate that I can get a week or more of constant use out of that battery, even given its age and likely diminished capacity. The tiny trickle of charging current that the UPS is able to deliver should keep it close to fully charged since we typically only lose power a few times per year. One more problem solved.
And that is how I’ve managed to avoid boredom this week.
