As regards the use of AC when the batteries are placed or won on IBM notebook to have with you will be a. IBM laptop control circuit is better than a lot of mobile phone, full of electricity it will automatically cut off after the charging circuit for small current cycle and to maintain the IBM laptop battery power status, the circuit control design are the best IBM notebook power consumption at less than 95% before start charging, so you Do not worry, such as IBM laptop battery charger plug go on indefinitely ghost of that; if it had to save, it is recommended the battery outside the U.S. put a layer of cling film, this can be isolated from dust, and on cool place, and then come up with regular use it about充充电in order to avoid loss of activity of IBM notebook batteries.

     For IBM notebook use, how to use the percentage of recharge should be said that there is no excessive stress, as this notebook users if IBM will become very passive, the actual IBM laptop battery is also not so pampered.

Another problem the U.S. has more question, that is, whether there is need for calibration of IBM notebook batteries, IBM laptop battery how to calibrate? The answer is there is necessary because the IBM laptop battery use and charging of the destabilizing factors will cause the capacity of IBM laptop battery dropped, but this decline is not caused because of aging, so proper calibration can make this part of the loss of the capacity of recovery. Therefore regular IBM laptop battery calibration is very necessary to have one thing, such as a January-February.
