HP Laptop Battery Super Blog Here

Advantage lies in its mobility specification, if it is 3 kg and above included in the income, or 1.5 kilograms under the ultra-portable notebooks, with the battery pack, they may come from an external power supply of further work is essential weapon mobile computing. Batteries in laptops are central, but the proper use of laptop batteries, but there are all sorts of stories, we have consulted in the design of laptops has extensive experience in research and development, combined with their own experience to show you briefly how to treat their own laptop batteries.

Firstly, kinds of popular practice that the use of electricity in the long hours, many users will remove the laptop battery that can extend battery life, in fact, do not remove too. For users who do not remove the battery must be careful not to frequent Plug Power, which is due to appear discreet power socket short supply will be generated in the battery charging and discharging process, and frequent charge-discharge operation will shorten the battery life, while for the battery on the user side, the best time to time (about a month), this will be the battery in his laptop and recharge so that the Laptop battery can maintain the best state, if the battery is idle for too long will lead to a reduced capacity.

Second, lithium-ion, the depletion of the battery is not necessary to conduct further charge that because lithium-ion is almost no memory effect. The so-called memory effect occurs in nickel-chromium batteries or nickel-MH batteries, these batteries are not completely discharged in the circumstances, produce a kind of crystallization reaction, which temporarily reduce the capacity of the battery, if you want to eliminate the memory effect can be several times the battery fully charged and discharged, it is likely to return to save the battery.

Some users have complained that certain features display battery capacity built in reliability is not high, because these products there is a special calculation chip Dell GK479 battery capacity. In general, the percentage of laptop batteries in the display still has a certain credibility, and should be noted that from time to time, it is preferable to conduct the calibration of the battery to correct the calculating chip battery capacity May contain errors. The calibration can be done through two methods: unplug the external power, turn off power management in energy saving mode and will self-discharge switch off your computer, use the BIOS or in calibration Random supplied by the associated software.

Another issue requiring attention is the use of the environment, while mobile computing is facing an environmental diversity, but at room temperature to ensure the use of battery life, or there are some advantages, too cold ambient temperature on the overheating laptops will be damage. In addition, when using a transaction processing power from the outside will only support the operation of the system while charging the battery so that the process of charging in the off state compared to the charging operation will be slower if you want to load, it is preferable to the state off.

In short, while careful not to use common power supplies swappable, calibrate the hp F4809A battery on a regular basis to work and try to operate at room temperature, then the laptop battery will stay with you longer.

The process of loading the battery can generally be divided into pre-charge, fast charge, top-up trickle charge into four stages.

Term not used for long or a new battery, the top one on the use of fast-support, it will affect battery life. Thus, the Laptop battery should charge a small current load to meet certain conditions, this step is called pre-load.

Fast charge is to use the current pricing stronger, faster recovery of the battery power. Fast-charge rate of 1C or, more generally, the fast charging time, the battery capacity and loading rate-determining.

To avoid overcharging, the charger uses a number of low load current. The normal charge nickel-cadmium batteries can accept the charge rate of C/10 or less, so the charging time to over 10 hours. The use of low load current, the battery does not produce too much gas, the battery temperature is too high. As long as the battery charger, receiving the low rate constant-current apple A1079 battery charger will be able to provide a very small net charge current. Rechargeable battery with low current, the heat generated within the battery can be dispersed naturally.

Trickle Charger main problem is charging too slow, for example, with a capacity of 1 Ah battery, using C/10 charge rate, charging time to over 10 hours. In addition, the battery re charge a fill rate is low, when there is a dendrite. In most loader drip, lack of feedback voltage or temperature and therefore can not guarantee that the battery is fully charged, immediately after the bifurcation charger.

Fast charge constant current charging and pulse charging points are two types of constant current load is a constant current to the load current, the pulse load is the first use of pulsed current to charge the hp F3172A battery. And then let the battery discharge and so on. Great battery pulse amplitude, width very narrow. Usually discharge pulse amplitude for pulse charging 3 times. Although the amplitude of the pulse discharge and battery capacity related, however, with the ratio of current amplitude load remained unchanged, the charging process, nickel cadmium batteries reduced to hydroxide nickel hydroxide, nickel, cadmium hydroxide, cadmium restore. During this process, the bubbles generated, gathered at the plate on both sides, so it will reduce the effective area of the plate, so that the plate resistance increases. Since the effective area of smaller plates, the charge in the full time required to increase capacity.

Join pulse discharge, the bubble left the plate and with the negative plate composed of oxygen. This process reduces the depolarization of the internal pressure of the battery temperature and internal resistance. At the same time, most of the charge in the Dell GK479 battery is converted into chemical energy rather than gas and heat.

Charge-pulse width of discharge must be chosen to provide the plate to restore the original crystalline structure, thus eliminating the memory effect. Using measures of depolarization of discharge, may improve the efficiency of charge and allows very rapid charging current.

The use of some fast-load only the right, after the end of fast charging, the battery is fully charged. To ensure the recharge to 100% of electricity, but also by adding up the loading process. Complete the charge rate is generally not exceed 0.3c. By completing the charging process, the temperature will continue to increase when the temperature exceeds the limit, the charger into the charge state of maintenance.

Store, nickel cadmium batteries will power the discharge rate of C/30 to C/50 reduced to compensate for battery self-discharge due to the loss of electricity to supplement the charge after the end loader runoff should be transferred automatically to the process of electricity. Trickle charge, also known as maintenance costs. According to the battery self-discharge characteristics of slow loading rates are generally low. While connected to the battery charger and the charger connected to power in maintaining the state of charge, the charger load an additional rate to the battery, it will give the battery is fully charged, the state’s total.
