Laptop Battery basically is 2 ~ 3 years time, basically can't save much power, about and notebook regeneration cycle is same, therefore, note may use the previous year, or with secondhand when to buy some of the battery can be good quality raise price point.
Error: laptop batteries will need not just power after all in charge
Now of laptop batteries HP 403808-001 Battery are lithium battery, for lithium battery is concerned, with longer time test with no any role, or even harmful. Lithium battery does not exist because of the so-called "cache effect", only the early nickel battery just have this feature. Notebook battery life generally only with artificial damage or natural about life. Basically, the battery life is fixed, 300-600 times the number of charging and discharging, generally available in 2 years.
Myth: in again when the power supply, the battery can be also don't pull out
Pull out and not to pull out depends on the actual usage: in the connection of the dc power supply at the same time not pull out the battery HP 371916-001 Battery to the battery and without any damage, for the battery in full of electricity will not be accepted after any into power, electricity directly to all the power supply system notebook. But when the notebook at high speed, and internal overheating when had better or remove battery, otherwise is harmful.
How to correctly to laptop battery
Should try to avoid waiting for battery went dead again run out of charge, because that will give the battery pressure and cause damage. A feasible way is in the remaining 20-30% power is about to charge. In fact notebook of lithium battery HP 371913-001 Battery in the "light/charging the number of times" is limited, all run out of recharging will only shorten battery life. At the same time, the battery should be more dry place in charge, and to pay attention to heat problem, this is the great enemy of the battery.
Tip: the use of the cell phone battery HP 383963-001 Battery with the use of laptop batteries are not the same, and many people may it according to their cell phone batteries use to judge the experience, think laptop battery recharging shall also be all run out, this wrong.
Long-term use of laptop batteries not how to save
Notebook battery HP 396600-001 Battery electric light is preserved or should be full of electricity kept? Light electric long-term preservation can make core lose activity, and even lead to control circuit protection since the lock and can't use, full of electricity long-term preservation will bring safe hidden danger, the most ideal save method is to use electricity to about 40% and then stored in a cool and dry place, about 20 degrees Celsius is the ideal temperature preservation. Of course, every month to take out the best batteries with time, which can ensure the battery good save state, unapt let total loss of power and damage to the battery.
Extend the laptop battery time work several measures:
1 > lower screen brightness: can use fn + down/up key combination fast to adjust the brightness (specific fn + which button needs to see their laptop).
2 > use standby, dormancy function:HP HSTNN-IB45 Battery when a long time not using computers, can make your laptop standby or dormancy, already save electricity and extend the service life of the computer.
3 > open CPU speedstep function, can greatly extended batteries work time: CPU speedstep function in the BIOS is the default start, when use the battery, the CPU will automatically fall frequency of use to the energy-saving objective. As no open,HP HSTNN-UB17 Battery can according to boot into the BIOS Performance found in F2, set for Speedstep Enable Enabled.
4 > in the use of the battery HP HSTNN-DB20 Battery, try to close the wireless, bluetooth and infrared port. At the same time use to remove the peripherals and avoid enable big 3 D programs, games etc, in order to reduce unnecessary battery consumption.
