Batteries have different voltages because different devices require different voltages to function. Batteries are manufactured to satsfy different devices' energy needs while minimizing voltage loss.

∙ 15y agoDifferent devices, such as flashlights and radios, have differing power requirements. the Walkie talkie makes use of one or two 9V batteries but economizes by using portions of the same circuit for both transmission and receiving, hence the push to talk or simplex operation- also used in much Ham radio. old time tubes had variable power requirements as more heat energy was needed for these vacuum devices to function properly, in Tube-radio days, such things as 9lVolt batteries by RCA were common. Modern transistor sets are much more efficient and do not generate undue heat or require warm -up time. my am-fm lasts about three months intermittent service with four penlights delivering 6 Volts DC. a Good radio. Likewise flashlights have variable power requirements. there you have it, submarine batteries, that"s something else.

∙ 14y agothere are many different types of batteries because it has to actually fit into the right voltage of your item. Batteries also depend on quantity. Like for example, if you still have a Game Boy Color... well you need 2 AA batteries! 'A' could possibly mean Alkaline... whatever that is! XD

What are the global batteries?
Global Batteries is a company that sells batteries for many different devices from AAA to Lithium batteries for laptops.
Do batteries last the same amount of time in different devices?
No, because different devices use different amounts of power.
What are the ways I can use twelve volt batteries in electronics?
Twelve volt batteries can be used for a number of different things. For example they can power small electronic devices. There are also a number of different brand such as Energizer and Deltran.
What are mechanical devices used to store solar energy?
Batteries.
What are the different types of batteries used in an electric car?
Normally Lithium Ion batteries or Lead-Acid batteries.
Finding Different Eveready Batteries?
There are many Eveready batteries in stores, but you should be certain that you are finding the batteries that are needed by your electronic device. Batteries can be expensive, and you don't want to end up buying ones that aren't going to work on the devices that you are purchasing them for.
HOW MANY VOLTS ARE IN THE BATTERIES WE HAVE USED?
The small batteries (dry cells) used for many electronic devices usually have approximately 1.5 volts. Car batteries (which have several cells working in series) usually have around 12 volts. Other batteries may have other voltages.
Where can I purchase alkaline batteries online?
An AA battery is a standard size of battery. Batteries of this size are the most commonly used type of in portable electronic devices. You can buy them at http://www.zbattery.com/Batteries/AA.
What are the economic uses of lithium?
Lithium is used in Lithium Batteries, which are used in computers. Also, Lithium is used to make Lithium-Ion batteries, which are used in many portable devices, such as MP3 players. Lithium used to be used to treat Mania Disorder.
Why is there different size batteries?
Originally they were all special built devices, with many different voltages and current capacities. What we have today is just a few remnants.
AAAA Batteries for Your Miniature Devices?
AAAA batteries are commonly used to power very small electronic devices such as computer styluses, penlights and laser pointers. About 4 centimeters long and weighing in at only 6.5 grams, AAAA batteries are small enough to easily fit inside such devices. Most devices use AA or AAA batteries instead, so AAAA batteries tend to be slightly harder to find. However, they are readily available at Amazon and other online stores, and they are made by Duracell and Energizer, among other battery manufacturers.
