Battery Tips

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.What is Battery Care Instruction?

a. Your new battery comes in a discharged condition and must be charged before use (refer to your computer manual for charging instructions). Upon initial use (or after a prolonged storage period) the battery may require three to four charge/discharge cycles before achieving maximum capacity.
b. When charging the battery for the first time your computer may indicate that charging is complete after just 10 or 15 minutes. This is a normal phenomenon with rechargeable batteries. Simply remove the battery from the computer and repeat the charging procedure.
c. It is important to condition (fully discharge and then fully charge) the battery every two to three weeks. Failure to do so may significantly shorten the battery's life (this does not apply to Li-Ion batteries, which do not require conditioning). To discharge, simply run your device under the battery's power until it shuts down or until you get a low battery warning. Then recharge the battery as instructed in your user's manual.
d. If the battery will not be in use for a month or longer, it is recommended that it be removed from the device and stored in a cool, dry, clean place.
e. It is normal for a battery to become warm during charging and discharging.
f. A charged battery will eventually lose its charge if unused. It may therefore be necessary to recharge the battery after a storage period.
g. The milliamp-hour (mAH) rating of the BatteryValues.com battery will often be higher than the one on your original battery. A higher mAH rating is indicative of a longer lasting (higher capacity) battery and will not cause any incompatibilities. An BatteryValues.com battery will, in most cases, outperform the original by 30% to 50%. o Actual battery run-time depends upon the power demands made by the equipment. In the case of notebook computers, the use of the monitor, the hard drive and other peripherals results in an additional drain upon the battery, effectively reducing the battery's run-time. The total run-time of the battery is also heavily dependent upon the design of the equipment. To ensure maximum performance of the battery, optimize your computer's power management features. Refer to your computer manual for further instructions.

3. Battery Dont's:

a. Do not short-circuit. A short-circuit may cause severe damage to the battery.
b. Do not drop, hit or otherwise abuse the battery as this may result in the exposure of the cell contents, which are corrosive.
c. Do not expose the battery to moisture or rain.
d. 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.

4.How to classify the battery?

Batteries are grouped into following categories:
Alkaline battery
Zincic carbolic battery
Lead-Acid battery
nickel-metal-hydride
nickel-cadmium
Lithium battery
Li-ion battery
Li-polymer battery
Fuel cells
Solar cells
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?How to prolong the lifetime of battery?

1)Reason:
a.Charger or electro circuit can't be fit for the battery.
b.Overcharge and overdischarge, etc.
c.Battery can't comply with the charging requirement
2)Solution:
a.Use the original charger.
b.Charge the battery after it automatically powers off , then full charge the battery.
c.Avoid erroneous usage of battery, such as heavy pressure, short circuit, fall off and so on.

7.Why can't the battery be charged? How to solve this problem?

1)Reason:
a.The battery has no voltage.
b.There is problem with charger, as it has no output electric current.
c.Low charging efficiency due to external cause.
2)Solutions:
a.Test whether the charger has voltage and output electric current or not.
b.Check if the charger is well contacted with battery. c.Activate the battery with voltage and current 1.5 time higher then the highest ones of battery. (Use this method only when the battery can't be charged.)

8.What's the reason that causes battery with no voltage or low voltage? How to avoid this problem?

1)Reason
a.No voltage.
b.External shot circuit or overcharge, anti-charge
c.Cells expansion and short circuit caused by direct anode contact and continuous high efficiency electric current overcharging.
2)Solutions:
a.Check if the battery is without voltage or electric current.
b.Avoid short circuit.
c.Avoid collision and pressure among batteries.
d.Charge the battery after it automatically powers off , then full charge the battery

The usage of the new batteries
When you use a new lithium ion batteries that buy back lately at the first time, you should carry on to refresh and discharge completely 3 times. Namely the battery must be charged and discharged completely for three times, put electricity quantity to the utmost again. Not to use the battery until you repeat three times. Make sure the chemistry material in the battery being activated and the internal electricity chemical reaction of the battery enter the best appearance.

From then on, you can use random namely you can use it when charging, but you must guarantee there is once turn on electricity completely one month. Such depth turn on electricity can stir up the battery to activate the function, and it is very important for Prolong the service life of the battery. If battery hasn't being used for more than 3 months, When you want to use it, you must use the same method (refreshing and discharge completely 3 times) to charge and discharge it again before use to insure to activate the battery.

The maintain of batteries
The common charger battery save the energy via the chemistry reaction, so its capacity may be influenced by the temperature, unused time, surroundings and the use times.

The following is about how to optimize battery's maintain utmost for prolong the battery's use time. After charging the battery, you'd better not to use it until it being filled completely. If your battery is new or it's the first time you charge it, It's possible due to some reasons make your battery is't be filled fully. So in order to require the biggest function, you should do as follow operation:

Make sure charge and discharge completely three times, if your battery hasn't being used for several months, I advise you should charge and discharge fully it for three times.

You don't charge your battery until the energy in your battery is exhaustion. The charge and turn on electricity of the part may cause each chemistry function inside battery as a result the battery function will back to decline

Lastly I advise you turn on electricity depth every several months for optimize your battery.
