World War II submarines were powered by large electric motors. On the surface, the motors drew their power from diesel generators, not unlike how a diesel locomotive operates today. When submerged, the diesel engines could not be operated, and the motors drew their power from huge banks of electric batteries. After the batteries were drained of their power, the submarine would have to surface in order to run its diesel generators to provide propulsion and electric power to the submarine. During this period, the sub's batteries were recharged. Toward the end of World War II the submarine snorkel was invented, which gave a submarine the capability of running its diesel engines while submerged. The submarine was required to stay relatively close to the surface, but it was fully submerged with the exception of the snorkel mast.
Nuclear powered submarines also have banks of electric batteries, but they are only used when the main propulsion plant and/or its steam-powered electric generators are disabled. When a nuclear-powered submarine's batteries are fully drained, they are recharged by the boat's diesel generator if its steam-powered electric generators are not available, or by the steam-powered electric generators when they becomes available. Just like a diesel-electric submarine, a nuclear-powered submarine must operate its diesel generator on or near the ocean's surface.

How did they heat a World War 2 submarine?
WWII era submarines were heated by Convection Air, direct Steam or Hot Water Radiators, and Plenum systems (forced air duct ventilation). Running diesel engines to recharge batteries on the surface were also great heaters, and still are today, though a bit noisy for most.
What are the disadvantages of World War 1 submarines?
Limited underwater speed and battery capacity, they often had to surface to recharge the batteries, a dangerous job, as fumes could be discharged making the ship a sitting duck for even a low flying scout plane with incendiary bullets- or tracers, aim for the battery boxes. The Russians, give "em credit aimed at eliminating part of this hazard with their Turbo-electric two-shaft A-9 class of Fleet or as we would say task-force submarines.designed to operate with surface craft. these had high surface speed- as did the much later Gamma Boats, and could recharge the batteries at ( Siphon depth) with about 2/3 propulsive power available. no US sub could do this at that time (ww-l;) The A-9 was the top=-fleet almost said top-flight Czarisr Russian sub.
Did submarines have weapons?
Torpedoes are the main armament. older Diesel submarines had deck guns for surface defense and anti-aircraft, but the modern ones do not have fixed deck armament. Of course FBM submarines carry Guided Missiles. More: Most WW2 Submarines carried several torpedoes, and had 4-6 forward firing tubes and 1-2 rear firing tubes. Older subs were not intended to run submerged full time the way modern subs do. There was no snorkel mast (technology taken from captured German subs at end of WW2) on most subs and they had to run on the surface to recharge their batteries for submerged operations. They also were faster on the surface than submerged. So they had surface weapons in addition to torpedo tubes. Usually a main gun, about 5 inches or so; and an anti-air gun similar to a .50 cal. The measurements would vary depending on the country as the US uses standard measurement and most other countries use metric.
Which assets became the US Navy primary strike assets after the Japanese attack on Pearl Harbor?
Submarines and Aircraft Carriers
How many US submarines were lost in World War 2?
52 US submarines were lost in WW2. This was about 1 in every 5 submarines that the US had in WW2
Will the Sony Xplod recharge rechargeable batteries when I plug it in?
No the Sony Xplod will not recharge batteries when it is plugged in.
How can you recharge batteries?
You can only recharge rechargable type
How was the motor of an old submarine operated underwater?
All pre-Nuclear submarines were operated underwater by Electric motors connected by to the main propeller shaft. Even today, modern nuclear submarines have an emergency electric motor connected to the shaft as a backup. The motor was powered by DC Batteries taking up much space in the lower decks of the boat. Prior to the development of the submarine snorkel, older submarines were required to surface and start their Diesel Engines in order to recharge their batteries. Even today, modern submarines typically use a Diesel-generator to recharge the Batteries, as they are crucial to any emergency/casualty situation on board if the situation requires Reactor shutdown or scram. Modern Diesel-Electric submarines still use the same method of propulsion as the older boats did - electric motors powered by DC batteries that are recharged by Diesel Engines. The difference is that today's battery technology has given newer DE's the capability of much longer submergence times before recharge is required. Where hours were required in earlier boats, weeks can pass before a modern DE needs to recharge.
Can you charge your camera with outt the charger and with the batteries?
The camera operates on batteries,weather nicad( rechargeable) or alkaline or lithium. So no matter what,you must recharge batteries. If you purchase rechargeable batteries and the charger, you can recharge them outside the camera. If you don't recharge batteries with the supplied charger,you will shorten the life span of the batteries or kill them.
Is it a bad idea to recharge regular AA batteries?
Attempting to recharge non-rechargable batteries can result in fire or explosion. Don't do it.
Use the word recharge in a sentence?
He went off to recharge his phone when its batteries died.
Does heating alkaline batteries recharge them?
If you put them over the back of a stove for a while they will recharge
How is a submarine powered?
Modern submarines are powered by a nuclear reactor. Others are powered by diesel engines while they are on the surface and batteries while they are submerged. The older ones that were powered by diesel and batteries had their limitations. While they were on the surface running on diesel engines they left a trail of exhaust smoke which gave away their position. When they were submerged and running on batteries they could only last so long and then they had to come to the surface, run the diesel engines and recharge the batteries. The submarines that are run by nuclear power do not have to resurface for a very, very long time.
What is the usual cause of batteries exploding during recharge?
Too much heat going into batteries, batteries are damaged, or batteries manufactured wrongly
What exactly are lipo batteries?
Lipo batteries are lithium polymer batteries. What makes them special from normal batteries is the fact that you can recharge these batteries so they last forever.
Why don't rechargeable batteries fully recharge?
It could be that the batteries are getting old and need to be replaced.
Do I need to recharge or plug in a hybrid vehicle?
There is no need to plug in a hybrid vehicle. The hybrid engine will recharge the batteries as needed by using the gas engine. Some newer hybrid cars even use breaking to recharge the batteries.
