What do y'all think electricity is? Voltage is just a difference in charge density. Charge wants to flow to areas of lower charge density, and we make it do work on it's way there. Lead peroxide has been oxidized, and thus has less negative charge than the plain lead. Given the catalyst of aqueous H2SO4 and the wire connecting the plates, charge density is able to flow from the lead plate to the (+) lead peroxide plate via the chemical reaction detailed in the video. If you just charged a metal plate by sending electrons to it, it would be susceptible to discharging through the air. By locking the electrical difference into the metal through oxidation, you ensure that the plates won't discharge unless the catalyst of acid and the wire are present. You can easily disconnect the wire through a switch to turn the "catalyst" on or off, thus turning the battery on or off

I really don't think this is right, it emphasized it so much in the video but you are infact adding electrons and holding them there. From what I gather it's lead going from +2 oxidation state to +4, +4 has 2 more electrons. So I think it really is holding electricity.

It was interesting how the ways lead acid batteries "die" was covered at the end and it still holds true today.

@vondeliusc Funny you mention this because I had a new battery from NAPA about 4 years ago, and within the warrantee period, I guess a year in maybe, I go out to start the van and the battery was basically dead, hmm, ok, how? I thought maybe a courtesy light/dome light was left on or a door not shut completely, charged the battery, it would be fine for I guess a few days or maybe a couple of weeks and then again it's dead! I went thru that 3 or 4 times and decided to go back to NAPA and have them test the battery, because by now I KNOW 100% no lights were left on, the radio was definitely OFF, all the doors definitely closed etc. He took the battery out and bench tested it in front of me, with TWO different test devices and both said the battery was "good" the alternator and all were in good condition and charging the battery correctly too. Made sure the battery was 100% charged again. Couple of weeks later the batter is dead again!!!! So I went back to NAPA, and it's a small town local shop and I know the owners well for years, so I said, can we just exchange this battery under part of the warrantee, I'll pay what ever the pro-rated amount might be but don't want him to be out money on the exchange, let's just get this battery changed out. Well, he exchanged the battery for me with a new one and told me don't worry about the pro-rate, it's taken care of. The replacement battery has performed flawlessly since, so it WAS a bad battery and what ever was wrong with it TWO totally different battery load/diagnosis testers they used at the NAPA store said the battery was good! Sometimes you have to just ignore what such test devices claim, and just go with your gut feeling

So the mechanic didn't fix that car, he just installed a new battery "I look forward to see you again", right?

A lot of lead handling there. I wonder if any of these men suffered from lead poisoning in the later years. . However, this is very fascinating.

Man I dont know how I missed this but im glad I found it: Back in the early 80s I worked on an old X-Y telephone switch we had a back up battery system that was installed in 1966 the batterys worked phenomonally, just routine Specific Gravity checks and periodic charging and they would humm along for upto 8 hours in a power outage. I saved those batterys when they decommisioned the switch in 1987 used em in DRMO purchased C-10 and Dodge crewcabs I bought on station also decommosioned. some are still running today. They sure dont make batterys like they used too!

Awesome!

Can we go back to the 1950s? I don't like the 2000's anymore.

A great exhibit of the chemical nature of lead. Most of the electronics today have RoHS, (restriction of hazardous substances) which includes lead. One of its great virtues is its recyclability, from then (1959) to today (2023). The lead acid battery looks to be around for some time to come, while it remains the most cost effective device in automotive applications. The lithium cells have come a long way, but still prohibitively expensive...

@Hopeless_and_Forlorn

Careful how you use the term, reversed polarity. It is true that current in the battery does reverse when the voltage at the positive terminal is increased to a level high enough above the battery voltage to overcome the battery's internal resistance, but the voltage at the terminals never reverses. For an automotive battery of the period illustrated, a voltmeter across the battery would indicate about 12.6 volts at zero current, drop a little below 12 volts as the engine is started due to the high current draw through the internal resistance of the battery, and then rise to a regulated 14 to 14.2 volts or so as the generator operates at normal engine speeds. The difference seen with the replacement of the generator by the alternator in the early 1960s was mainly in the superior ability of the alternator to maintain sufficient current output and regulated voltage at engine idle speed.

Starting batteries have thin plates and many of them per cell to give high amps for a short period of time. Deep cycle batteries have thicker plates and fewer of them per cell. In either case, a fully charged lead acid battery that has not been charged / discharged in 8 hours will read about 12.66 Volt and a fully discharged battery about 11.70 V. Running a battery to full discharge will damage it by growing hard lead sulfate on the plates so don't go below 20% state of charge, just below 11.94 . Below is a state of charge table. Also, as the plates become coated with hard lead sulfate or the material falls out of the grid, the battery in effect loses capacity but not voltage. The chart, note a slight difference in voltage is acceptable. If just removed from a charger, the voltage will be high , if just removed from a load, low. 12.66 100% 12.42 75% 12.18 50% 11.94 25% 11.70 0%

The structure of hydrogen peroxide is, roughly, H-O-O-H; the O-O part is the peroxide. So, looking at the equation, PbO2 could be "lead peroxide", and that's where the term of art comes from. HOWEVER, the structure of PbO2 is, roughly, O-Pb-O So there's no peroxide ion in that structure, so PbO2 ISN'T "lead peroxide." It's "lead dioxide."
