Lithium battery protection circuit and the purchase method

  Lithium batteries generally accepted use efficiency and safety, making it even if the higher price, and still fast-growing sales. However, the poor quality of lithium batteries, such as secondary recycling lithium battery, false lithium battery protection circuit usually be modified or omitted, short circuit, leakage

To phone patriarch partners around even burst case time understanding of lithium battery protection circuit is essential knowledge for each phone family, after all, superior quality, with lithium battery protection circuit.

    1, the need to protect the circuit
  
    Lithium-ion rechargeable battery overcharge or over discharge, battery swelling, leakage and other anomalies, the protection circuit prevents the device itself or charger fault, or due to improper use, the battery is damaged and performance deterioration settings often appear

. In normal use conditions, the protection circuit is not working.
  
    To protect the installation location of the loop

    The protection circuit is fused with a single battery and battery plate, even if the failure of the charger or the machine itself, the protection circuit to prevent battery damage, leakage, characteristic deterioration. These protection circuits must be installed in the battery plates by professional public

    3, to avoid the protection circuit damage
  
    Avoid places strong electrostatic battery, for example, some laboratory precision near the small, open area thunderstorms.
  
    4, the safety of the battery charging temperature range:
  
    The battery charge is best between 0-45 degrees Celsius, in order to maintain the best and most secure state-of-charge, or easy to damage the protection circuit, and reduce the life of the battery performance. Such as a car parked in the sun exposure, battery that is not suitable for placement which.
  
    Consumers buy lithium battery should pay attention to the following aspects:
  
    1, marked a clear capacity
   
    No clearly marked capacity (1000mAh or 1000 milliampere hour) battery, likely is the use of low-quality batteries or recycling batteries (Japanese used second-hand dolly, air come to Taiwan and then with the new shell packaging); these two battery will hazard

Harm the phone market is flooded many low-cost battery, is the use of recycled dolly do, although the price is cheap, but life is short, inconsistent quality, careless use may damage your phone!
  
    2, there is no guarantee of standby time
   
    The continuous use of standby time, the battery into the phone to the next charging time. Generally a commercially available battery to the customer can not ensure that the standby time, and this is because the battery quality unstable relationship; many inexpensive battery because the use quality

Poor dolly, so standby to make very short.
  
    Some sales do not know the actual capacity of the lithium battery, just casually Oral own inability to QC verification, they wantonly trafficking market. Salesperson can not guarantee that the standby time is equivalent to not be able to guarantee the battery is not used

Inferior battery or battery recycling!
  
    Whether the installation of safety protection circuit board
   
    Unprotected circuit board, lithium battery deformation, leakage and the risk of explosion fear! . The vicious price competition, each seeking lower-priced protection circuit board, or simply omit the device, so that the market is flooded with blasting dangerous

Lithium batteries. The consumers protection circuit can not recognition from the appearance, completely rely on oral merchant must select credibility businesses to buy.
