IOwnCalculus posted:Tradition is a lot of it, but safety isn't a "one is better than the other" for all situations. Open-cockpit cars definitely have more risk of injury to impact, but you're trading that with a car that's harder to escape in case of fire / harder to extract an unconscious driver from, plus reduced visibility. As a driver of a open race car (a slow one, Spec Racer Ford), getting smashed in the face by something is what I fear most. As far getting out in the event of a fire. I got to try on the Ferrari portable F1 simulator a couple of years ago, it's tight but not unreasonable. My cockpit is downright spacious in comparison, getting out in a hurry is not hard. Pop the belts, pull the wheel brace yourself on the roll bars and floor pan cross bar and pull yourself out. However, I have been informed that if I find myself upside down, there is not enough room to crawl out from under the car. Which does not make me feel very well if I consider the risk of fire while upside down. So, my list of fears. 1) Catching poo poo with my face 2) Roll over 3) Fire The big fear with open wheel cars (Formula / Indy) is touching wheels. You just get launched into the air. See, no drama. https://www.youtube.com/watch?v=8qsmre3yAZE VV The guy who owns the car I drive almost had a snake land in his car after was launched by the car in front of him. He said "I'm pretty sure it was dead, but if it wasn't it wasn't going to be happy". Besides, I don't fear spiders, it's a Ford, not a Mazda.

Spiders isn't even on the list? they like to hide in dark spaces like the footwell, and your car doesn't have a roof to keep them out.

I remember years ago hearing about a guy had the UPS at the retail store where he worked start smoking like it was about to catch fire and they had to shut down the place until they got a new one. Until now I thought that was a bullshit story because UPSes just don't do that. Well, look like I was wrong  I can imagine that battery in a stuffy cupboard under a counter for years, covered in dust slowly bulging more and more.

I used to work in a place that thought UPSes lasted basically forever. All of the batteries, especially the ones on the servers, were long dead and in many cases were split and leaking. They stuffed them inside cube walls in order to reduce the chance that an idiot employee would kick the test button and make the SCREEEEEEE emerge. It was especially fun to pull them from under those cubes where they had eaten a perfect replica of the bottom of the UPS into the carpet and then etched the standoffs for the feet into the concrete beneath. Same job, I watched a Cisco switch burst into flame from beneath its blanket of dust in an abandoned mop closet. Seat Safety Switch fucked around with this message at 16:29 on Apr 16, 2014 |

Lead-Acid batteries last about 5 years, then it's time to replace them regardless of what battery tests say. Normally they don't fail quite as spectacularly as Fire Storm's or mine, they'll just silently stop holding a charge. Starting to bulge like that is a trait of Gel/AGM batteries, usually happens when they've suffered overheating or overcharging, but can happen when cells start to fail with age as well. This is why you should always have a support contract on your main UPS that includes battery replacement at regular intervals.

Collateral Damage posted:Which is curious because the UPS is about five years old and as far as I know the batteries have never been replaced since it was bought. For future reference, you can pick up replacement batteries for most UPS makes at a Batteries Plus for around $40 per battery. Most times, the replacement battery has a higher amp hour rating, too.

These were like 15-20 year old UPSes at the time. I suspect the cracked ones were from shipping damage or similar, at the same time we also had a shipping company drop one of our SANs off the back of a truck. You get what you pay for.

I was doing work for a very large company that shall not be named who let their rack bottom APC UPSes go for 4 or 5 years AFTER the battery warning light was on. Inside of a two week period while I was there TWO of them caught on fire and basically burned themselves into the bottom of the rack. I quickly was given authorization to replace the rest, including scheduling an emergency maintenance window (which was usually drat near impossible to get authorization for). I guess two fires + EPOs in the middle of the day was enough for them.

Most APC UPS systems use nothing fancy for batteries. It's usually a bunch of 12-7 or so Lead Acids. Find decent quality replacements, swap them out, and you're good to go. The main electronics will last a long time, no reason to buy a whole new unit.

Oh, that battery that exploded? Less than 2 years old and covered under warranty. They are replacing all the batteries on the shelf.Gorilla Salad posted:I remember years ago hearing about a guy had the UPS at the retail store where he worked start smoking like it was about to catch fire and they had to shut down the place until they got a new one. More on the small UPS side, I had to deal with a Smart-Ups 2200 that had batteries swelled up so much that I had to take off the side panels and use ratchet straps to free the battery so it could slide out the front.

So technically not a mechanical failure, but I just got done trying to register and smog my out-of-state 89 F350 with the 7.3 in California and it failed on CO by 300% at idle and 450% at 2500rpm.  That and my dad apparently repaired part of the emissions system using house plumbing. The guy said it was actually a brilliant hack but CA is anal about all of that system being stock.

Technically pre 1976 vehicles are not "exempt" but they are not required to be inspected. CARB states they should still have all original (if any) emissions equipment installed. Regarding your F350, I would seriously consider buying yourself a new cat outside of California if you still have the ability to recieve shipments out of state. This is just in case a new cat is what it is going to take to get your truck in shape to pass. There are few aftermarket cats authorized for sale in California and they must comply with all sorts of nonsense, serial numbers on the cats, and what not. They are also three times more expensive. If you show up with a new cat and still have your out of state plates, the tech will probably not be bothered by it.

Though pre-1960 something is exempt. The fact that they didn't have any emissions equipment doesn't matter. That said no one cares. My brother's 73 Z had to get CHP inspected because it had been parked since 1986. Obviously swapped motor, triple webers, and no real muffler to speak of? CHP officer said "humm, I need to drive this around the block to test it." Brought it back 45 minutes later, said "cool car" and signed off.

Tsuru posted:since they are being charged in parallel and everything is wired up directly without any electronics like diodes or current limiters. Since no battery is created equally a difference in internal resistance between batteries could in theory create weird current distributions. Yep. That's what I'm talking about. If your APC branded battery backup product retails for less than 5 figures it's probably no better than some no-name chinese brand. Ant it's almost certainly using the same batteries.
