It is said that a great number of users are used to work connected with external notebook charger while the lithium-ion batteries are still installed. However, some of them come to worry if such a habit will reduce the battery lifespan.


To be sure, each lithium-ion laptop battery has got limited recharging cycles of about 300 to 400. Although some technicians can update the level to nearly double times, it seems that the battery will also be damaged if it is continuously charging all the day.


Such a concept sounds logical, but the laptop batteries are not so weak as they think.


recharging cycles, lithium-ion battery

In conventional practice, the internal calculation system won’t record a charging cycle by charging and recharging times by periods. That is to say, the power energy consumed will be counted. When the consumption has reached about 80% to 90% of the internal capacity, it has completed one recharging cycle.


Evidently, as long as the battery hasn’t consumed so much from the external power supply, it will reduce only a little in every single day.


As a matter of fact, when there’s notebook charger available, lithium-ion battery just doesn’t work at all while users can find it not in charging for most of time. In the process, only the internal circuits of batteries are consuming the internal power energy while it will not recharge until the remaining has reached about less than 96%.


And there’re also some other factors influence on the lifespan, such as heat, internal contaminations, moisture, dust and so on. Compared to keeping connected with power adapter tips, if users cannot store the lithium-ion battery correctly in suitable places, the damage will be more seriously.


Actually, someone had ever killed his unused laptop battery. When he needed to use the battery after a few months, he was disappointed that it was out of work already. In my point of view, good maintenance and agreeable environments are of the greatest significance.

Actually, my desk has filled with power supply taps and cables thanks to my special work. But at home, I am also accustomed to the light of AC adapter. If you have the similar habit, you must have seen that it is conspicuous light source in pitchy darkness. Without a switch power supply tap, such a habit is also a way to waste energy consumption.


notebook charger, power supply tap, standby mode

Maybe you can think it a storm in a teacup, but the report of notebook charger accumulative total energy consumption has really surprised me a lot.


As is exemplified with a 60W notebook charger, it has consumed about 60W in charging and 6W in standby mode. Such a volume can be compared to a charging mobile phone. If it has been calculated by months and years, the consumption is so horrible. Supposedly, you can learn about the produced carbon emission and pollution.


However, the notebook charger is only the tip of the iceberg in the office or at home, television, DVD player and other consumer electronics won’t have reduced their consumption in standby mode if they are still connected to the power supply taps.


Recently, I have discovered a very strange charger in France. Mayamax, as a universal charger designer company, they have produced a very simple and environmental protection AC adapter. After you have started to charge, the device can be shut down completely and automatically after about three hours. Although it still cannot be applied to laptop computer and other high-consumed devices, it has performed well in some small portable electronic products.


green charger

This kind of ecotypical charger has got inner calculagraph that can cut off the power when the limitation time has reached. If thus green notion has been realized in notebook charger, it is bound to be a revolution to solve many existed problems like security, consumption and pollution.


Before, the technology has become robusted, users had better develop the habit of shut off the power at any time. Power supply tap with switch is another good idea to decrease electricity consumption. Not only for your notebook charger but also for us, a healthy way will make a healthy life.
