Lead acid batteries are notoriously hard to predict when they will fail. Other OEMs also fail at this often.
Tesla upgraded to lithium 12V batts some time ago, which are much more predictable and last 2-3x longer.
What? No they aren’t. They almost always fail on a curve of power and voltage loss.
Also, I didn’t look it up, but I’d be very surprised if the model Y tesla didn’t require (suggest and oem?) an AGM battery. It’s still lead, but due to how they’re made they can’t get a dead short in them like older regular lead acid batteries can once they get old, although it still isn’t very common for it to happen.
Yes they are. I used to test them for a living. It’s just a best guess.
No they aren’t. They degrade before they fail. If tesla wanted to provide a warning of a failing battery that pretty much always worked it could have wired in a load test and went off voltage drop under a heavier load.
Testing if batteries are good or bad does not qualify a person to chart out battery degradation.
No they aren’t.
Yes. They are. If they weren’t, no one would have these problems. But they all do. I know everyone likes to pour over them with a microscope and drool over their flaws because they’re Tesla, but many of the issues commonly attributed to them are common with all other OEMs, you just have a bunch of armchair engineers who don’t know WTF they’re talking about.
They degrade before they fail.
No shit
If tesla wanted to provide a warning of a failing battery that pretty much always worked it could have wired in a load test and went off voltage drop under a heavier load.
Once again, I did this for a living, for a decade. We would constantly have cars with failed batteries, we would bring them in, charge them up, test them, they would pass, we’d send them on their way, and they would fail again, and come back for replacement. Our load tests also tested the alternator.
I worked on BMWs for years and they would regularly come in with the same problem, with no warning, even though they had a similar detection algorithm that mostly worked.

What other oem hides the mechanical latch?

What makes you think I was referring to the latch?
AbidanYre@lemmy.world 4 months ago
You said other manufacturers fail at “this” referring to the 12v battery dying, but the context here is a child being trapped in a car when that battery fails. If the 12v battery fails on any other car you simply pull the handle and the door opens.

I was referring specifically to the failure to detect a dying 12V battery that was referenced in the comment that I replied to.
