On The Lithium Battery Discharge Errors

"The more the battery discharge will be, the more the battery will be depleted," said Tom Hartley, professor of electronic engineering at NASA's NASA study to extend battery life. "Give the battery charge , The battery will be the greater the loss of lithium battery is best in the middle of the state of electricity, so the longest battery life.

First, the high and low power state of the lithium battery life has the most adverse effects, while the number of charge and discharge cycles but is secondary. In fact, most of the sale of electrical appliances or batteries on the identification of the number of repeated charge, are 80% of the discharge test based on the benchmark. Experiments show that for some laptop Lithium Battery, often the battery voltage exceeds the standard voltage of 0.1 volts, that is, from 4.1 volts to 4.2 volts, then the battery life will be halved, and then increased by 0.1 volts, the life reduced to the original 3 The long-term low-power or no electricity state will make the battery inside the electronic movement of the resistance is growing, resulting in smaller battery capacity. NASA NASA let the Hubble Space Telescope battery power consumption set at 10% of the total capacity to ensure that the battery can be repeated charge and discharge 100,000 times without having to update.

Second, the temperature of the lithium battery life also have a greater impact (mobile phones and other small electronic equipment can be ignored). The freezing point of the following environment may make the lithium battery in the electronic product to open the moment burned, and overheated environment will reduce the battery capacity. Therefore, if the laptop long-term use of external power supply will not take down the battery, the battery will be in the long-term excitement of the laptop, the more important is that the battery is 100 percent in a long time the state of electricity, will soon be scrapped.
