    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.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 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.

    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 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.

    6.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.

     

    Achieve Maximum Laptop Battery Performance on the Road

    Laptop batteries are crucial when working on the road. To get maximum performance from your laptop battery, fully optimize the laptop's power management features prior to use. However, there is a trade off when setting your laptop power management. You will achieve better power conservation in exchange for lesser computing performance. The power management system conserves the laptop battery power by setting the processor to run at a slower speed, dimming the laptop screen, slowing down the hard drive when it's not in use and causing the machine to go into sleep or suspend mode when it is inactive. Your laptop user's guide will provide information relating to specific power management features.

    Increase your Laptop Battery Life
    Did you know that detaching your main laptop battery from your laptop would increase your laptop's battery life up to 75%? Our experience and testing have shown that even when you are plugged in with your laptop ac adapter and your battery is fully charged, the laptop will still use the laptop battery resources in small increments. This will put unnecessary charge cycles to your battery. Since typical li-ion laptop batteries have 375 charge cycles, having a fully charged battery inserted will put unnecessary charge cycles. The downside to removing your laptop battery maybe a loss of power when the ac adapter is accidentally unplugged or when there is a power outage.
