Battery Tips
- 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.
- 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
- 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.
- 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.
- 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.)
- 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.
