Diesel-electric submarine batteries have become pretty sophisticated and efficient - during WWII, only a couple of days or less between battery charges was the norm. Today, DE boats can go well over 20 days or more between charges, assuming there's no significant battery loading (flank speed maneuvers, etc.)

How long can a submarine be in the water?
A nuclear powered submarine can remain submerged for as long as it has fuel rods and supplies for the crew.
How long could a world war 2 submarine stay submerged?
24 hours
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.
Why can an aquatic reptile remain submerged for a long period of time?
They have huge lungs
How long can you survive in a submarine without resurfacing?
The length of time a submarine can stay submerged without resurfacing depends on its design and capabilities. Some modern submarines can stay submerged for several months, while others may only be able to stay submerged for a few days. It is important for submarines to resurface periodically to replenish supplies and allow for maintenance and crew rest.
How long can a submarine go?
A submarine, theoretically, can go as long as the food for its sailors last. A submarine can make oxygen, distill water, remove CO2 and other pollutants, and provide almost anything needed to survive at sea and underwater for nearly an indefinite period of time. Modern nuclear-powered submarines' reactors will last without refueling for the life of the submarine - about 20 years. In 1960, the nuclear-powered submarine USS Triton circumnavigated the globe submerged.

How long was Jimmy Carter a submarine commander?
President Carter served as a Lt. Commander aboard a nuclear powered submarine, and qualified as a commander of a diesel powered submarine.In 1943 Carter was admitted to the United States Naval Academy. Upon graduation in 1946, he began his career in the submarine fleet serving until 1952. Promoted to a LTJG, he completed qualification for command of a diesel-electric submarine. In late 1952, he was admitted to the US Navy's fledgling nuclear submarine program led by then-Captain Hyman G. Rickover.
How did people in submarines get electricity?
Originally, a submarine's electrical supply was stored in large banks of batteries. The batteries were charged by generators turned by diesel engines when the submarine was on the surface. If the destroyers and aircraft could keep the sub down long enough, it would 'die' because of running out of power. Today's submarines generate electricity using steam from the nuclear power plants. This allows them to sever their ties with the surface for extended periods, which allows them to stay submerged for many months.
How long is a submarine sandwich?
A foot long submarine sandwich is 0.000189393939 miles long.
How big is 1 submarine?
The size of a submarine can vary significantly depending on its type and purpose. For example, a typical military submarine, like a U.S. Navy Virginia-class submarine, is about 377 feet (115 meters) long and can displace over 7,800 tons when submerged. In contrast, smaller research submarines may be around 20-30 feet long, while larger ballistic missile submarines can exceed 500 feet (152 meters). Overall, submarines range from small, personal submersibles to large military vessels.
Could submarines fire torpedos underwater?
Yes. The idea of the submarine is the element of surprise. Before nuclear power submarines ran on either battery power or diesel power. Every so often it needed to surface (or use a snorkle - no kidding, it's called a snorkle) to run the diesel (which would both propel the sub and charge the battery) Now, with nuclear power, the submarine can stay underwater as long as there is food for the crew. A submarine nuclear reactor can last for years.
