In the past, in the great era of nickel-cadmium technology and lead-acid batteries, it was effortless to charge laptop batteries.All you have to do is set up a circuit to adjust the voltage so that the charging current on the millihour (mAh) potential of the notebook battery does not exceed 50%.After a few hours, the battery on your laptop is fully charged.A few milliamperes over or below the maximum capacity are effortlessly tolerated, and the overall life of the laptop or computer battery is only slightly reduced.Ah shows the ability of amp to move within an hour.The level of this unit determines the time of use with a battery notebook.Of course, the power demand of the laptop will affect the service life of the battery.Although some laptops (with a large number of multimedia laptops configured) have 2-In some other laptops (especially those with small screens or SSD), battery power can be used up to 8 hours, even if they all use the same battery.In addition, most laptop brands offer an additional accessory alternative called dual-battery power supply, which provides two amps of current per hour compared to the normal type.A lithium-ion battery will normally perform a charge/discharge cycle of 600 to 800.This means your life in 1, 5 to 3 years.As mentioned above, please re-use your laptop batteryThe fill source (AC adapter) will remain unnecessarily fixed.The second key point is that each fillThe emptying cycle (or use) of the electric battery reduces performance.It's not surprising, of course.However, depending on the time you use it for the first time, it will surprise you.In terms of the energy generated per pound, lithium-ion laptops or computer batteries are one of the most advanced technologies. Here are some suggestions for proper use of laptop batteries: 1-The new laptop battery is usually empty.The initial filling must be as long as possible (at least 4 hours), and the battery power supply is usually not used until it is fully charged.Don't wait until the battery is completely empty to recharge, this method is for old-fashioned batteries.If you don't use your battery power supply, don't try to fully charge it, use it at least, and its occupancy is 10%.4 -Don't leave your battery in the car in the summer.The hot battery discharge speed is very fast and the cold battery cannot produce so much strength.5 -Make sure to plug the laptop charger adapter into the UPS instead of directly into the power outlet or surge protector.6 -If you have a nickelMetal hydrogen batteries, which are fully drained and charged once a month to maximize their ability to maintain costs.7 -Completely cost the new battery pack before use.The new packaging needs to be fully charged and discharged (in circulation) several times before reaching full potential ).8 -For a laptop that is replaced as a desktop, the battery must be replaced again3-per installation-Allow full discharge for 4 weeks.9 -Leaving the battery in the laptop, although using the power socket for a long time will keep the battery power in a state of continuous charging, which will reduce the life cycle of the battery.10 -Adjust your power selection.Set the screen and hard drive to turn off after a few minutes, in addition, make sure your technology is set to go to standby and/or hibernation.If you don't mind the potential performance loss, setting the laptop to run in max battery mode will run the laptop processor at the lowest operating frequency, greatly increasing the operating time.11 -Using hibernate in standby, the battery of laptop s will still be exhausted in standby, and hibernate will put the laptop or computer on the off state.12 -Keep in mind that when you remove the battery power from your laptop and use the power outlet at the same time, automatic battery backup no longer works.Make sure to plug your laptop into an uninterrupted power supply (UPS) instead of a direct plug-in socket or surge protector
