Every time a friend buys a new computer , he asks me how to make its lithium HP 337606-001 battery has a long and prosperous life. When and how to recharge it last longer? should we expect them to be empty? should be removed when there is a sedentary use?here is a little technical overview of the life and death of lithium batteries, I hope you will understand how to prolong the life of your batteries.

The basis of the operation of a lithium HP 540 battery may be summarized in an exchange between the electrodes of the battery lithium ion .You have no doubt already heard several obscure technical terms such as lithium-ion (Li - Io), lithium-polymer (Li - Po), lithium-air, etc. These are batteries for the similar operation but using different materials such as electrodes and electrolyte. However these changes are more rare than lithium-ion and maintenance is relatively similar.

The main characteristic of a HP 530 battery is its ability (full load) expressed in watt-hours (wh noted). A battery of 1WH can provide a 1 watt for 1 hour. A typical laptop battery having a capacity 50WH (so in theory can provide 50W for 1 hour), will actually 5 hours if the computer consumes 10w. Other batteries are displayed in their ability ampere-hour (Ah) in this case they also state voltages. Since a × v = w, multiply the voltage by the ability to ah give you the ability to wh.The memory effect, primarily observed on the battery using nickel alloys, is a loss of observed ability when it reloads the battery until it is empty or it does not recharge to the end.In addition to their weight and volume, the main advantage of lithium batteries is the total absence of memory effect!

A lithium cell charge provides 3.6 to 3.7 volts. However they should never exceed this value (otherwise explosion) or fall below 2.4 V on pain of death pure and simple cell. Why lithium batteries include a control circuit that extinguishes before reaching this critical threshold.It is not dangerous to empty a lithium HP 550 battery to power is turned off, but it is dangerous to leave them unloaded in this state! Indeed, the batteries are not perfect, they exhibit a phenomenon of self-discharge, which could make them pass under the critical threshold of 2.4 v. Within a cell discharged, crystals can form on the electrodes and impede the ability of the battery. So do not leave a dead battery. Recharge it as soon as possible.For the same reason, if you do stop using your battery for several weeks, store it loaded about 40%, a value that limits the self-discharge.

After this extreme case, talking about the normal use of the battery: the discharge and recharge cycles. These cycles cause wear and tear of the HP HSTNN-IB17 battery . Depending on the quality of components used by your builder, your battery will survive from 300 to 1500 cycles before presenting a significant loss of capacity.There is one cycle every time you use the full capacity of your battery. Thus, discharge to 50% and recharge a battery account for half a cycle; twice this will cycle.To extend your battery so be the least possible cycles and the board will need to connect your laptop on AC power as soon as possible. Remember that there is no memory effect and therefore no reason to hesitate!

We often hear that when you are always connected to the mains it is better to remove the HP 520 battery from the laptop. This belief is essentially false because the control circuit of the battery will prevent overcharging.Disconnected the battery could self-discharge below the critical level of 2.4 V while connected to load will recover once it falls below 95%. However, note that it is true that heat can affect a battery in a computer but well designed it will not heat at this point.
