QUESTION How does hot/cold effect battery life?
ANSWER; Hot cad cold can influence how well batteries perform and how long they last. When you use or store batteries temperature plays a big part. General purpose zinc batteries work best when used at about 70F. If you use a battery on a really hot day it produces more energy but if you store it in a hot place it reduces its shelf life. Batteries stored at above 125F will deteriorate quickly. If you use a battery when it is cold two things happen; it will put out less energy and it won`t last as long. However storing batteries in a cool place (40F to 50F) will increase the shelf life.
If you move them from cold to hot several times though you`ll actually shorten the shelf life!
QUESTION What are the different types of batteries and what are the advantages of each?
ANSWER; Tandy EXTRALIFEstandard batteries offer lonq storage life low cost and good performance at lower temperatures. They are perfect for things you use occasionally like torches portable radios walkietalkies metal detectors and toys.
Tandy ALKALINE batteries deliver up to seven times the service life of standard batteries. They are an excellent choice for smoke alarms remote controls test equipment and hiqh current devices such as portab~e TV`s stereos powered stereo speakers CB walkietalkies and remote controlled toys.
Tandy NickelCadmium (NiCd) batteries can be recharged and used over and over. Even though the initial cost is higher NiCd`s are by far the most economical power source for the mast often used portable equipment. Our selection includes standard sizes and packs for camcorders cordless phone and remote controlled toys.
QUESTION What are Button Cell batteries?
ANSWER; `Button" batteries include alkaline lithium silver oxide and zinc air types. These batteries pack a large amount of power capacity into a small package. We stock replacement batteries for cameras watches vehicle alarm remotes calculators hand held electronic games and measuring instruments.
QUESTION What about special purpose batteries?
ANSWER; We`re the source for hard to find batteries too!. Tandy can supply most currently produced battery types including `communication` types for police and fire walkietalkies special baHeries for cordless phones computer backup camcorders pagers medical equipment flash units and much much more!!
AMPERE (A) The unit for measuring electrical current. Often noted as milliamps (mA) thousandths of an ampere.
AMPERE HOURS (Ah) The measure of battery capacity. Amperehours equals current in amperes multiplied by time in hours. The higher the number the longer the battery will deliver useful power Often noted as milliamphours (mAh) 1000ths of an Ah. DC Direct Current. Batteries produce directcurrent electricity.
ENERGY A battery uses chemicals to store energy. It converts this into useful electrical power when needed.
LEAKAGE Over time baiteries can leak damaging chemicals. If you are not going to use equlpment for some time always remove the batteries.
POLARITY Batteries have two terminals. One is positive (+) the other is negative (). Follow correct polarity (+ roe) when you install the batteries.
VOLT (V) The unit for measuring electrical pressure. Batteries are usually connected in series which adds the voltages. i.e. two AA batteries 1 I/2 t 1 I/2 volts or 3 volts DC (3VDC)
