subject: Each Charge Before The Battery Discharge Is Not Necessary [print this page] Unusual at the very least be able to use more than one and a half hour battery ah you have some mistake ah? ? Such as:
1, first use the battery, the first three need to charge 12 hours?
This is totally unnecessary. Because it has a perfect laptop power management circuits, and charge management system, when the battery reached saturation, the control circuit will automatically switch to the open circuit state, so long as full on the line, not to say you charge the more longer you can use longer of.
Second, in order to prevent the memory effect, we should run out of power before charging it?laptop battery
Each charge before the battery discharge is not necessary, but also harmful. As proved: the depth of discharge of the battery will shorten the battery life meaningless, it is recommended when the batteries when used in about 10% can be charged up. Of course, there are still 30% when battery power for more than best to be charged, because the memory effect does exist.
3, insert the AC when the battery should be seized, and to prevent the repeated charge and discharge it?
I give advice to you is: do not! Of course, you can take the natural discharge of lithium-ion batteries to refute me, and that the natural discharge of the battery after the power supply access will occur if repeated charge and discharge, and reduce the battery life. I give you "instead of" This is the answer for several reasons:
1. Now all notebook power control circuit design of this feature: When the battery is 90% (such as HP's most models), or 95% will be charged, but to achieve this through natural discharge capacity of a time for 2 weeks month, when the battery is idle for a month or so to fully charge and discharge to maintain the battery's capacity, this time you should be concerned about is the battery little bit of exercise instead of being idle again after the charge.Dell Laptop Battery
2. Even if the battery "unfortunate" was once again charged, bringing the loss will not be long without the battery than the power drop caused by a large number.
3. Your data than you or your notebook batteries are much more rare, a sudden power failure has not only hurt your notebook, can not restore the data is no time for regret. Sept. 9 news, Hewlett-Packard did not let Dell laptops announced record the longest battery life too long. HP said that HP EliteBook 6930p notebook PC using an ultra-capacity battery can run for 24 hours. Earlier, Dell announced that its Latitude laptop battery life exceeded 19 hours mark.
