Battery Charging Instructions for Extending Battery Life

By:Bobby George

New batteries are shipped in a discharged condition and must be charged before use. We generally recommend an overnight charge (approximately twelve hours). Refer to the user's manual for charging instructions.

Rechargeable batteries should be cycled - fully charged and then fully discharged - two to four times initially to allow them to reach their full capacity. (Note: it is normal for a battery to become warm to the touch during charging and discharging).

New batteries are hard for the device to charge; they have never been fully charged and are therefore "unformed". Sometimes the device's charger will stop charging a new battery before it is fully charged. If this happens, remove the battery from the device and then reinsert it. The charge cycle should begin again. This may happen several times during the first battery charge. Don't worry; it's perfectly normal.

How Can I Maximize Battery Performance?
There are several steps you can take to insure that you get maximum performance from the battery:
Break In New Batteries

New batteries come in a discharged condition and must be fully charged before use. It is recommended that you fully charge and discharge the new battery two to four times to allow it to reach its maximum rated capacity.

Prevent the Memory Effect
Keep the battery healthy by fully charging and then fully discharging it at least once every two to three weeks. Exceptions to the rule are Li-Ion batteries, which do not suffer from the memory effect.

Keep the Batteries Clean
It's a good idea to clean dirty battery contacts with a cotton swab and alcohol. This helps maintain a good connection between the battery and the portable device.

Exercise the Battery
Do not leave the battery dormant for long periods of time. We recommend using the battery at least once every two to three weeks. If a battery has not been used for a long period of time, perform the new battery break in procedure described above.

Battery Storage
If you don't plan on using the battery for a month or more, we recommend storing it in a clean, dry, cool place away from heat and metal objects. NiCad, NiMH and Li-Ion batteries will self-discharge during storage; remember to break them in before use. Sealed Lead Acid (SLA) batteries must be kept at full charge during storage. This is usually achieved by using special trickle chargers. If you do not have a trickle charger, do not attempt to store SLA batteries for more than three months.

For Notebook Users
To get maximum performance from the battery, fully optimize the notebooks power management features prior to use. Power management is a trade off: better power conservation in exchange for lesser computer performance. The power management system conserves battery power by setting the processor to run at a slower speed, dimming the screen, spinning down the hard drive when it's not in use and causing the machine to go into sleep mode when inactive. The notebook users guide will provide information relating to specific power management features.

In 2007-08, India will launch Chandrayan I, which will be closely followed by China's CHANGE-I. Indian Space Research Organization (ISRO) is spear-heading all the activities in the field.
2). Looking To The Past Of Geothermal Energy By : Rick Solare Geothermal energy is often viewed as a relatively new form of alternative energy. In truth, the use of geothermal energy stretches far back into the past. Looking To The Past Of Geothermal Energy Geothermal energy is literally, �earth heat�. This type of energy's name comes from two Greek words: �geo� meaning earth, and �therme�, which means heat.
3). Alternative Fuel Source - An Urgent Need For One By : Ernest R. Peterson Using alternative fuel sources is not just a matter of environmental responsibility. It is not just about assuaging your conscience. It is good sense, and sound planning. Although most of us are in denial, the fossil fuels which form the backbone of our world economy are dwindling quite rapidly, even as we go about our daily business in our cars. Although few Americans use an alternative fuel source to commute, those who do are soon going to be at an advantage.

In 1999, chancellor Gordon Brown inaugurated a $1.6 billion program of "upgrading British science" and commercializing its products.

8). The Fossil Record And Creation Science By : Greg Neyman Young earth creationists commonly point to the fossil record in order to support their position. In one instance, the article "The Fossil Record: Becoming More Random All the Time" by John Woodmorappe, has some very good points to it (Footnote 1). Read it if you like, (its a long one), but you don't have to much farther than the abstract to see problems.

The National Science Foundation is responsible for providing support to basic science research, which is primarily accomplished through research funding. The National Science Foundation mostly provides research funding in the form of grants. These grants are most often given in the form of individual grants to graduate students and professors.

6). What Is A Fossil? By : Claudia Mann What is a fossil? While this is a simple question, the answer can be simple or a bit more complicated. The short and sweet answer to that question is �A fossil is the remains or evidence of any creature or plant that lived on the earth in a past geologic age.� But there are so many KINDS of fossils. A more important question for a curious student is �What kinds of fossils are there?� The answer to that question will take a bit more exploration.
7). Is Solar Power The Immediate Answer To Our Energy Woes ? By : L.Beauley We are looking for an across-the-board solution for our present exorbitant consumption of gasoline and it seems as though there is none, at least for the present. We are looking at Ethanol additive to our present gasoline formulas, but this will only give us better miles per gallon and of course, much cleaner bi-products with its use. Ethanol becomes a temporary fix.
8). The Energy Waste Dilemma By : L.Beauley Date: 04-23-06 With the price of gasoline on the upswing(again, April 20, 06), there seems to be little sign that we Americans are at least trying to conserve fuel, though there are pockets of concerned groups that are making their voice heard, mainly against Oil Company price gouging. At the same time the automotive advertising media seems to be pushing the higher gas consumption Suv's and cars.
9). Energy Conservation By : L.Beauley The Role We Can Each Play ========================= We can all play a part in lessening our reliance on fossil fuels. A- Use low-energy lamps such as CFL replacements for as many incandescent lightbulbs as possible in our home or apartment. B- Turn off all lamps in areas where they are not needed. C- Turn down water heater temperature to between 120-125 degrees.
