- How to correctly charge
- Unplug the battery whether or not when using the external power supply
I suggest it is unnecessary to re-charge when the computer automatic shutdown , and do not arbitrarily charge . In fact, regardless of laptop use nickel-metal hydride or lithium HP Pavilion ZV5000 battery , these batteries are have a memory effect, and nickel-metal hydride batteries with memory effect is very obvious, but equally there will be lithium memory effect, but its memory effect smaller than the nickel-metal hydride Bale . Well, since the battery has a memory effect, it should be noted when charging point, as far as possible and then run out of charge, but do not have to deliberately say must use the computer to automatically shut down, so that although there is no harm in using them.
Most people use an external power source, and removed the battery, only a few use an external power supply when the HSTNN-LB31 is placed above, but they used several international brand.
In fact, if the IBM thinkpad t43 battery is removed, the conflict focused on the use of an external power supply when the battery is charging to the issue. We should know that the number of charging and discharging the battery life is directly related to the general lithium battery set the number of charging and discharging are fixed number of charge cycles only 400-600 times, specially modified products, but 800 times, once for each rechargeable batteries a step forward to retirement. The first argument is simply because they are afraid to use power, the battery will be conducted on the above charge, not only increase the number of charge cycles, but will also cause overcharge. The second view is that the battery is full power on the computer in the use of an external power supply will not recharge.
After I investigated, many notebook manufacturers are taking into account the vulnerability of the ibm thinkpad t61p battery, and the product added to the battery protection technology, and thus the corresponding different brand laptop battery charging protection technology is different, like some large firms in this area done very well, such as: IBM, Hewlett-Packard and so on. One of the most thoughtful consideration is that IBM, IBM's notebook computers can detect the battery discharge situation, ThinkPad notebook battery only less than 95% of the time will automatically recharge. This battery can play a very good protection. So, like the battery, you do not have the time to use pull down, because only when the capacity less than 95% of the time it would charge. But even so, if you are prolonged use of computers, or will the battery be removed to compare the good, because the long-running laptop heat generated when the battery will cause some damage. However, some other "little brand" laptop batteries, may not enjoy such treatment, because it has not done inside the battery protection technology. I like to use a certain brand of notebook computers, if the fully charged battery on the above, when using an external power supply was confirmed when the first charge about electricity, because the battery storage, will have wear and tear, can not reach 100%, while not 100% as long as , power supply connected to the charge. Each access to external power supply is equivalent to charging the IBM ThinkPad x41 battery once, although only a small charge will be the time. Therefore propose that we use when the machine according to their own circumstances, look at the laptop manual, choose whether to use an external power supply when the battery removed.
