(A) the need to activate the new battery
In fact, the activation of the battery work in the factory should have been completed, the laptop battery factory a little carried by the natural loss of power is to avoid damaging the battery. Activation of the battery protection circuit should be in no manner, and can be lithium batteries with protection circuit itself, the purpose of the circuit design blocks is to avoid over-charging and discharging the battery, usually when the battery is fully charged, the charging indicator light extinguished the moment, the battery is not charging the state, then this time you then plug the charger to charge the above do not have any meaning. We can see the status of the battery on the battery is charging, there is a simple way to determine if the battery is charging, the battery charge is going to be distributed in a certain degree of heat, when the battery is full after one hour (battery charger do not pull the power plug is temporarily down), you go touch the battery, this time you will find that the battery is at room temperature, it is because the battery charge status at this time has not, of course, there will be no heat generated.
(B) how to properly charge
Whether to use lithium batteries or Ni-MH Laptop battery, these batteries are a memory effect, Ni-MH battery memory effect significantly, lithium also has memory effect, but its memory effect compared to nickel-metal hydride smaller only. We have not heard of the so-called memory effect lithium argument, but that is exaggerated in some js to say, the purpose is wrong to guide consumers. Since the lithium battery has memory effect, then in charge should try to run out of rechargeable electric, Do not want to charge when the charge went, so although it convenient to use, but will shorten battery life. However, we did not need to completely run out of power again so charged, so too much trouble. Although this protection because the battery is not under the protection of the circuit will not destroy the battery, but nothing special needed. In fact, less than 3% of the electricity charge on it, the memory effect is an objective reality, but compared to natural wear and tear, it is not what it is.
(C) the need for an external power supply unplug the battery when
In fact, this depends on when you use an external power supply is not required to charge the battery, rechargeable battery is directly related to the life, in general, lithium battery charge and discharge times are fixed, the charge number to only 500 or so, at most not more than 800 times. Each of our battery to recharge a battery, the corresponding, thus reducing a number of charge cycles. But now many notebook manufacturers are taken into account the vulnerability of cells in increasing protection for the battery technology does not meet certain conditions will not be charged. Even so, when you use the computer for a long time when an external power supply is recommended that you disconnect the battery because the battery temperature is also the bane of one of the laptops in use will have a certain temperature, which is very harmful to the battery. Of course, if you are not sure of your battery, then I suggest you to pull down your battery and then use an external power
