How to calibrate the battery

Most laptop batteries are smart; meaning that they know how much energy is left. Such a feature has definite benefits but the readings are often inaccurate. A laptop may indicate 30 minutes of remaining runtime when suddenly the screen goes dark. Here is the reason why:

With use and time, a tracking error occurs between the chemical battery and the digital sensing circuit. The most ideal use of the smart battery, as far as fuel-gauge accuracy is concerned, is a full charge followed by a full discharge at a constant current. In such a case, the tracking error would be less than 1% per cycle. In real life, however, a battery may be discharged for only a few minutes and the load may vary widely. Long storage also contributes to errors because the circuit cannot accurately compensate for self discharge.Eventually, the true capacity of the battery no longer synchronizes with the fuel gauge and a deliberate full charge and discharge is needed to re-learn or calibrate the battery.

What happens if no battery calibration is done? Can such a battery be used in confidence? Most smart battery chargers obey the dictates of the chemical cells rather than the electronic circuit. In this case, the battery will fully charge regardless of the fuel gauge setting and function normally, but the digital readout will become increasingly more inaccurate. If not corrected,the fuel gauge simply becomes a nuisance.

At what point of a discharge does the reset occur? Lithium-ion is considered fully discharged between 2.5 and 3.0 volts per cell. The electronic circuit in the battery is designed to reset between these voltage levels. A problem occurs if the laptop cuts off before this low voltage can be reached. In such a case, an external charger with discharge function may be used. Cadex Electronics manufactures smart chargers and battery analyzers, both of which can be used to test and calibrate the smart battery.

All of the battery has a natural course of discharging, after preserving for a long time; it has already finished discharging naturally. This does not influence the capacity of the battery. While charging for the first time, you should charge the battery to 12 hours continuously, circulation fill, discharge three (consult battery maintain first) by waking the new battery up completely totally, if the battery deposit several months, propose, go on complete filling, discharging 3 times to it too. If one battery still can not be charged after the 12 hour or three circulations this battery can not use needing to change.

Knowing the information above, while use the machine we should pay more attention to these items 1 try to fully charge and discharge the battery while using the machine. 2 Fully charge and discharge the battery once every two months. 3 If there is problem about the battery, our advice is pls try it by yourself first or contact to the service center to examine the battery.
