Laptop battery use and maintenance

Laptop battery use and maintenance
Starting from battery materials said, current notebook battery is divided into three types: 1. NI-CR-battery, 2. nickel-hydrogen battery, 3. lithium battery; they are generally represented as: nickel cadmium, nickel-hydrogen NI-MH, lithium LI NI-CD.

1. activate the new battery

General practice is for manufacturers new notebook should be the first time you power on the battery with 3% power at this point, you should not use laptop batteries the external power supply, but residual battery power exhaustion until the shutdown, and then use the external power supply charge. And then also to after exhaustion of battery power and then charge, charge time must be more than 12 hours, repeated three times, in order to activate the battery.

2. minimize the number of times the battery

Battery charge and discharge times directly related to the life of each charge, battery retired to step forward. Suggest that rechargeable laptop batteries you try to use the external power supply, battery should be removed when using external power supply. If you frequently multiple times in a day-plug power supply, and laptop computers equipped with battery, battery damage more. Because each external access is equivalent to the power supply to charge the battery, battery has naturally so enjoyed as to reduce life.

3. power exhausted after charging and avoid charging time too long

Regardless of the laptops use dian349cbd lithium or NiMH, power must be exhausted before filling (is lower than 1%), which is the best way to avoid memory effect. Lithium will also have memory effect, but its memory effect smaller than nickel hydrogen, battery capacity only completely used to it after the charge. Part of the filling, discharging chemical properties that may cause the battery inside the cell is not consistent, and battery performance degradation.
Recommended once every few months for the battery toshiba laptop batteries deep discharge to optimize battery performance. Specific approach is to use battery power has been used to a battery capacity of up to 0% (then the system will automatically enter hibernation or standby, depending on your BIOS settings). And then connected to the AC charger has been full of up to 100%.

Batteries after a long period of storage and discharge of the battery, there is a natural process, natural discharge has finished, this does not affect battery IBM laptop batteries capacity. Charge for the first time, you should continuously to 12 hour battery charging, and loop charging or discharging completely and three times (see the section on battery maintenance) to wake up completely new battery if the battery is stored for several months did not use, proposal to three full charging or discharging it. If a battery after 12 consecutive hours or three still does not charge after charge and discharge cycles, the battery cannot use need to be worse.
