They use batteries quite similar to car batteries. Sealed lead-acid batteries. They are huge. Bigger or smaller subs will of course have different sizes and amounts. Batteries produce waste gas and hydrogen when charged or discharged and must also be ventilated regularly to prevent build-up.
Many of the early submarines ran on diesel engines. These were used when on the surface for propulsion and power, as well as charging the batteries. When they submerged, they ran on electric power from the batteries.
All submarines have storage batteries. Diesel-electric boats like the ones used during World War II are still used by the navies of some countries. Nuclear-powered submarines also have storage batteries that are used as a backup power supply if and when the sub loses the use of its steam-powered electric generators.
Their batteries could discharge deadly fumes.
Nickel Metal Hydride or Lithium Ion batteries are the most widely used.
They were powered by diesel engines and batteries. The batteries were for underwater use and the diesels propelled the sub and charged the batteries while running on the surface.

Different batteries in all the different remotes. Just open the remote up and see what kind of battery it has.
The kind of batteries used in the PetSafe Wireless Dog Fence would be a 6-volt battery. There are many places where one could purchase 6-volt batteries like Amazon.

Different cellphones use different size, types and brand of batteries. Most of the materials used on these batteries though are Nickel Cadmium or as they are called Ni-Cd batteries.
During WW2, all the major countries involved used submarines.
