Laptop battery is one of the most important laptop accessories, tt goes without saying that the proper way to use the laptop battery such as DELL Inspiron 1521 battery is very important. But a fact could be clarified , that is the actual laptop use time is often below the manufacturer’s nominal battery life, the reason is due to manufacturer’s testing process was conducted based on the system 30% of left and right in line with.

Then let us take a look at how to use a good laptop battery. First of all, when we start with a new laptop, we would no longer charge for 12 hours like early use of the nickel-metal hydride battery, because when the notebook’s power management software has reported fully charged by the pa-1650-01 adapter, the overshoot protection circuit would stop charging of the battery. But it is important to note that new lithium-ion batteries have an “activate” need which should be fully charged and then repeatedly run out for 2 or 3 times.

Quite a few people like to take the laptop battery out，actually this action would not only cannot extend notebook battery life, it will even affect their life. The reason is that when the lithium-ion battery is in a long-term relatively static state, that is to say, the battery without electricity or less when, probably just about 6 months of time, it will lose functionality of storing electrical energy. But if you stick to take the notebook battery down, you should fill up to 90% and to save the plastic bag in a cool place.

So specifically to say, how long the life of a laptop battery would be? Actually lithium-ion battery and no specific of “quality guarantee period”, the using life of a lithium battery of 8 cores will be limited by the number of charging, that’s probably around 600 to 1200 times. Some people will get the data of 300 to 500 times, but according to the current technology, the charging number about 1000 times can be guaranteed of.

To sum up, in the daily use, users have no need to take the battery out. What’s more, the so-called maintenance is simple to let the battery which is used about half a year to be fully charged and discharged by the dell PA-12 ac adapter at a time. There is one thing we should pay attention to is that we should not use any metal objects shorted anode and cathode discharge, as this will damage the battery itself completely.
