Interesting information on the two step reaction that produces Cl2 involving H2SO4 and PbO2. I had read before of the hazard of Chlorine from Lead-Acid batteries in a maritime environment.
the first US subs had open top LA batteries, and Gasoline motors. talk about hazardous conditions. take your pick, Chlorine gas, Hydrogen explosion, or perhaps a Gasoline vapor explosion. truly a sink by themselves class.
I had an uncle that served on a sub in the Pacific - also i spent my yrs working on generators in the offshore oil fields - Many of the fairbank OP engines on rigs came out of scrapped subs after WW2 - Two of the senior electricans i worked for were retired sub chief electricans - most dont know a lot about lead acid batterys - were i live in the deep south - Befor REA strung wires out here those with electricity in there homes were powered by house battery's - Some homes had 6 volt power and others had 32 volt power - a standard 6 volt house farm battery was about the size of 4 golf cart batterys or larger - Those with 32 volts had 16 cells and if the barn was more than 100 ft some had 17 cells - The service life of sub batterys was shorten often due to the high charge rate - Also the acid strength could be 1.350 - that alowed for a 85% charge rate in one houre - but the service life was often shortened with the strong acid and fast charge rate - In the early 1960s when REA finished stringing wires out here - most who had homes that were powered by 6 or 32 volts did not want grid power - Back then it was $500 to bring a pole and transformer to a house and the power was 35 cents a kw - Farm gas was 12 cents a gallon and trucks filled bulk tanks on farms - Most charged there farm house battery's all day friday and during the summer the fans ran a lot along with fridges and freezers - so many had to charge on monday also - My grand father started working on farm light plants generators and batterys in 1900 - Batterys that used a acid strength of 1.220 normaly lasted 40 yrs or more - as long as it doesnt get down to zero degrees they could use a acid strength of 1.195 - My grandfather often told farmers that those battery should last at least 60 yrs or more - Farmers could generate power for less than 2 cents a kw - so they stayed with battery powered homes for a goood while longer- With weaker acid, plates dont swell, or shead much - also there is all most no termanal corrosion - There is little sulfation and they use very little water - The down side is you have to imcrease the size of the battery bank with weaker acid there is a bit of cappacity loss -
Thank you so much for providing infos about such a niche subject ! I am currently reading the book Das Boot by Buchheim, so I was wondering about detailed Uboot battery functioning, especially since the author wrote about battery acid level. Very interesting stuff and great work you done there. Thx again
I had read that if there was a leak in a battery, there was a procedure the submarines crew could try to neutralize the hazard of the gas. Can you tell a little bit about that? Great video.
To my knowledge U-boat crews did not have a method for removing hydrogen or chlorine gas other than surfacing and airing out the boat. You can use sodium thiosulfate or sodium bisulfate to neutralize chlorine but in a U-boat they would have had to have cartridges that they could insert into the ventilation system and to my knowledge they did not do this.
@@brucetullysubmarine battery's are not any different then golf cart battrey's - there made about the same but much larger than golf cart or electric fork lift batterys - There is a tube that goes to the bottom that air is used to bubble to mix the acid - the caps have a attachment that draws the gasses of the battery's off and the hydrogen is burned off in a catalyst

Many of the fairbank OP engines on rigs came out of scrapped subs after WW2 -
Two of the senior electricans i worked for were retired sub chief electricans - most dont know a lot about lead acid batterys - were i live in the deep south -
Befor REA strung wires out here those with electricity in there homes were powered by house battery's -
Some homes had 6 volt power and others had 32 volt power - a standard 6 volt house farm battery was about the size of 4 golf cart batterys or larger -
Those with 32 volts had 16 cells and if the barn was more than 100 ft some had 17 cells -
The service life of sub batterys was shorten often due to the high charge rate -
Also the acid strength could be 1.350 - that alowed for a 85% charge rate in one houre - but the service life was often shortened with the strong acid and fast charge rate -
In the early 1960s when REA finished stringing wires out here - most who had homes that were powered by 6 or 32 volts did not want grid power -
Back then it was $500 to bring a pole and transformer to a house and the power was 35 cents a kw -
Farm gas was 12 cents a gallon and trucks filled bulk tanks on farms -
Most charged there farm house battery's all day friday and during the summer the fans ran a lot along with fridges and freezers - so many had to charge on monday also -
My grand father started working on farm light plants generators and batterys in 1900 -
Batterys that used a acid strength of 1.220 normaly lasted 40 yrs or more - as long as it doesnt get down to zero degrees they could use a acid strength of 1.195 -
My grandfather often told farmers that those battery should last at least 60 yrs or more -
Farmers could generate power for less than 2 cents a kw - so they stayed with battery powered homes for a goood while longer-
With weaker acid, plates dont swell, or shead much - also there is all most no termanal corrosion -
There is little sulfation and they use very little water -
The down side is you have to imcrease the size of the battery bank with weaker acid there is a bit of cappacity loss -

Thank you very much for the feedback! Das Boot is a great book but it reads a little like the Odyssey :)
موضوع جميل جدا
كنت اتسأل دائما ماهي التقنية المتطورة في البطاريات المستعمله للوحوش الالمانيه التي ارعبت السفن في الاطلسي
Very interesting video!
Thank you!

@@SubmarineHistory thanks for the quick reply. I thought they could put a base in the bilge, to help with that.
Gaston Plant ... Americans are always on a mission to mis pronounce French and German to the max. ;)
Italian too. ;)
Hi, are the battery's recorded
How they were made
I'm not sure I understand the question - are you asking if there is information out there on how the batteries were made?
@Submarine History yes on how they were made
@@brucetullysubmarine battery's are not any different then golf cart battrey's - there made about the same but much larger than golf cart or electric fork lift batterys -
There is a tube that goes to the bottom that air is used to bubble to mix the acid - the caps have a attachment that draws the gasses of the battery's off and the hydrogen is burned off in a catalyst
Whew!
