Frequently Asked Questions
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.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
3.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.
4.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.)
5.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.
6.How long do rechargeable battery last?
Most laptop battery can be normal used in 400-500 charge and discharge cycles, in another word, a laptop battery should be normal in 2 year.
Suggestion: you should 100% discharge the battery power and overcharge it for 4-5 hours, to eliminate the memery effect, if it can not recover, you'd better to get a new one.
7.How can i store my Lithium Ion battery?
It is best to store a lithium-ion battery with a partial or full charge. Occasionally, a lithium-ion battery with a very low charge is stored for a long period of time (many months) and its voltage slowly drops to below the level at which its built in safety mechanism allows it to be charged again. If the battery is going to be stored for several months it's a good idea to take it out and recharge it after a few months. Better yet would be to actually use the battery every few months and then leave it partially or fully charged.
In addition: Make sure charger and discharge completely at the first three times.
8.Know About Laptop Batteries.
The most recent laptops use lithium ion batteries. Generally the life of a laptop battery is two to five hours, but if the laptop is being used very extensively, the life may get reduced to as little as one hour. The chemicals that are used inside the battery are usually degenerated when the life of the battery drops. It then needs to be replaced. Lithium ion laptop batteries can live long for one to five years. It depends greatly on the extent to which it is used.
