Notebook computers configured power laptop battery systems, including rechargeable battery and external DC power supply. AC power in a case, the user can use an external DC power supply for laptops, in the absence of AC power away from the office, then can only be powered with batteries. Thus, when the battery is the key to the core of the notebook computer, users will need extra attention to it.

Tip: If long-term use external DC power supply, you can not remove the battery to extend battery life.

Small knowledge: the first launch of the battery is nickel-cadmium batteries Compaq Presario R3000 battery(Compaq r3000 battery) (NiCd), these batteries have a "memory effect", each charge shall be required before discharge, very easy to use, and soon was nickel-metal hydride battery (NiMH) replaced, NiMH Not only there is no "memory effect" and make more per unit weight of 10% of the electricity. The most commonly used battery is lithium-ion battery (Li-Ion), it is also no "memory effect", as compared with the NiMH per unit weight gain more power, the price twice as high than the NiMH. In the same weight, this three kinds of battery time than is 1: 1.2: 1.9.

1. The proper use of the battery

The current laptops Compaq Presario X6000 battery are equipped with lithium batteries, although it is not nickel-cadmium batteries or nickel-metal hydride batteries, as a memory, but if you do not or can not be completely discharged battery power is full of a whole, so every three months on the lithium-ion battery fully charge and discharge an approach is very useful. In order to achieve the battery fully discharged, when the battery power remaining 10% must be prohibited when the system into standby and the prohibition of 3% into hibernation, so to ensure that the battery fully discharged battery to achieve real results. If Windows XP, you can enter the "Control Panel → Power → Warning" label, respectively, click on "low-battery alarm" and "a serious shortage of the battery alarm" 2's "action alert" button to remove all the options inside and then removed the These two options (Figure), so even if the battery power shortage will not be an alert, it will allow the battery run out and eventually shut down all Hp Pavilion ZV5000 battery(Hp zv5000 battery) power.

In addition, if the laptop is not used for a long time, lithium batteries will be idle for 2 to 3 weeks by means of self-discharge all the electricity consumed, so again, should he give it before use to recharge. At this point should be charging the battery charge to 12 consecutive hours, and the cycle of complete charge and discharge the battery three times in order to completely wake up. If a battery 12 consecutive hours, or after the third cycle of charge-discharge still can not charge, it means that the battery may have already gone, usually the battery at about 300 to 400 times (up to 400-600 times a special improvement) after charging and discharging battery capacity is only equivalent to about 75% of new battery.

Small argument: The above view is the official point of view manufacturers written instructions, is naturally supreme notebook users point of view. However, many users have found an interesting phenomenon that so that when the battery is full, after an hour (do not pull the power plug), Zaiqu touch the battery, the result is close to room temperature, it is because the battery is not charging and discharging status. In fact, the lithium battery protection circuit with the circuit itself, the aim is to avoid over-charging and discharging the battery. When the battery is full after charging indicator light went out, the battery will not charge into the electricity, and then you then plug the power plug to recharge the battery Hp Pavilion ZV6000 battery(Hp zv6000 battery) in the face of what use? In this regard, it is also laptop battery forum to discuss the most intense.

2. Use Precautions

To ensure the laptop battery can maintain a better working condition when in use there are some considerations.

(1) New bought the battery fully charged at least once a power, then power exhausted, the second only after fully charged formally. This can only fully activate the chemical effects of lithium batteries.

(2) When the notebook computer using AC power the battery out when it would be preferable to avoid them always in charge state. It can be recharged when the best off the laptop, the battery can be fully charged. Also, do not unplug the power in the charge half-way, and finished 30 minutes after charging before use.

(3) If using battery-boot after a few minutes, it is best not to take over the external power supply, but to let the battery Hp Pavilion DV1000 battery(Hp dv1000 battery) charge runs out after them.

(4) Sometimes there is connected to AC power the battery may not charge, it is because some vendors in order to prevent battery over-charge cycles and deliberately designed to record, and only less than 95% when battery started charging. In the notebook when charging, if the shows do not cut off the battery is already full of AC power, because the battery power at this time may be just about 80%, it is best able to maintain an external power supply for about 30 minutes charge time-out in order to ensure a fully charged battery.

(5) Long-term do not have the battery should be placed in the shade in order to weaken its internal self-passivation reaction speed.
