The Good, the Bad and the Ugly.

The big difference between the 50's batteries and today's versions is the grid spacing. Close spacing (and a sort of sponge like dielectric between) reduces internal resistance thus making higher current delivery possible. When the 50's batteries discharged they swelled up but had room to do so while they dropped sulphate off and it sank to the bottom where there was ample space for quite a bit of it. When the sulphate filled the bottom area, it caused shorting of the cell. Sometimes passing a very high charging current through one of those old sulphated batteries would render it usable for a while longer.

Now we have close spaced cell grids, little space below and wonderful cranking amps. That is unless you buy a deep cycle battery which is more like the old 50's batteries and a little better.

Interesting lnk Zonk. Looks like we'll have to watch our living room conversations if we have a smart Samsung TV.

Welcome aboard, brave new world awaits

Well, that turns me off Samsung. It's on a par with Sony putting a rootkit in music CDs that infected computers when a CD was played. They sought to control DRM. If a private citizen had done that hack, they would have gotten prison time for hacking; and maybe a terrorism charge to boot after the US Patriot Act. https://en.wikipedia.org/wiki/Sony_BMG_c...it_scandal. Never, another Sony product in my home.

That's Mrs. Mongo's car. I have a 2005 Merc Grand Marquis. I know of no way into the Merc's system except through the OBD socket.

I drive the Merc so little that it's on a Battery Tender.

If they tapped my car conversations pretty much all they would hear is: "Bleep-ing mother bleep-er, doing bleep-ing x under the bleep-ing speed limit in the left bleep-ing lane with the right bleep-ing indicator on for the last bloody-heck mile you: String("Bleep", 9999999)

I wanted to learn Binary so I enrolled in Binary 101. I seemed to have missed the first four courses. Big Grinnie

Mongo,

Just replaced the alternator in my 08 Saturn Vue and it ran me about 900. I also replaced the serpentine belt while they were there as they had to remove it anyways. This was on top of two batteries - on for this Vue and the other for my wife's 06 Vue. Now I need to find someone to recharge her A/C without telling me I need to replace the system (got a leak somewhere and have been quoted $2000+ to fix it).
