EPA 2023 VISIT 2 EP2 day 5

Well, today is day five at the EPA. Hey, everybody. You ever had one of those weeks? So we had the radiator fail. Fixed that six days ago now and then. This morning I woke up and my electric was all gone bye bye. I traced it back to the battery, but the battery was showing as an open in every circuit.
So I took it out. And we're not talking. a small battery. It's. It's that big, giant thing under the charger right there, But it wouldn't even charge it. So I pulled it out of the system, took the wires off, hooked my power in to the bus batteries and started the bus so I could get my refrigerator to going and get everything charging and then contacted the company for warranty.
Because when I after I pulled it out, I checked it with my my digital multimeter and it came up to be six volts. Six volts, which I don't even know how it drops to 6 volts. So obviously there was a problem, but I happened to be at the EPA. The EPA where I am, has a lot of boats and they use the same type of battery on their bigger boat.
So I was talking to my contact here, Adam. He came to check on me, see everything was going and I was complaining about the batteries, you know, God, I think I got to replace this big ass thing. Hopefully warranty covers it, blah, blah, blah. And he said, Wait a minute, I have a guy here. We'll call him the Battery Whisperer.
We have this issue where they just drop to six volts once in a while and he has a way to get them back. And lo and behold, he went and got the guy. The guy told me what to do and I have power. And it was a really quick fix. Basically what I did was I ran a couple of wires from the bus battery to this battery, jumped it for 10 seconds, took the jump off, and the battery was read an 11.57 volts on the meter.
So I hooked the charger up and of course, it was able to charge because it could see the battery again. It was no longer seeing it as an open circuit. So right now I'm just running the bus and charging up the battery with my inverter. I had to hook my inverter into the bus batteries, but if I drew that kind of power, they'd be dead pretty quick because it's currently drawing 627 watts of power to charge this battery and everything else I have going on in here.
So that would kill the bus batteries pretty quick if I didn't have it running. So I have the bus running, I have the inverter on, I'm charging everything and hopefully I can get the battery to charge up. I'm going to guess that had something to do with raining for five days and the batteries weren't coming up. But I kept checking and they were 13 volts plus.
But overnight it went from 13 volts and just like instant death, it was dead six volt, which no alarms went off or anything.
