1. What is a battery?
In science and technology, a battery is a device that stores energy and makes it available in an electrical form. It converts chemical energy into electrical energy, producing an electric current when connected in a circuit. The finished battery is an electrically connected group of cells (wired in series) that stores an electrical charge and supplies a direct current (DC). We usually call finished battery as battery pack and unfinished battery is called as cell.
2. Battery dont's
(1) Do not short-circuit. A short-circuit may cause severe damage to the battery.
(2) Do not drop, hit or otherwise abuse the battery as this may result in the exposure of the cell contents, which are corrosive.
(3) Do not expose the battery to moisture or rain. Keep battery away from fire or other sources of extreme heat. Do not incinerate. Exposure of battery to extreme heat may result in an explosion.
3. How can I maximize battery performance?
There are several steps you can take to insure that you get maximum performance from your battery.
(1) Breaking 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 your new battery two to four times to allow it to reach its maximum rated capacity.
(2) Preventing the Memory Effect - Keep your 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.
(3) Keep Your 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 your portable device.
(4) Exercise Your Battery - Do not leave your 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.
(5) 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. Ni-Cd, Ni-MH and Li-Ion batteries will self-discharge during storage; remember to break them in before use.
(6) For Notebook Users - To get maximum performance from your battery, fully optimize the notebook's 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. Your notebook user's guide will provide information relating to specific power management features.
4. How to classify batteries?
(1) Alkaline battery
(2) Zincic carbolic battery
(3) Lead-Acid battery
(4) Nickel-metal-hydride
(5) Nickel-cadmium
(6) Lithium battery
(7) Li-ion battery
(8) Li-polymer battery
(9) Fuel cells
(10) Solar cells
(11) Other types of battery
5. What are the differences between Primary Battery and Rechargeable Battery?
A primary battery is not intended to be recharged and is discarded when the battery has delivered all of its electrical energy.
A rechargeable battery is a galvanic battery which, after discharge, is restored to the fully charged state by the passage of an electrical current through the cell in the opposite direction to that of discharge.
6. What causes short lifetime of battery?
(1) Charger or electro circuit can't be fit for the battery.
(2) Overcharge and over-discharge, etc.
(3) Battery can't comply with the charging requirement
The lifetime of a battery can be prolonged by:
(1) Using the original charger
(2) Charging the battery after it automatically powers off, then full charge the battery
(3) Avoiding erroneous usage of battery, such as heavy pressure, short circuit, fall off and so on.
7. Why can't the battery be charged?
(1) Test whether the charger has voltage and output electric current or not.
(2) Check if the charger is well contacted with battery.
(3) Activate the battery with voltage and current 1.5 times higher than those of the battery. (Use this method only when the battery can't be charged.)
8. What are the reasons that cause battery with no voltage or low voltage?
(1) No voltage.
(2) External shot circuit or overcharge, anti-charge
(3) Cells expansion and short circuit caused by direct anode contact and continuous high efficiency electric current overcharging.
It can be avoided by:
(1) Checking if the battery is without voltage or electric current
(2) Avoiding short circuit
(3) Avoiding collision and pressure among batteries
9. Battery Maintenance and User Instructions?
(1) A new battery usually maintains a discharged condition with very low capacity. It is highly recommended to fully charge new battery packs before using. You can refer to the users' guide of your electronic device for charging instructions.
(2) A new battery pack needs to be circled (fully discharged and recharged) three to five times to reach its optimum performance.
(3) Rechargeable battery will undergo self-discharging when left unused for a long period of time. Thus, it should always be stored in a fully charged state and kept in a cool, dry and clean place.
(4) To maintain the optimum performance of a battery pack, it is highly recommended to circle (fully discharging and recharging) it at least once a month.
(5) It is normal if a new battery gets warm when being charged or used. However, please pay special attention if the battery pack becomes excessively hot. This may indicate there is a problem with the charging circuit of the electronic device. Please consult a qualified technician if necessary.
(6) New batteries are hard to be charged. Sometimes, your electronic device may indicate a fully charged condition about 10 to 15 minutes when the new battery pack is being charged for the first time. When this happens, remove the battery pack and let it cool down for about 10 to 15 minutes then repeat the charging procedure. Sometimes, a new battery will suddenly refuse to be charged. If this happens, a suggested solution is trying to remove the battery from the device and insert it again.
10. Precautions when using a battery?
(1) Do not modify or disassemble it.
(2) Do not incinerate or expose battery to excessive heat, which may result in an exposure.
(3) Do not expose battery to water or other moist/wet substances.
(4) Avoid piercing, hitting, crushing or any abuse use of the battery.
(5) Do not forget to take away your battery from the device if you will not use it for a long time.
(6) Avoid short circuit of the terminals by keeping your battery pack away from metal objects such as necklaces or hairpins.
