Dell Inspiron 1526 battery

Your Dell Inspiron 1200 battery requires three complete charge/discharge cycles before use and achieving maximum capacity. It means the battery would have to be charged fully and then be discharged fully. Repeat it three times before starting to use the battery. By this way, battery's internal chemical materials can be activated and its internal chemical reaction can come into the optimal state. After the activation, the Dell Inspiron 1520 battery can be charged and used freely. 

Problem is it keeps on turning off mid process I'm guessing it's because the battery keeps on running out but it's turning off at percentages like "97% depleted" and then charging up to 100% really quickly, which surely shouldn't be happening?As annoying as this is I have noticed that for the two times it has turned off it has been more depleted/charged (although we're talking 1% each time, nothing special) so should I keep on just turning it back on each time until it reaches 100% either way? And how long will this take? I'm thinking days... In order to prolong Dell Inspiron 1521 battery life, fast charge will have to be switched to slow charge(namely Constant Voltage charging method) when battery reaches 90% charge.

 But the battery will have to be discharged completely once a month so that the battery activity can be released by such deep discharge and battery life can be maintained. If battery is idle for over 3 months, it is also necessary to conduct 3 cycles of complete charge and dsicharge to ensure that the battery is activated. Actually the battery needs to be used at least once or twice per month to release the battery power completely. Then fully charge the battery with AC power once. Please remember that it is always good for rechargeable batteries to use up the battery power before giving them a full charge. Because the li-ion Dell Inspiron 1525 battery used by laptop has its own laziness and would lose its activeness when being idle for long time.

 It is also suggested to shut down the laptop so that battery can be fully charged. Do not remove the AC power during charge. In addition, the power of battery can easily be used up and most laptops have only one battery. For this reason, some manufacturers have developed a fast charge feature that enables the battery to replenish its power at the fastest pace after power draining up. One hour charge can give the Dell Inspiron 1526 battery back over 90% of its power. Why is not 100%? Because frequent fast 100% charge will greatly shorten the battery life.It needs to be reactivated. It is suggested to take out the battery from laptop when it uses AC power supply indoor to avoid having the battery get charged frequently.
