WHY do they make AA, AAA,  C, and D batteries  and not a B battery ??
549750
For a period of time in the early 20th Century there WERE in fact B batteries. They were used to supply the ANODE voltage ( Plate voltage ) in vacuum tube devices like early radio equipment.  With the improvements that soon followed in converting AC to DC, it became less expensive to 'develop' the B voltage from a circuit called a 'power supply' and use of B batteries was confined to  'portable' devices.\n\nWith the development of the transistor, B voltage was no longer needed at all, and B batteries virtually disappeared from the market.

Go to the mfg site and look it up.\n\nWhat are the companies that made them?  You need to give more details and people can give more help!\n\nGo ahead right now and add additional details to this question!\n\nGO ON !!!!\n\nAPS

No real methods.  They are NiMh (nickel-metal-hydride) and very resiliant.  They are generally good for about 600-700 charge cycles before they start to break down.  Just the nature of batteries.

There are lots of battery technonlogies. The common battery is made of carbon and zinc with an electrolyte that is primarily manganese. But other batteries use nickle/cadmium, nickle/metal hydride, mercury, lead/acid, and lithium compounds. So depends on what battery you are talking about.

What are you, Steven Wright?\n\nI bought some batteries the other day, but they weren't included.

batteries have an electrolyte solution inside them;  when they get old this solution gets depleted of charge carriers, but i suspect you can recharge them by shaking them all around, thus mixing up the electrolyte and getting a bit more juice out.\n\nalso possible is that when you hold them in your hand when you take them out, the batteries warm up.  this warming means the ions in solution move faster, and therefore have longer diffusion lengths, so you can eke a few more minutes of game time out of them that way.  this effect (in reverse) is also responsible for your car not starting on very cold mornings.

Not much is known about the actual chemisty of nickel-based battery passivation.  Some battery companies will even deny it exists.

Rechargable batteries can only handle a certain number of charge discharge cycles so if you discharge the battery before charging it you will actually shorten the life of the battery as opposed to simply charging it when you get a chance.

It was a safety measure to avoid electrocutions. It works even though it costs more for the wires. \nSome people think it was to match battery supplied electrical systems but that is not right.

infact the circuitry is so designed that the total power consumption is very small and thats the reason behind making such ICs using the nano technology. these days an IC may comprise millions of transistors allowing u to make the designs smaller and smaller. along with low cost

Hi there...\n\nProfessional battery equipment is needed to recondition any battery, and the LITHIUM ION are the most deadly .... \nIn battery shops accross the country, the service technicians will generally not TOUCH a lithium Ion. \n Where I am located, there is a shop, and they tell me that they would have to install a fire-brick fume-hood, with explosion proof shielding, and other specialized bomb disposal stuff, before they could work on the Lithium ion batteries.\n As one other answer stated, the batteries, despite being " no memory " unlike Nickle Cadmium batteries, which "remember" being both not fully charged, and not being fully drained, the Li Ion batteries just plain die. Another answer gives you a link to NI-Cads, which is useless. The charging and cycling of Li-Ion and Ni-Cad are completely different. With old Ni-cads, you can use an ordinary capacitor to zap the batteries back to life, once. The professionals use very sophisticated machinery to revitalize older Ni-Cads. Nickle Metal Hydride are in the middle of the pack, with a different set of characteristics.\n  YOUR batteries are the worst.\n\nIf over heated, they will bloat, crack, and gas will escape in a foot long flame  that will cut through solid bone.. ie ... it can ampute an arm or leg if you happen to get in the way. There are reports around the world of people being " burned" and in the hospital, from Cell phone Li-Ion batteries. Cell phone Li-Ion batteries that are bloated are capable of cutting through the side of an airplane, including the hydraulics, frames, and wiring....\n\nUnfortuneately, in your case, you are forced to just replace the battery pack... do not play with it!\n\nIn the future, you might want to charge the battery as often as you can - the battery WILL remember slowly dying by lack of use. If it is always kept charged, it will last longer. People are lazy and don't bother to charge batteries until they " have to ", and this will shorten the life of any battery.\n\nGood luck

Nicad batteries are old technology, they hold a memory... Nickle metal hydrate batteries are a new technology that is being used by almost all companies and do not have a memory...click on the links and they will give you all the info you need!

B battery (vacuum tubes)\nFrom Wikipedia, the free encyclopedia\nJump to: navigation, search\nIn electronics, a B battery is any battery used to provide the plate voltage of a vacuum tube. It is sometimes colloquially referred to as a "dry battery" (although there's no reason why a "wet" battery of suitable voltage couldn't be utilised for the purpose) The term comes from the days of valve (tube) radios when it was common practice to use a dry battery for the plate (Anode) voltage and a rechargeable lead/acid "wet" battery for the filament voltage.\n\nEven when the plate voltage rail is fed by a power supply rather than a battery, it is generally referred to as the "B+" line.\n\nhttp://en.wikipedia.org/wiki/B_battery_%28vacuum_tubes%29\n\nAND Check out\nhttp://en.wikipedia.org/wiki/List_of_battery_sizes

C's are a common battery type, any General, Hardware, or Electronics shop should carry them, Look for the second largest cylandrical type.

Zinc-carbon batteries, also called "Leclanché" batteries or dry cells, were invented in 1866. \nA zinc can serves as a container for the battery and as electrode (anode). \nA carbon (graphite) rod is placed at the center and used as the other electrode (cathode).\nThe space between the carbon rod and the zinc container is filled with a moist mixture of ammonium chloride, manganese dioxide, zinc chloride and carbon powder. \nThe chemical reactions produce electrons on the zinc electrode.  \nThe battery has a voltage of about 1.5 V, which decreases in time. The dry cell cannot be recharged or made to work again because the chemical reactions cannot be reversed.\n\nfor chemical reactions and more details see:\nhttp://en.wikipedia.org/wiki/Zinc-carbon_battery

check with the manufacturer of your phone or a local electronics store like Radio Shack.  Older cell phone batteries used to need to be drained fully in order to preserve their lives, but a lot of new cell phone batteries don't require that anymore.

DC is battery and they do not generate a current. They store energy for use upon demand. They also do not store enough energy to maintain transmission for long periods.
