Batteries - One Size Does Not Fit All

Batteries - One Size Does Not Fit All
By Dan Hagopian Platinum Quality Author

I have a Palm Zire 72 and a Palm m505 PDA. If I buy a Palm Zire 72 Battery that is 3.7 volts can I plug it into a Palm m505 and have that battery power both devices as needed?

In a nut shell the question above seeks to ascertain if all 3.7 volt batteries are the same?

The quick answer is no - all 3.7 volt batteries are "not" the same - and a battery specifically designed for a Palm Zire 72 will not be compatible with a Palm m505 PDA.

Let me explain.

It is true that all batteries share similar components and share common electrical measurements. But just because all batteries have some common components and measurements does not mean at all that you can interchange batteries with various devices even if the technical ratings are the same. Note that a component is something tangible and a measurement is intangible - a result of an action contained within the battery system.

Quick Review: What is a Battery and how does it work?

A battery in its most basic definition is a device that converts chemical energy into electrical energy. Batteries have two electrodes, an anode (the positive end) and a cathode (the negative end). In between the battery's two electrodes runs an electrical current caused primarily from a voltage differential between the anode and cathode. The voltage runs through a chemical called an electrolyte (which can be either liquid or solid). This battery consisting of two electrodes is called a voltaic cell.

Electrical measurements that can be gleaned from battery operations inclued the measurements of:

Volts - or V - is the electrical measure of battery's energy potential. For example you can think of energy potential as the pressure being exerted by all the electrons of a PDA Battery's negative terminal as they try to move to the positive terminal.

Amps - or A - which is a measure of the volume of electrons passing through a wire in a one second. One Amp equals 6.25 x 1018 electrons per second.

Watts: Volts x Amps = Watts. Watts are important because a watt represents the electrical energy spent by a battery (power generator) and used by an electrical device. Watts in effect is the measure of the amount of work done by certain amperage (amount) of electric current at a certain pressure or voltage.

Now beyond that basic review of the common components and measurements of batteries begins the radical differences between batteries. If you have a PDA, MP3, MP4, Laptop, Cell Phone, Smartphone, DVD players, or other electronic devices then more likely then not the battery within your device is a high capacity smart battery pack.

What is a high capacity smart battery pack? A high capacity smart battery pack is a complex battery system designed to power high tech electronic devices.

To construct a smart battery the battery manufacturer must carefully plan the internal battery design environment by considering the:

  • design parameters
  • current requirements
  • capacity and runtime requirements
  • temperature requirements
  • safety requirements
  • ambient operational/non-operational temperatures

As a design for a smart battery pack is considered manufacturers must evaluate the differences in components in relation to their design environment. Proper component evaluation and specification selection based on the intended application will determine the ultimate performance of the entire battery.

To give you an example of why smart batteries are carefully designed consider a PDA that when turned on explodes (don't think it can't happen) thankfully it occurs very rarely. To be a more reassuring the US Consumer Product Safety Commission has noted that 339 battery-related overheating incidents have occurred since 2003. Since conservative estimates puts the sale and use of devices containing smart batteries in excess of 100 million battery related devices during the same period makes the 339 incidents reported by the Saftey Commission at .000003% (a very small percent) of all battery related devices on the market. What is preventing more battery related fires -reliable and safe design under worst-case conditions is especially critical when designing with lithium based batteries. Specifically over-voltage and under-voltage of the cells and over-current of the battery pack.

Now with all this said I can tell you again, almost emphatically, that not all batteries are the same. From battery to battery the internal design will be different depending on the device the battery was specifically built to work within.

History of Cable Television and Alternatives to Cable

History of Cable Television and Alternatives to Cable

The Invention of Cable Television & Alternatives to Cable TV

There are many claims to the first CATV system, but only one thing is for certain; it originated in the United States and, according to one famous recollection, cable television had its beginning in 1948 in Mahanoy City, Pennsylvania. Community antenna television, as it was then called, was invented by John and Margaret Walson out of a necessity to bring television to their customers. They owned The Service Electric Company, a company designed to sell, install, and repair appliances. When they started selling television sets in 1947 their Mahanoy City customers were reluctant to buy because of reception issues. This particular region of Pennsylvania had difficulties picking up the stations in nearby Philadelphia due to the mountains that surrounded them.

To solve this problem, Walson installed an antenna on a utility pole that he placed on a local mountain top. It allowed him to demonstrate that the televisions could pick up good broadcasts coming from some of the Philadelphia stations using modified signal boosters and cable to connect the antenna to his store. So, in 1948, he charged a small fee and connected the antenna to several of his customers' homes as well, marking the beginning of the cable television business.

The early 1950s saw further development of the cable system. By then, the FCC had released its hold on a three year long freezing of new television station construction and had "assigned a nationwide television broadcasting plan", leading to the fairly rapid development of new television stations. Department stores began to encourage television viewing by displaying several different models for sale. Of course, this meant that television antennas had to also be sold. At the time, each home or apartment required its own antenna, creating a somewhat unsightly "forest of antennas" on the roofs of some apartment buildings.

This prompted Milton Jerrold Shapp to create a system that used only one master antenna for an entire building. He did so using coaxial cable and signal boosters, enabling the cable to carry several signals at once. Not too long after that, another appliance store owner experiencing the same problem as that of the Walsons read about Mr Shapp's system. Figuring that, if it could work for apartments and department stores, it could work for an entire town as well and he set up the first cable television system similar to how we know it today.

Because of Mr Shapp's innovative new system, television spread like wild fire throughout the country, enabling remote and rural areas to receive a signal and "by 1952, 70 'cable' systems served 14,000 subscribers nationwide". But, of course, people would not remain content with allowing the cable system simply to be used as a means of providing better signal strength to rural areas.

Toward the end of the decade, cable operators began using technologies to pick up signals from stations hundreds of miles away, irreversibly changing the way the cable and television industry operated. This new found ability to import more signals from distant stations also allowed for more programming choices. Now, the cable systems that only allowed for three channels (one for each network) soon changed, allowing room for seven or more channels due to the fact that they could pick up programs from distant independent stations (2). This created more interest in cable as a provider for city television as well because of the variety in choices it allowed.

By the early 1960s there were nearly 800 cable network systems in business. Many of these cable network companies started expanding into multiple cities, causing the beginning of the multiple system operator (MSO). Yet, the local broadcasters were afraid of the competition that cable companies were creating so they asked the government to stop the importation of signals by cable companies. The freeze that the Federal Communications Commission (FCC) placed on the importation of cable signals lasted until 1972.

In 1972 the service channels that people pay an extra premium for were started when Service Electric began to bill for Home Box Office (HBO). It had a minimal beginning with about a few hundred viewers the first night. However, it has become one of the largest pay cable services around. It is because of its success that so many others have followed.

In addition, the craving for more channels led the FCC to issue a rule in 1969 that required "all CATV systems with over 3500 subscribers to have facilities for local origination of programming by April 1, 1971". Furthermore, in 1976, the FCC decided to require that new systems must have more than 20 channels to choose from and that cable providers that had more than 3500 must provide public channels for education as well as government access.

Thus, cable television has been divided into two different services: basic service and premium services. Basic cable generally includes the local television networks and a few other common channels that are not transmitted with any type of encryption method while premium channels scramble their signals. They include channels such as HBO, Cinemax, Showtime, and Starz and are generally paid for in various extra packages in addition to the basic service.

The fees for service, whether basic or premium, did not defer customers and by the 1980s the major three television networks (ABC, CBS, and NBC) had all but lost their monopoly on viewers. "The era of network television" was coming to an end. Even other news networks began to emerge. "By 1985, 68% of all American households (60 million) had cable television service" . Cable News Network (CNN) first appeared on the scene in 1980.

With the emergence of all the new cable networks, cable television revolutionized the way Americans viewed television, and inspired many more changes yet to come. The invention of the VCR and, still later, the DVR would follow suit, yet again changing how American's use their televisions.

In recent years technology has begun to produce alternatives to cable television. As internet content grows to out weigh what cable TV services can offer. Many people have begun to migrate from cable television to Internet television. (24% in the US, 40% either use Internet TV alone, or a combination of Cable and Internet TV together) Internet TV provides the user with an opportunity to view all their favorite programming, most commercial free, in High Definition and directly to the users television. Internet TV. Internet TV has the potential to replace cable television as the preferred method of home entertainment delivery.

Savings and selection are mentioned as the primary reasons to switch to a Cable TV alternative. The average monthly cable bill in the US is between one-hundred fifty and two-hundred dollars per month. Internet TV in comparison has a one time fee for the home component and no additional monthly viewing fees. Users who wish to use services like Netflix and Blockbuster online may now watch movies directly on their HD television. Internet TV does not bypass legal means of content delivery, you must still pay the fees associated licensing fee for movie rental sites like Netflix and Blockbuster.

Free Internet TV content currently licensed for viewing online in high definition. (Short list) All programming from the major television networks; ABC, NBC, CBS, FOX, most cable networks (CNN, E!, etc) also broadcast their programming online for free. Some advance the broadcasts online before airing on their cable networks. Hulu, Fancast and Spreety are among a few providers available who collect all the legal content in one place for easy viewing by the user.
