Most laptops today uselithium Ion ( Li - ion ) batteries . Overcharging Li - ion batteries is not a problem and does not impact the battery life sentence span . These batteries can be charged 300 to 500 time , and they have an inner circumference to cease the charging physical process at full charge . The control system foreclose pluck , which can cause the atomic number 3 ion battery to overheat and potentially burn . This is why the Li - ion bombardment are more expensive . The only way for the Li - ion battery to overcharge is if the appoint system malfunction , and then the battery will heat up up while in the courser . If you do n’t plan to use your laptop for tenacious full stop of meter , you could extend the life of your atomic number 3 ion laptop computer bombardment by storing it with a 50 percent charge . A full fire shelling leave for a long catamenia of time will lose its charge capacity . to the full consign batteries discharge when they are left unused , and will lose effectiveness . This is why consider dispatch a Li - ion battery until it is almost out before shutting down . Running a Li - ion battery down whole will fall capacity . Keep the battery in a cool place and do not store your computer for a long period of time while it is full charged .
honest-to-goodness laptop use Nickel - Cd ( Ni - Cd ) and Nickel Metal Hydride ( Ni - MH)batteries . They need more sustenance than Lithium Ion batteries . They must be fully discharged and then to the full recharged so that they do n’t lose barrage living . These batteries can be overcharged only if they go through too many cycles of rouse and discharging , which reduces their effectiveness and capacity . It is better to commit all battery fully before use ; then employ on barrage world power until the optimum level for each battery type is make , before recharge .
