Depending on the type of pocket radio that you are using, usually triple A or double A batteries will work. There are also a few pocket radios that require the same battery that is used for the phone, a lithium ion battery.
No; battery sizes vary based on the type of hearing aid used. Most hearing aids require one of five types of batteries, which are made distinguishable by color and size. The color which indicates the battery size is on the tab which is pulled off to activate the battery. Blue batteries are size 675, yellow batteries are size 10, brown batteries are size 312, orange batteries are size 13, and red batteries are the smallest size, 5.
The size of batteries you will require for the mini maglite is the AA. You will need two of them. These 2 AA batteries should give you hours of light.
Micro R/C helicopters require batteries. Micro R/C helicopters require double A batteries. You will need plenty of batteries. http://www.ehow.com/how_6505592_control-micro-flyer-helicopter.html
Yes there are several different types of batteries for hearing aids. There are several different types of hearing aids and they need different batteries. For example High-Power BTEs and Cochlear Implants require PR44 or 7003ZD batteries, BTEs and ITEs require PR48 or 7000ZD batteries, miniBTEs, RICs and ITCs require PR41 or 7002ZD, RICs can also use PR70 or 7005ZD batteries, and CICs require PR70, 7005ZD, PR63, or 7012ZD batteries. The names of the batteries just mention are the standard names for them, but there are also several other names for them. The kind of battery needed for a particular hearing aid depends on the type and size of the hearing aid.

Radios were out long before 1960, but in the 1960's the first transistor radio came out. Before that radios had been fairly large and hard to carry around since they needed to be plugged into a wall. The transistor radio was small enough that it could fit into a pocket ( about the size of the today's cell phone) and it ran on batteries. Add an earphone to it and it was a student's answer to not paying attention. Music could not be added to it and it most cases it would only receive AM radio, so depending on your area you may not get too many stations.
Pocket holes typically require 1 1/4-inch coarse-thread screws for softwoods and 2 1/2-inch coarse-thread screws for hardwoods.
American pocket watches classified as size 8 are 36.4 mm in diameter.
When there were no televisions, people either went to the games or listened to them on the radio. There was no other way to watch the games than to be there. There were photographs in newspapers, however. The radios in those days were monsters in terms of size. They used vacuum tubes since transistors were not invented yet, and they used expensive banks of batteries to get the voltages needed for the tubes. Newer tube radios were able to use line voltage. Then as transistors came along, the size of radios began to dramatically decline and even become portable.
You can't "recycle" a battery but there are rechargeable batteries. Rechargeable batteries range in size anywhere from AAA to car batteries.
Is just the right size to fit in your pocket.
