U.S. NAVY THEORY OF LEAD ACID STORAGE BATTERY TRAINING FILM 25634

So since i don't see sn exact date this video was produced and because it's talking about lead acid submarine batteries I'm assuming its during ww2. When the narrator describes an atom I noticed he did not mention the neutron and this is a unique piece of history here. Despite the neutrons discovery in 1932 it was not as widely accepted as it is today. "On 29 December 1934, Albert Einstein was quoted in the Pittsburgh Post-Gazette as saying, “There is not the slightest indication that [nuclear energy] will ever be obtainable. It would mean that the atom would have to be shattered at will.” This followed the discovery that year by Enrico Fermi that if you bombard uranium with neutrons, the uranium atoms split up into lighter elements, releasing energy." which eventually led to Einstein signing the letter sent to President Roosevelt warning him of Atomic weapons to come and urging him to invest in a program. Because of how secret squirrel the Manhattan program was nuetrons were not widely taught or twlked sbout in the United States during the war but late 1945 couldn't get people to shut up about them. I just thought that it's cool to see that.

before nuclear physics took off people were informed

remember when you could maintain something?

That intro music makes you think you're going to experience the most glamorous and dramatic drama to ever hit the planet. Then, the title pops up about some theory of lead acid batteries lol. Still a fantastic video, but the most insightful thing is that the military really knew how to just bring a banger on the intro.

Excellent video learned a lot

The chapters in these videos make it harder to navigate the video on an iPad: As often as not when one tries to move 10 or 20 second see one ends up moving by chapters. Backing up to go over something can be an exercise in futility.

When I was in high school some 50+ years ago, I worked in a full service gas station (as most were at the time). One of the services was to remove the caps on the car batteries to check the fluid levels. Often it would be so low, the tops of the plates would be exposed. We had a water jug that had a spring loaded valve in the spout. The spout would be inserted in each cell and the water would flow into the battery until it reached the fill line.

I performed that action hundreds of times, but never really knew why plain water would keep a battery working.

I was a toddler, in the first grade, when this film came out!
Thank you for it

🏆🏆🏆🏆👏👏👏👏👏

You folks have some of the best videos. When I was a kid in the 60s I remember being so bored in school by stuff like this... Now I cant get enough of it. Thanks for what you do!

We should be making more educated films like THIS & NOT reality tv. This is WHY our ancestors were so smart & never went to college.🤔🇺🇸

When this film was recorded in 1940s there were 102 known elements to day in 2022 there are 118 known elements.

Very good explanation thanks for sharing

Bad memories of diving the battery well as electrical officer on SSBN 620. Good training film though.

Why am I watching this at 1 in the morning. My head hurts. I remember watching this in my early military days. We would top up the electrolytes with distilled water on a weekly basis.

Very good educational video!

I intend to try and recondition my failed solar batteries and this video was essential viewing. I had to watch it twice to get the full jist of it because my previous understanding was at odds with this explanation.
