I seem to recall the "new" VW Beetle's battery was notorious for doing this when it first came out. When I worked at the battery place I saw several exploded Deutsche batteries with the tops blown up.

I have a riding tractor from the 70s with the original battery that I was jumping so that I could drive it around. Somehow I still have a face.

Speaking of battery failures... "Why won't this loving UPS unit hold a charge?" "I don't know, let's crack it open and take a look."

Those SLAB batteries don't last too long even under normal operation. There's a reason fire panel codes require them to be replaced yearly (same models of batteries in fire panels - my father installs them for a living, and my house has a UPS on almost every outlet). I even use one in my (non-e-start) motorcycle.

That battery came out of a UPS system that had been running some of our servers at work for about 6 or 7 years straight. There were four batteries in that unit, each the size of a car battery. Every one of them looked like that. I'm not real sure how it managed to keep limping along.

JD Brickmeister posted:The battery in my Escalade made a "POP" sound, kind of like a dud firecracker when I tried to start it, then everything went dead. Opened up the hood and there was battery acid sprayed inside and the battery itself had split a little. I too have learned this lesson and spent a relaxing evening cleaning battery acid under the hood with baking soda.

There were four batteries in that unit, each the size of a car battery. Every one of them looked like that. I'm not real sure how it managed to keep limping along. Just barely. Puffiness like that usually happens when cells short or other things. For fun, put a meter on them and see what their standing voltage is. The good news is that, if you find the right supplier, even the bigger ones like that can be had for relatively cheap. Most places online want close to $80 for one of the smaller 12 or even 7AH versions, but the local supplier for my dad's security company sells them for $15 to a business, or $20 individually. Yours looks like a...TR55-12? http://www.batteryspec.com/html/FireAlarm.html Unless you already knew all this, then disregard and move on.

What kind of cheap rear end UPS doesn't tell you when the battery is hosed?

No need to live with the server. Usually this stuff can be monitored remotely, or locally via USB or serial interfaces, but I assume that they didn't bother hooking any of that crap up, and unless you're in there long enough to get an audible warning, or just happen to check it, you'd never know. Yeah, it was bad management, but it likely wasn't intentional.

Just checked it and the battery isn't spilling its guts yet, though it's long past its prime by now. I only get about 10 minutes out of it now. I've been debating if I should order a new battery (since this one's original) or a larger UPS - this one is only a 550VA, and refurbups.com has some awesome deals on medium sized units. Thankfully our power doesn't go out often, but when it does go out it's out for a bit. Also, refurbups.com has some decent prices on replacement batteries.

My UPS functioned as nothing but a glorified power conditioner when I picked it up off the sidewalk. Its main function is to make a horrible squealing noise to let me know that the power is fluctuating or going out. I'm afraid to open it up because the battery probably no longer resembles its original form.

You don't want expensive devices plugged into some lovely UPS that has a melted/bulging battery in it, and most UPS's have pretty easy (a few screws at most) access to replace the battery. Also, batteries can be cheap (as I noted earlier). Why live with the risk of damaging everything plugged into it?

AlternateAccount posted:How did this not destroy other things? I'm not sure. He curbed the rim hard enough to remove a 1/4" deep, 3 inch long section. The tire bead was unaffected. The tie rod is bent slightly when new to clear the rack, so I think it kind of functioned like a fuse in the steering. Also : the metal parts were carefully placed on the battery solely for the purposes of the photo. Having experienced surprise welding once before, (many years ago) I would not make such a novice mistake again.

The Honda N600 I'm likely buying has a broken crank, wish I had a picture but how does that happen on a 36hp 2cyl 600cc engine that revs to 8000RPM?

There's an engine with a good bottom end on eBay and I found the headgasket part number and some places can get it so hodgepodge engine it is.
