Battery Knowledge
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?
- Reason:
- Charger or electro circuit can't be fit for the battery.
- Overcharge and overdischarge, etc.
- Battery can't comply with the charging requirement.
- Solution:
- Use the original charger.
- Charge the battery after it automatically powers off, then full charge the battery.
- 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?
- Reason:
- The battery has no voltage. b.There is problem with charger, as it has no output electric current.
- Low charging efficiency due to external cause.
- Solutions:
- Test whether the charger has voltage and output electric current or not.
- Check if the charger is well contacted with battery.
- 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?
- Reason
- No voltage.
- External shot circuit or overcharge, anti-charge
- Cells expansion and short circuit caused by direct anode contact and continuous high efficiency electric current overcharging.
- Solutions:
- Check if the battery is without voltage or electric current.
- Avoid short circuit.
- Avoid collision and pressure among batteries.
- Charge the battery after it automatically powers off , then full charge the battery.
Why laptop battery recycling is important?
Laptop battery recycling is important because these products contain ingredients and components that are hazardous in nature, including toxic chemicals that can cause irreparable damage if they are released into the environment and not properly discarded. Recycling these batteries protects our soil from penetration by these chemicals.
Few people realize that almost 100% of batteries comprised of lead acid can be efficiently reused and kept from our soil. Following this protocol may cost more, but it prevents CO2 emissions and allows us all to enjoy a higher quality of life. Clearly, the prevalence of batteries in all of our lives only makes this priority more important to all of us.
How long should I charge my new Lithium-Ion laptop battery?
Lithium-ion batteries do not need to be calibrated. The current lithium-ion batteries for your computer do not have an internal memory. In addition, a smart internal chip in the lithium-ion battery can prevent it from overcharging.
Just make sure to fully charge your laptop before using your new laptop battery. This will allow a full charge for the battery and insure it lasts longer.
